Southern Road & Bridge

What Southern Road & Bridge does

Southern Road & Bridge, LLC (SRB) is a Florida-based, privately held general contractor founded in 2012 that specializes in the rehabilitation, preservation, and maintenance of bridges and other critical infrastructure. The company operates six core service lines: bridge rehabilitation, civil construction, emergency repair, maintenance contracts, marine construction, and water/wastewater management. SRB's project portfolio includes four of the ten longest bridges in the United States, and its work spans structural steel repairs, protective coating systems, concrete restoration, marine fender installation, and pile section repair. Notable proprietary technical work includes a custom hydraulic jacking system engineered for the Sunshine Skyway Bridge bearing replacement and purpose-built scaffolding for elevated structural access.

SRB serves public agencies, municipalities, and private infrastructure owners nationwide. The company is registered in eight states and DOT pre-qualified in nearly 40 states, enabling competitive bidding on public infrastructure contracts across the majority of the U.S. market. Its GTM is sales-led and enterprise-oriented: revenue is generated through fixed-price or cost-plus contracts awarded via competitive government procurement, with contract values documented up to $33.5M (Pioneer Memorial Bridge, WSDOT) and $25.9M (Berwick Bay Bridge, LA DOTD). Named customers include FDOT, LA DOTD, WSDOT, TxDOT, ALDOT, VDOT, the West Virginia Parkways Authority, the South Florida Regional Transportation Authority, the City of Chattanooga, and Pinellas and St. Johns Counties.

The business model is project-based, with revenue derived from one-time contracts ranging in duration from months to multi-year maintenance engagements (e.g., a 1,095-day contract with Pinellas County). SRB is expanding self-performed trades to reduce subcontractor dependence and capture more operational control, supported by an equipment fleet of 60+ trucks and 30+ pieces of heavy equipment. The company received the FDOT & FTBA 2025 Best in Bridge Award and has demonstrated schedule performance (Rainbow Bridge repairs completed six months ahead of an 18-month schedule). SRB is small by employee count (11–50), privately held, and operates without disclosed institutional funding, acquisitions, or AI/ML capabilities.
