This FDOT District One design project includes reconstruction of the Interstate 75 (I-75) at Bee Ridge Road interchange in Sarasota County. The Department will rebuild the interchange from the existing diamond design to a hybrid diverging diamond interchange (DDI) and southbound diversion ramp. The Department will also rebuild the Bee Ridge Road at Cattlemen Road intersection to a continuous flow intersection (CFI).
The hybrid DDI, southbound diversion ramp, and CFI work in conjunction to accommodate the traffic at the I-75/Bee Ridge Road interchange and the Bee Ridge Road/Cattlemen Road intersection, which are in very close proximity to each other. The hybrid DDI shifts eastbound traffic to the left to allow for improved access to northbound I-75. The southbound diversion ramp eliminates a weaving issue between the I-75/Bee Ridge Road interchange and the Bee Ridge Road/Cattlemen Road intersection. It also improves access to commercial and residential areas on or near Cattlemen Road. The CFI diverts the westbound and eastbound traffic to the left prior to the intersection. This reduces the number of phases for the signals and improves delay times.
The project will widen about 3.8 miles of I-75, from south of Bee Ridge Road to south of Fruitville Road, to an eight-lane highway with three through lanes and one auxiliary lane in each direction added to the interstate median. This project will widen I-75 bridges over Palmer Boulevard and Phillippi Creek and replace I-75 bridges over Bee Ridge Road. The project also includes widening about one mile of Bee Ridge Road from west of Bee Ridge Road/Maxfield Drive intersection to west of Bee Ridge Road/Mauna Loa Boulevard intersection.
A future ultimate I-75 design project will widen the interstate from interim eight lanes to twelve lanes. The project includes two express lanes, three general use lanes, and one auxiliary lane in each direction within the project limits. Ultimate improvements are planned to extend acceptable level of service for I-75 well beyond 2050.
