Community Asphalt Corp.

Scope Of Work

This project consisted of the full reconstruction of SR-5 (US-1) from the South Florida Water Management District’s Canal C-111 (Mile Marker 116) to SW 344th Street (Mile Marker 128) in Florida City, Miami-Dade County. The project was designed and constructed as a PPP design-build project between the Florida Department of Transportation (Department) and Community Asphalt.

The project scope for full roadway and bridge reconstruction, which includes but not limited to clearing and grubbing, demucking, excavation, embankment, drainage, lime rock and asphalt base, asphalt pavement, median concrete barrier wall, construction of a three-span bridge over the C-111 Canal and two single-span wildlife crossing bridges, temporary and permanent Mechanical Stabilized Earth (MSE) walls at all three bridges, guardrail, and fencing along the whole corridor to prevent animals from crossing the roadway. 

The existing bridge over the C-111 Canal is in deteriorated condition that required a new one at a higher profile. The two main hot items during the construction of this project are environmental issues, due to the proximity to wetlands areas on both sides of the roadway along the entire project corridor, as well as disposal of the muck material removed along the entire project corridor.

Benefits

Through this project, the area for evacuation for Florida Keys residents in case of a hurricane in the area of the Keys will be amplified, providing new bridges and wider roadway.

This was an environmental sensitive project because portions of the project are adjacent to Everglades National Park, within the boundaries of the Florida Keys National Marine Sanctuary, and located within Outstanding Florida Waters, which also means wildlife crossings.

Technical specifications

Reconstruction of the existing two-lane roadway. Provide a median barrier wall, southbound and  northbound 12 foot lanes, and acceleration/deceleration lanes.
