Intermediate Bridge / Drainage / Grading

The Florida Department of Transportation, District 04, is requesting bids for intermediate bridge, drainage, and grading improvements along State Road 712 (Midway Road) in St. Lucie County, with proposals due December 2, 2026. The project spans 0.642 miles from Glades Cut-Off Road to just west of Jenkins Road.

The scope encompasses maintenance of traffic (standard and special detour, traffic control officers, signalization, detection, barriers, retroreflective pavement markers, and business signs); mailbox relocation; runoff control (sediment barriers, inlet protection, and monitoring of existing structures); concrete work (removal and placement in Classes NS, II, and IV); reinforcing and roadway steel; structures (bridge replacement, overhead cantilever, temporary and permanent walls including MSE and retaining walls, and noise and visual barriers); drainage infrastructure (inlets, manholes, pipe culverts, endwalls, and mitered end sections); rip-rap; guardrails with end anchorages; asphalt; pavement markings (tape, detectable warnings, directional indicators, paint, and thermoplastic); signing (single-post, multi-post, tubular marker, and overhead cantilever); lighting (standard, under-deck, spread-footing, barrier-mounted, and mast-arm-mounted); signalization (mast-arm and pedestrian controllers); intelligent transportation systems (WWVDS, fiber, conduits, and splice/pull boxes); utilities; fencing; and sod.

The proposal budget estimate is $66.845 million. The contract term is 1,162 days with a flexible start time of 60 days from notice to proceed and a 10-day execution period. The project roadway is 0.577 miles with 0.065 miles of bridge length. No federal aid funds this project. Significant coordination is required for traffic control, including 3,920 budgeted hours for traffic control officers, approximately 58,346 work-zone sign units, roughly 8,000 linear feet of temporary barriers, and over 153,000 channelizing devices.
