​Project Overview​

D Squared Infrastructure provided Temporary Traffic Control Plan (TTCP) services for the Phase 1 Deep Injection Well Transmission Main project along US 1 (Overseas Highway) in Marathon, Florida. The project required maintaining safe and efficient traffic operations along a constrained and heavily traveled corridor while minimizing impacts to local residents, businesses, transit, and emergency services throughout construction.

​

Key Services

D Squared Infrastructure served as the traffic engineering consultant responsible for developing FDOT-compliant Temporary Traffic Control Plans tailored to project-specific construction phasing and access requirements. Services included evaluating existing and anticipated traffic operations, roadway staging, and access to adjacent properties; designing phased lane shifts, detours, and work zone configurations; and preparing temporary signing, pavement marking, and traffic control device layouts. The team also coordinated pedestrian and bicycle accommodations through active work zones, assessed temporary signal operations including timing and detection needs, and evaluated local considerations such as emergency response access, transit operations, special events, and seasonal traffic conditions unique to the Overseas Highway corridor.
