WESLEY CHAPEL, FL. – The southbound I-75 Exit 275 ramp to SR 56 may be closed from 9 p.m. to 5 a.m. Sunday through Friday nights (April 25 – 30), weather permitting.
Detour Route to SR 56: Use Exit 279 to SR 54/CR 54. At the bottom of the ramp, turn left and go east on SR 54. Turn right onto SR 581 (Bruce B. Downs Boulevard) and go south to SR 56.
This project will reconfigure the I-75/SR 56 interchange between CR 54 and Cypress Ridge Boulevard in Pasco County. The existing diamond interchange will be modified and converted to a diverging diamond interchange (DDI). The main change will be to diverge (cross) SR 56 traffic to the left side of the road through the interchange, and then cross vehicles back over to the right side of the road on the opposite side of the interchange. The changes will help to alleviate traffic congestion at this interchange to reduce travel time for motorists in this rapidly growing area.
The contractor anticipates completing the project in the late 2021. This estimate does not include weather or other unanticipated delays.
A DDI was chosen for the I-75 / SR 56 interchange because of the proven ability of this traffic configuration to increase safety and capacity while using a large amount of the existing interchange footprint, including the existing bridge. The DDI was also chosen because of its ability to handle heavy left turn volumes, such as the westbound to southbound movement from SR 56 to SB I-75.
The expected benefits for the interchange are an increase in capacity and pedestrian safety while reducing vehicle delays and crashes. These benefits will be achieved by an increased number of lanes, improved pedestrian facilities, more efficient signal timings, and reduced vehicle conflict points.
