South Selmon PD&E Study

Project Description

The Tampa Hillsborough Expressway Authority (THEA) is conducting a Project Development and Environment (PD&E) Study to evaluate capacity improvements along the southernmost section of Selmon Expressway. The study limits extend from the eastern project limit of the Selmon Expressway West Extension Project to the beginning of the six-lane section near the overpass at Whiting Street, a distance of approximately 4.5 miles. Various roadway and ramp improvements will be evaluated during the study to improve the efficiency and capacity of the Selmon Expressway well into the future. It is anticipated that the improvements will primarily be accommodated within existing right-of-way.

Travel time reliability is important to our customers. We are looking at ways to reduce travel times during the morning and evening rush.
One of the primary goals of this study is to identify solutions to the frequent congestion at entry and exit points along the Selmon Expressway.
The Study will evaluate strategies to eliminate conflict points and reduce crashes.
Reduced congestion and improved safety coupled with the Selmon Extension Project will enhance east-west mobility for the region.
Hillsborough County’s population is projected to increase 38% by 2045.
