Need The purpose of this project is to address safety conditions pertaining to structural and functional deficiencies associated with the majority of the twenty-three Florida Keys. Historic Bridges through repair/rehabilitation and/or removal options. Over the years, the historic bridges have deteriorated to various states of disrepair. The bridges now pose safety issues for both trail users and boaters, as well as environmental hazards. In addition, the bridges were built to standards that do not meet current state requirements, thereby categorizing them as "Functionally Obsolete". The Project Development and Environment (PD&E) Study will further examine improvement optionsi costs, and funding sources. to address the deficiencies of the twenty-three bridges. The PD&E Study will also evaluate 1) retrofitting the Florida Keys Historic Bridges (without existing trail) to scenic overlooks, as well as 2) the potential reconnection (through the addition of a new structural component to fill the existing span gap) of the historic South Pine Channel Bridge, to allow for the completion of the Florida Department of Environmental Protection's (FDEP) Florida Keys Overseas Heritage Trail. It should be noted that four of the twenty-three historic bridges [Niles Channel Bridge, Bahia Honda Bridge, Seven Mile Bridge, and Channel #5 Bridge] contain span gaps or navigational breaks in order to meet United States Coast Guard (USCG) 40' and 65' vertical clearance navigational requirements as they traverse USCG designated navigable waterways. Inclusion of a trail facility on these four bridges will be evaluated through a separate study due to the challenges associated with building new bridge structural components to USCG navigational standards. The need for the project is based on the following primary and secondary criteria: PRIMARY CRITERIA STRUCTURAL AND FUNCTIONAL DEFICIENCIES Based on Bridge Inspection Reports conducted in 2012 - 2013 by FDEP and a review of the Bridge Inspection Reports conducted in 2013 by FDOT, the twenty-three Florida Keys Historic Bridges have been determined to be "Structurally Deficient" [defined as bridge elements that are found to be in poor condition or worse]. While the overall condition of the substructure of the twenty-one concrete spandrel arch bridges is satisfactory [receiving a National Bridge Inventory (NBI) General Condition Rating (GCR) of 6 (with O.as failed condition and 9 as excellent condition)], the overall condition of the superstructure (deck slab overhangs and transverse steel 1-beams) of each bridge ranges from fair to imminent failure [with NBI GCRs of 5 or lower] categorizing the superstructure as Structurally Deficient. The deck slab overhangs on numerous bridges have deteriorated so badly that portions of the overhangs are threatening to collapse into the water (the Niles Channel Bridge has already experienced this in 2011). Of major concern are the concrete spalls on the underside of the deck slab overhangs, exposing a significant amount of corroded reinforcing steel. Likewise, several of the transverse steel I -beams have deteriorated to a point where they are beyond reasonable repair; failure of the steel 1-beams is imminent. Generally, the transverse steel I -beams remain present on bridges that have had the deck slab overhangs removed. The exposed steel I -beams show evidence of corrosion, and severe rust stains are present where the beams meet the face of the concrete spandrel arches (substructure). Corrosion and rust is additionally Page 1 of 12 Project Description Printed. on: 11/23/2015 evident at locations where the transverse steel I -beams have been cut back to reflect the original 13-foot width of the bridges. Further, five of the bridges still have an abandoned utility pipe attached to the side of.the concrete spandrel arches. The pipe and pipe supports are in very poor condition. Even where the utility pipe has been removed, corroded pipe supports remain.. The substructures of both the Bahia Honda Bridge and Seven Mile Bridge range from satisfactory to poor condition. However, the steel truss and steel girder superstructure sections of the Bahia Honda Bridge range from imminent failure to failed condition [with NBI GCRs of 1 or 0]. Similarly, the.deck slab overhangs and steel girder superstructure segment of the Seven Mile Bridge range from imminent failure to failed condition [with NBI GCRs of 1 or 0]. It should also be noted that the handrails along the bridges are currently