In 2015, CFX, FDOT and FTE announced a $68.5 million project to make several improvements to I-75's interchange with SR 44 (exit 329) and the adjoining interchange with Florida's Turnpike (exit 328). This included adding a collector-distributor ramp in each direction along I-75 leading to the interchange northbound, and leading from SR 44 to the southbound Turnpike, as well as widening I-75 to 6 lanes in each direction leading to the interchange, and adding another access point from the northbound Turnpike to SR 44 (exit 307). The project, which was handled by Middlesex Construction, began construction in September 2016. The new northbound off-ramp to SR 44 was completed on September 19, 2019, and the new southbound on-ramps to the Turnpike and I-75 were completed in early November 2019. The project overall was completed in January 2020.
