FDOT is currently designing improvements to Interstate 75 (I-75) at the SR 951 (Collier Boulevard) interchange in Collier County.  The proposed improvements for the I-75 at SR 951 (Collier Boulevard) interchange include reconstruction of the I-75 southbound on- and off-ramp connections and the northbound on-ramp connection to the mainline lanes. The southbound and northbound off-ramps will be reconstructed to create additional infield space to install single-lane, 200-foot radius loop ramps in the southwest and northeast quadrants.

The northeast quadrant loop ramp will be connected to, and accessible only by, a direct flyover ramp from northbound Collier Boulevard with a starting point south of the Davis Boulevard intersection. This single-lane flyover ramp will carry traffic over Beck Boulevard and a reconstructed 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 Boulevard.
