US 41/SR 54 Interchange PD&E Study

RS&H is completing a project development and environmental (PD&E) study for the US 41/SR 54 interchange. The study is evaluating different interchange configurations at this extremely congested major intersection in southern Pasco County. This unique project is included in the local Long-Range Transportation Plan even though it is a stand-alone interchange that is not on a limited-access freeway.

The project has several complicating factors, including connection to an evacuation route (SR 54), a major Florida Progress substation, an active railroad crossing, a fire station, and potential braided ramps and flyovers at Dale Mabry apex to the south.

The project initially evaluated overpass configurations while also accommodating the proposed addition of managed lanes along SR 54. However, during the study, the focus of the project changed to evaluating tolled and non-tolled options for the proposed overpass and these options were presented to the public. The team developed alternatives for the overpass lanes that could be tolled or left as non-tolled and provided two general purpose through lanes at the intersection.

RS&H’s previous experience strengthened the working relationship with stakeholders and provided insight as the team developed managed lanes alternatives.