substandard as they do not meet the minimum FDOT height requirement of 42" for pedestrian and bicycle railings. This substandard element poses a concern related to trail user safety along the bridges and, thereby, categorizes the bridges as "Functionally Obsolete". The primary focus of this project is to address the integrity issues of the bridge structures in. order to improve safety conditions for trail users and boaters. Bridge closures (and hence closure of the Florida Keys Overseas Heritage Trail) . have already occurred due to public safety concerns. Signs warning boaters of falling debris have additionally been placed at various bridge locations.. The proposed bridge improvements (repair/rehabilitation versus removal of deteriorating cantilevered road deck) are specifically intended to: - Prevent the collapse of the deck slab overhangs and transverse steel I -beams (and, hence, falling debris into the surrounding sensitive environment); - Remove corroded steel within the concrete. spandrel arches to promote long term rehabilitation of the substructure and prevent further concrete substructure spalling; - Address the functionally obsolete handrails of the bridges as they do not comply with current FDOT design standards; and - Enhance the overall aesthetics of the bridges by addressing corroded, cracking, and deteriorating bridge elements. SECONDARY CRITERIA NATURAL RESOURCES Another need for the project is to reduce adverse impacts to the highly sensitive surrounding natural environment and associated resources (protected waters, habitats, and species) as a result of falling debris from the deteriorating cantilevered road deck of the bridges. The bridges span the Florida Keys National Marine Sanctuary which encompasses the Florida Keys, federal refuges. (e.g., Key Deer National Wildlife Refuge), state parks (e.g., Bahia Honda and Long Key), and FDEP designated aquatic preserves (e.g., Coupon Bight Aquatic Preserve at Big Pine Key). The Florida Keys National Marine Sanctuary is classified as Special Waters Outstanding Florida Waters, and the entire sanctuary is considered a Habitat Area of Particular Concern due to its important ecological role in the life cycles of federally managed fish species. Accordingly, submerged aquatic vegetation (seagrass), mangrove swamp habitat, coral and coral reefs, live/hard bottom, and sand/mud bottom found within the sanctuary serve as Essential Fish Habitat for several federally -managed fish species and their prey. The Florida Keys National Marine Sanctuary further provides important and/or critical habitat for a number of listed species such as the West Indian manatee, various species of sea turtles, the American crocodile, and elkhorn and staghorn corals. It should. additionally be noted that the bridges span Bahia Honda. State Park, also classified as Other Outstanding Florida Waters, and several Verified Impaired Florida Waters. Page 2 of 12 Project Description Printed on: 11/23/2015 As indicated through the above -identified features, the habitats and waters surrounding the bridges are highly protected. The proposed bridge improvements are intended to provide a holistic approach to addressing the falling debris of the deteriorating bridge- elements, thereby reducing potential adverse impacts (and more so cumulative adverse effects) to surrounding wildlife, habitat, and water resources. The FDOT and FDEP are interested in seeking blanket biological opinions from resource agencies in order to address concerns regarding the issuance of permits as well as associated mitigation strategies as a result of improvements in a -comprehensive manner. RECREATIONAL USE While the twenty-three historic bridges currently serve as part of the Florida Keys Overseas Heritage Trail, the trail facility is incomplete. Completion of the trail.over the last several years has been a challenge due to the deteriorating condition. of the superstructure -of each bridge, particularly as portions of the deck slab overhangs on numerous bridges have collapsed or are threatening to collapse into the water. For this reason, some of the bridges or spans of the bridges have been converted to fishing piers or have been closed for public access. The Florida Keys Overseas Heritage Trail Master Plan (completed in 2000) was -prepared by Monroe County in partnership with FDEP, FDOT, and the National Park Service to fulfill the expressed vision by Monroe County citizens to have a continuous trail along US Highway 1 spanning