Project: SR 826/I-75 Express Lanes Project – Design-Build
Client: FDOT District 6
Cost: $243 Million
Location: St. Lucie County and Indian River Counties, FL
Description: The Project includes the addition of approximately 13 miles of Express Lanes to be constructed; ten (10) miles along the SR 826 (Palmetto Expressway) and three (3) miles on I-75 (SR 93).
On SR 826, one to two express lanes in each direction will be provided beginning approximately 0.20 miles south of West Flagler Street (south of SR 836) up to a point south of the NW 154th Street Bridge. On I-75, one express lane will be provided in each direction from SR 826 and to NW 170th Street (2.0 miles south of the Miami-Dade/Broward County Line).
Improvements consist of widening both SR 826 and I-75, reconstruction on SR 826, new construction in the median of I-75, and an elevated structure connecting the Express Lanes on SR 826 to the Express Lanes on I-75 requiring 14 bridge widenings, retaining walls, 88 sign structures, and noise barrier walls. The elevated structure consisted of a continuous steel box girder bridge with multiple steel integral pier caps. The project scope also includes new drainage, lighting, Intelligent Transportation Systems (ITS), signage, and landscape.
