Project Details
The SR 76 PD&E study is being conducted by the FDOT in conjunction with Martin County and the FHWA (Federal Highway Administration). The study will document information necessary for the FDOT and FHWA to reach a decision on the type, design and location of improvements to SR 76.
Based on long-range planning, projected population and employment growth, and projected traffic volumes, the Martin Metropolitan Planning Organization (MPO) has made this project a priority in Martin County. The proposed project is included in the Martin County MPO's Year 2030 Cost Affordable Long-Range Transportation Plan (LRTP), and has been designated as a primary Multimodal corridor. MPO travel demand estimates indicate that in 2030, daily traffic volumes will increase by 60% on SR 76 due to the anticipation of high employment growth along the project corridor in the area east of I-95 and north of SR 76.
During preliminary planning for this project through the FDOT’s Efficient Transportation Decision Making (ETDM) screening process, concerns were raised by agencies regarding various potential impacts to the environment. Specific agreements with the FDOT have been made to include the following work in the project scope. See the ETDM web page for more information.
SR 76 is currently a two-lane undivided rural roadway from CR 711 (Pratt Whitney Road) to SW Locks Road and a four-lane divided rural roadway from SW Locks Road to Cove Road. There are existing paved shoulders for bicyclists on this segment of SR 76; however, there are no sidewalks or pedestrian facilities east of SW Locks Road. SR 76 is one of the few roadways that cross the Florida’s Turnpike and I-95, connecting the west and east sections of Martin County.
In this study we are developing various “Build” alternatives as well as a “No-Build” alternative. The proposed “Build” alternatives will consider widening the roadway and bridges on both sides to a four-lane (Figure 1) or six-lane (Figure 2) divided roadway. The proposed roadway will typically include 12-ft travel lanes, sidewalks, a shared-use path, and bicycle lanes. Additional “Build” alternative features include widening of the existing SR 76 bridges over SR 91 (Florida’s Turnpike) and the South Fork of the St. Lucie River. The SR 76 at I-95 interchange is located within the project study limits. The study team is currently analyzing concepts for improving this interchange. Potential improvements include modifications to the entrance and exit ramps, addition of turn lanes at intersections, or reconfiguration. The team, in coordination with Martin County, is also developing earlier or interim improvements. These can be implemented sooner to provide quick benefits and for lower costs than for the long term improvements.
As part of this study, environmental and social effects are being assessed. These environmental effects and preliminary cost estimates have been prepared for each Alternative and were presented at the Alternatives Public Workshop.
