Road Closures for I-75/Collier Boulevard Interchange Project

Motorists are encountering multiple roadway closures during January as workers complete the overhead work that is part of the reconstruction of the I-75 – Collier Boulevard interchange.

State Route 84-Davis Boulevard is closed from Market Street to Collier Boulevard-S.R. 951 through January 16, requiring drivers to use Market Street and Business Circle S instead.

In addition, the southbound I-75 on-ramp from northbound Collier Boulevard (S.R. 951) is closed during the nighttime-overnight hours through January 16. Drivers must travel southbound on Collier Boulevard to access the ramp. That requires traveling northbound on Collier to the intersection of Magnolia Pond Road and City Gate Boulevard. Drivers can then make a U-turn and head south on Collier to access the southbound on-ramp immediately after the I-75 overpass by making a left turn.

Travelers will also encounter:

• Lane shifts on Collier Boulevard-S.R. 951 from Business Circle South to I-75 to create work zones for crews.
• Closure of the outside right turn lane from southbound S.R. 951 to westbound S.R. 84-Davis Boulevard. Drivers can turn right from the remaining open turn lane. This closure will remain in place through job completion.
• For pedestrians, a sidewalk closure along S.R. 84-Davis Boulevard just west of Collier, and along Collier, between S.R. 84-Davis Boulevard and Business Circle North. Pedestrians can use S.R. 84-Davis Boulevard to Market Street, to Business Circle South to access S. Collier Boulevard-S.R. 951.

The S.R. 84-Davis Boulevard eastbound direct access ramp heading south to Collier is permanently closed. The eastbound to southbound right turn is available at the intersection. And the lane widths for southbound Collier between Business Circle North and Business Circle South have been reduced.

Plans call for the project to be completed by year’s end.

FDOT is rebuilding the southbound on-and off-ramp connectors and the northbound on-ramp connector at I-75’s Exit 101 to create additional space for a single-lane, 200-foot radius loop ramps. The northeast quadrant loop ramp will connect to and only be accessible by a single-lane, flyover ramp from northbound Collier Boulevard (S.R. 951), starting south of the intersection with Davis Boulevard.

That flyover ramp will carry traffic over Beck Boulevard and the I-75 southbound on-ramp. A single-lane flyover ramp extension will carry I-75 southbound traffic over Davis Boulevard to a new signalized intersection at Collier Boulevard and Business Circle North. This ramp will extend along the western side of Collier.

Work on the $97 million project began in early 2023.

FDOT officials say the project’s purpose is to improve operations and traffic flow at the interchange area, which includes the intersection of Collier Boulevard and Davis and Beck Boulevards. The end result will enable local commuter traffic to be separated from motorists heading south of Davis, such as people heading to and from Marco Island, and drivers who are coming or going from destinations off I-75, north of the interchange.

FDOT asks motorists to please use caution and watch for workers and construction vehicles entering and leaving the roadway. For more information, please visit: https://www.swflroads.com/project/425843-2
