About the Project

Picture of the I-75 at SR 951 Intersection.


In 2014, the Florida Department of Transportation (FDOT) completed the federally required Project Development & Environment, or PD&E, Study to evaluate improvements to the I-75 at SR 951 (Collier Boulevard) interchange. Several interchange design alternatives were developed and evaluated as part of this study. An extensive public involvement program was implemented to inform the public of the study and to receive feedback on the proposed improvements being considered.

With Federal Highway Administration's approval of the PD&E Study, the next step in the design process is preparation of design plans that contractors will use to construct the interchange improvements.

View final documents from the PD&E Study.


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.
