The city of Marathon is starting a court-mandated deep injection well project to modernize its wastewater effluent disposal system and enhance long-term environmental protection.
That will mean closures of sections of the northern lane of the Overseas Highway on the south/westbound side.
Construction of the first phase of piping is expected to begin on Tuesday, Feb. 17. DBE Utility Services has been contracted to perform the construction work, with Apex Engineering conducting the construction engineering and inspection services. This phase includes the installation of new underground pipelines using horizontal boring, a trenchless method designed to reduce surface disturbance, limit conflicts with existing utilities and minimize disruptions.
Construction activities will occur within and adjacent to the Florida Department of Transportation (FDOT) right-of-way and will require temporary lane closures. Motorists should expect delays as 24-hour lane closures will be in effect for the duration of the project.
Closures will occur on segments of U.S. 1 from Marathon Community Park to the Vaca Cut Bridge. The first closure will occur from Aviation Boulevard to the Airport Access Road. Closures will shift along the corridor every six to eight weeks.
To expedite the project and minimize traffic delays, two boring rigs will operate simultaneously in opposite directions.
