FDOT further announces that the C.R. 484 on ramp to northbound I-75 will be closed nightly from 8 p.m. to 6 a.m. on Tuesday and Wednesday, March 18 and 19.

What’s with the closures?

FDOT reports that the closures will allow a project to resurface I-75 from the Sumter County line to S.R. 200, reconstruct existing median crossovers, add and update guardrails, and maintain nearby drainage.

This first project, labeled 443170-1, reportedly began in early 2023 and will finish this Spring. Its cost is estimated at $28.4 million.

FDOT says a second project, 433651-1, is underway in association with the first project. This second project will see additional turn lanes and extensions at the C.R. 484/I-75 interchange and the C.R. 484/C.R. 475A intersection. The westbound through lanes will be reconstructed, and the existing I-75 bridge will be modified to accommodate the widening.

In addition, FDOT promises improvements to bicycle lanes and pedestrian sidewalks, modifications to medians and upgrades to the existing traffic signals.

The second project began in early 2023 and is slated for completion this Fall. The cost of the project is estimated at $11.6 million
