Temporary detour begins Feb. 9

A temporary roadway has been installed at SW 49th Ave & SW 66th St to maintain traffic flow during the construction of the middle and eastern portions of the intersection. The temporary roadway will create a smooth, 90-degree transition from SW 49th Ave Road onto SW 66th St, westbound toward State Road 200.

The bridge over I-75 will remain open during phase 1. Motorists wishing to cross the bridge will be required to use SW 38th Ave., which is runs parallel to I-75. Electronic messaging boards have been places as indicated in the above image by red boxes.

SW 49th Avenue Roadway Improvements

SW 49th Avenue has long served as a key north-south corridor west of I-75. Once a two-lane rural road without sidewalks, it now requires expansion to meet future traffic demands. Studies show that without improvements, the roadway’s service level would fall to failing by 2040.

The project is being completed in phases:

• North phase: Converts the roadway from Marion Oaks Trail to SW 95th Street into a four-lane divided road.

• South phase: Expands the roadway from County Road 484 to SW 128th Street into a four-lane divided road with wider lanes, bike lanes in each direction, and a raised median with turn lanes.

• New connection: Builds a four-lane divided roadway from SW 95th Street to the SW 42nd Street flyover, easing congestion on I-75 and surrounding roads while improving emergency response times and safety for nearby schools, neighborhoods, and the Cross-Florida Greenway.

Behind the scenes, the project also includes more than 9,000 feet of new stormwater piping to ensure proper drainage and protect both the roadway and surrounding properties.

Funded in part by the Penny Sales Tax, construction began earlier this year, with a ribbon cutting expected by spring 2026.