the length of the Florida Keys in order to 1) enhance community recreational opportunities, 2) provide safe non -motorized transportation to schools and businesses, and.3) enable residents and visitors to enjoy natural resources along US Highway 1 (such as federal refuges and state parks). As such, completion of the Florida Keys Overseas Heritage Trail is a top priority for citizens of the area, Monroe County, FDEP, and other project stakeholders. The project is intended to: - Reinstate the use of the historic bridges for recreational purposes by allowing for the completion of the trail; —Meet goals of the Florida Keys Overseas Heritage Trail Master.Plan and several other local plans; and - Enhance recreational opportunities for both trail. users and boaters by addressing the integrity issues of the bridge structures to improve safety conditions. Once repair/rehabilitation and/or removal options have been analyzed to address the deteriorating bridge elements, improvements intended to allow for the incorporation of a future trail facility on the historic bridges to complete the Florida Keys Overseas Heritage Trail [i.e., retrofitting the Florida Keys Historic Bridges (without existing trail) .to scenic overlooks and reconnecting the historic South Pine Channel Bridge to fill the existing span gap] will be evaluated as part of the PD&E Study. Project Description This project will address safety conditions due to structural and functional deficiencies associated with the majority of the twenty-three Florida Keys Historic Bridges through repair/rehabilitation and/or removal options.

These improvements are ultimately intended to allow for the incorporation of a future trail facility on the historic bridges to complete the Florida Department of Environmental Protection's (FDEP) Florida Keys, Overseas, Heritage Trail, a shared -use path supporting recreational activities. It should be noted that four of the twenty-three historic bridges [Niles Channel Bridge, Bahia Honda Bridge, Seven Mile Bridge, and Channel #5 Bridge] contain span gaps or navigational breaks in order to meet United States Coast Guard (USCG) 40' and 65' vertical clearance navigational requirements as they traverse USCG designated navigable waterways. Inclusion of a trail facility on these four bridges will be evaluated through a separate study due to the challenges associated with building new bridge structural components to USCG navigational standards. Page 3 of 12 Project Description Printed on: 11/23/2015 The twenty-three Florida Keys Historic Bridges span approximately 63 miles in Monroe County extending from East_ Rockland Key at Rockland Channel Bridge (Mile Marker 9.8), the southernmost historic bridge, to Lower Matecumbe Key at Channel #2 Bridge (Mile Marker 73.0), the northernmost historic bridge. The twenty-three bridges are a subset of forty- two bridges originally constructed as part of the Overseas Railroad, completed in 1912. The bridges are considered property of the FDEP's Division of State Lands Board of Trustees of the Internal Improvement Trust Fund as they serve as part of the FDEP's Florida Keys Overseas Heritage Trail. The bridges do not fall within Florida Department of Transportation (FDOT) right-of-way. The bridges are additionally a component of the Florida Keys Scenic Highway corridor and parallel existing .US Highway 1, which connects the islands of the Florida Keys to the mainland. While the twenty-three historic bridges are not included on Florida's Strategic Intermodal System (SIS) network, they span or are in proximity to a designated SIS facility (Atlantic Intracoastal Waterway). An ETDM Programming Screen is being conducted for this project by the FDOT in cooperation with the FDEP. Although, FDOT is leading the ETDM screening event, FDEP .is serving as the lead agency on the project. FDOT and FDEP, in coordination with other state and federal agencies, will review the twenty-three bridges as a single resource (and, .therefore, as one project) in order to facilitate a more holistic approach in addressing the bridge deficiencies. As such, the range of improvement options, costs; and funding sources to address the deficiencies of the bridges will be explored in detail and refined during the Project Development and Environment (PD&E) Study. Use of the bridges for recreational purposes will also be considered during the PD&E Study. Information resulting from the ETDM screening event is intended to inform the scope and cost of the