KCA was selected by FDOT District One for the PD&E Study of SR 70 from CR 29 to Lonesome Island Rd. in Highlands County. For this PD&E study, KCA will evaluate the rehabilitation or replacement of a 4.4-mile segment of SR 70, which serves as an east-west corridor across Central Florida from Bradenton to Fort Pierce. Within the study limits, the SR 70 corridor is classified as a rural principal arterial and is a part of the Strategic Intermodal System (SIS). The existing roadway is a two-lane undivided facility with 10-foot travel lanes and 6-foot (4-foot paved) shoulders. SR 70 is exhibiting severe pavement distress. FDOT conducted a geotechnical investigation and determined unsuitable material beneath the roadbed is likely the cause of the pavement distresses. Segments of SR 70 will need to be reconstructed to remove the unsuitable material to maintain an acceptable pavement condition. The existing 50-foot R/W width is a key constraint that must be addressed in the study. The narrow shoulders and border area along with the deep canals make reconstructing the roadway infeasible within the existing R/W. As a result, additional R/W must be acquired to reconstruct and rehabilitate the existing roadway. KCA will not only be looking at the reconstruction of the existing two-lane roadway but will also assess the need for a four-lane divided roadway. The KCA team is responsible for studying traffic and function, access management, pedestrian/bicycle/vehicular safety, utility coordination, stormwater management, wetlands and listed species assessment, cultural resources, conservation lands evaluation, noise and air, contamination, and public involvement.
