SW 66th Street Bridge Over I-75 Being Replaced: Detours and Lane Closures in Ocala
This is a community news article published on 2026-09-30 covering local Marion County, Florida news. FDOT began demolishing the SW 66th Street overpass at I-75 on Sept. 21. Drivers should use the SW 43rd Street Road bridge and expect overnight northbound lane closures.
Detour: Use SW 43rd Street Road
Drivers who normally cross I-75 on SW 66th Street must use the SW 43rd Street Road bridge instead, which can add time to commutes in the area. Southwest Ocala residents heading to the shopping and dining corridors along SW College Road and SR 200 should plan a few extra minutes.
Overnight Lane Closures on Northbound I-75
During demolition, northbound I-75 lanes are closed overnight from 10 p.m. to 6 a.m. Traffic merges from three lanes down to one, and the speed limit is reduced to 60 mph approaching the work zone. The original schedule called for closures through Thursday, Sept. 24, resuming the following Sunday night if the work was not finished. Crews told WCJB they could not give a completion estimate for the demolition phase.
Why the Bridge Is Being Replaced
The overpass has been struck repeatedly by tall vehicles. FDOT District 5 spokesperson Cindi Lane said the bridge "has experienced some bridge hits over the years," including semi-trucks carrying oversized loads and dump trucks with raised beds. The new bridge will be about five feet taller and wider than the old one.
Part of the Larger I-75 Widening
The bridge work belongs to a broader FDOT project that is widening I-75 lanes from Wildwood to State Road 326 in northern Marion County. Expect more lane shifts and overnight closures along the corridor as the project advances.
Where to Check Current Conditions
Closure dates can change with weather and progress. Check FDOT's CFLRoads traffic advisories or dial 511 before you travel, especially overnight. For airport and travel planning around Ocala, see our closest airport guide.