PD&E Study. Currently, FDEP plans to seek state funding to conduct the. PD&E Study through a Legislative Budget Request in January 2016- While other potential sources to fund remaining project phases -are unknown at this time, the project will maintain eligibility to receive future state and federal funding. BACKGROUND The twenty-three historic bridges were constructed in the early 1900s as part of the Key West Extension of the Florida East Coast Railway (also known as the Overseas Railroad). All of the historic bridges, with the exception of the Bahia . Honda Bridge and the majority of_the Seven Mile Bridge,.are.of concrete spandrel arch construction. The Bahia Honda Bridge and a portion of the Seven Mile Bridge consist of steel trusses and steel plate girders, respectively. While each historic bridge varies in length, all were originally built to a standard width of 13 feet. In the late 1930s/early 1940s, the Overseas Railroad was converted to the Overseas Highway: As such, the 13-foot wide railroad bridges were widened to 27 feet (out -to -out) or 22 feet (curb -to -curb) to accommodate two vehicular travel lanes and railings, doubling the width of the traffic bed. Transverse steel I -beams, spaced 10 feet apart, were laid across the . width of the concrete spandrel arch railroad bridges to cantilever over the sides. These beams supported concrete overhang slabs and railings constructed from old Florida East Coast Railway track,A similar deck was constructed over the steel plate girders of the Seven Mile Bridge and on top of the steel trusses of the Bahia Honda Bridge. In the early 1980s, the historic bridges were decommissioned to vehicular traffic as new,. parallel vehicular bridges were constructed by the FDOT as part of US Highway 1. The twenty-three historic bridges that remain are listed on the National Register of Historic Places. Currently, the bridges exist in various conditions as a result of rehabilitation projects over the years. Based on Bridge Inspection Reports conducted in 2012 2013 by FDEP and a review of the Bridge Inspection Reports conducted in 2013 by FDOT, a total of fourteen bridges still have overhangs; four of these fourteen bridges [Ohio -Missouri Bridge, Ohio - Bahia Honda Bridge, Missouri -Little Duck Bridge, and Lower Sugarloaf Bridge] have been prioritized for immediate attention as the overhangs are in imminent failure condition. Accordingly, the deck slab overhangs have been entirely Page 4 of 12 Project Description Printed on:.11/23/2015 removed from. seven of the bridges and partially. removed from the Seven Mile Bridge. Some of the bridges have been rehabilitated in an attempt to preserve their historic character, keeping the corroded deck slab overhangs and transverse steel I -beams intact. In some cases,- the rehabilitation method involved adding Carbon Fiber Reinforced Polymer (CFRP) / Near Surface Reinforcement along the top surface of the center deck slab, continuous into the overhang slabs, to prevent the overhang slabs from collapsing. In addition, at least one bridge had additional steel braces added to support the deck slab overhangs. Further, some of the bridges or spans of the bridges have'been converted to fishing piers, or spans of some bridges have been removed to allow channel breaks for navigational purposes. It should be noted that while the twenty-three historic bridges serve as part of the Florida Keys Overseas Heritage Trail, the trail facility is currently incomplete. In 2000, Monroe County (in partnership with FDEP, FDOT, and the National Park Service) prepared the Florida Keys Overseas Heritage Trail Master Plan to fulfill the expressed vision by Monroe County citizens to have a continuous trail along US Highway 1 spanning the length of the Florida Keys in order to 1) enhance community recreational opportunities, 2) provide safe non -motorized transportation to schools and businesses, and 3), enable residents and visitors to enjoy natural resources along US Highway 1. As such, completion of the Florida Keys Overseas Heritage Trail is a top priority for citizens of the area, Monroe County, FDEP, and other project stakeholders. Once work to repair/rehabilitate and/or remove deteriorating bridge elements has been performed, improvements intended to allow for the incorporation of a future trail facility on the historic bridges (to complete the Florida Keys Overseas Heritage Trail) will be evaluated as part of the PD&E Study. ATTACHMENT 1: Bridge Inventory in the EST presents the existing conditions, repairs that have been performed to. date, and potential improvements proposed for each bridge. PROJECT SET-UP Due to the fact that the twenty-three historic bridges [presented as twenty-three individual feature segments in the Environmental Screening Tool (EST)] will be reviewed as a single resource, one ETDM Project has been established in the EST. However, for management and reporting purposes of EST data, the twenty-three bridges have been divided into three geographic clusters. Each cluster of bridges corresponds to an EST alternative. The three clusters (or EST alternatives) are defined below. Alternative 1- East Rockland Key to Big Pine Key The twelve bridges that compose Cluster 1 or Alternative 1, the southernmost historic bridges extending from East Rockland Key (south) to Big Pine Key (north), include: -Rockland Channel Bridge (Feature 1) -Shark Channel Bridge (Feature 2) -Saddlebunch #5 Bridge (Feature 3) -Saddlebunch #4.Bridge (Feature 4) -Saddlebunch #3 Bridge (Feature 5) -Saddlebunch #2 Bridge (Feature 6) -Lower Sugarloaf Bridge (Feature 7) -Park Channel Bridge (Feature 8) -Bow Channel Bridge (Feature 9) -Kemp Channel Bridge (Feature 10) -Niles Channel Bridge (Feature 11) -South Pine Channel Bridge (Feature 12) Page 5 of 12 Project Description Printed on: 11/23/2015 o� Alternative 2- Big Pine Key. to Marathon The six bridges that compose Cluster 2 or Alternative 2, the more central historic bridges extending from Big Pine Key (south) to Marathon (north), include: -Spanish Harbor Bridge (Feature 13) -Bahia Honda Bridge (Feature 14) -Ohio-Bahia Honda Bridge (Feature .15) -Ohio-Missouri Bridge (Feature 16) -Missouri-Little Duck Bridge (Feature 17) -Seven Mile Bridge (Feature 18) Alternative 3- Marathon to Lower Matecumbe Key The five bridges that compose Cluster 3 or Alternative 3, the northernmost historic bridges extending from Marathon (south) to Lower Matecumbe Key (north); include: -Toms Harbor Channel Bridge (Feature 19) -Toms Harbor Cut Bridge (Feature 20) -Long Key Bridge (Feature 21) -Channel #5 Bridge (Feature 22) -Channel #2 Bridge (Feature 23) TRANSPORTATION PLAN CONSISTENCY While existing US Highway 1 bridge improvements and projects to retrofit various Florida Keys Historic Bridges to include segments of the Florida Keys Overseas Heritage Trail are identified in the FY 2016 - FY 2020 FDOT Work Program, the State Transportation Improvement Program (STIP), and the Monroe County Comprehensive Plan 2010-2030 Update, uniform enhancements to address the structural and functional deficiencies of the twenty-three historic bridges are not reflected in the referenced plans. Several. local plans [including the Lower Keys Livable Communikeys Plan, US-1 Corridor Enhancement Plan, Florida Scenic Highway Interpretive Master Plan and Corridor Management Plan, Monroe County Bicycle and Pedestrian Plan, and the Florida Keys Overseas Heritage Trail:(FKOHT) Master Plan] currently classify the completion of the. Florida Keys Overseas Heritage Trail (extending from Mile.Marker 0 to Mile -Marker 106.5 using the twenty-three historic bridges), as a priority project. However, the FKOHT Master Plan also recommends the removal of the deck slab overhangs from all bridges where overhangs remain with the exception of two bridges. The Bow Channel Bridge and the Ohio -Missouri Bridge are proposed to be maintained to reflect the historical character of the old Overseas Highway, The Seven Mile Bridge and Bahia Honda Bridge are additionally recommended to be preserved. Once the scope for the Florida Keys. Historic Bridges PD&E Study is complete, FDOT will work to modify the FDOT Work Program and STIP to.ensure theidentified bridge improvements are included in these. above -referenced documents. These two documents will additionally be updated to reflect funding required for future project phases (Design and Construction) based upon the refined improvements, costs, and funding sources determined as a result of the PD&E Study. FDOT and FDEP will also coordinate with Monroe County, and the various municipalities along the project corridor, to ensure that the Florida Keys Historic Bridges project is consistent with the respective local comprehensive plans. Summary of Public Comments Summary of Public Comments is not available at this time. Justification A Public Involvement Plan (PIP) will be prepared and conducted during the PD&E phase of this project. Page 6 of 12 Project Description Printed on: 11/23/2015
