South Selmon Capacity Project
The Tampa Hillsborough Expressway Authority (THEA) will increase the capacity of the existing Lee Roy Selmon Expressway to six-lanes (adding one inside lane in each direction) to help meet anticipated growth. The South Selmon Capacity Project will address current and future congestion challenges, augment roadway safety, and help keep cut-through traffic off Bayshore Boulevard and other neighborhood streets.
Project Area
The South Selmon Capacity Project area will extend 4.5 miles from west of Himes Avenue to east of Florida Avenue in Downtown Tampa. All construction will occur within THEA’s existing right-of-way.
Estimated Project Cost
The project is a $362 million investment funded entirely through THEA toll revenues. No state or federal tax dollars are being used. All revenue collected on the Selmon Expressway stays here in Tampa and Hillsborough County.
THEA reinvests toll revenues back into the system and community to fund improvements and projects like the South Selmon Capacity Project.
Tampa Bay is Growing
Living in Tampa Bay, you’ve likely noticed tremendous growth around you. It’s an exciting time for our region, and we are fortunate to live, work, and play in this place we call home.
However, while living in a flourishing community has many positives, growth brings challenges, one of which is congestion on our roadways. For example, the Lee Roy Selmon Expressway has seen an over 80% increase in traffic over the last decade. And with hundreds of thousands of new residents expected to move to the Tampa Bay region over the coming years, our mobility challenges will only continue to grow.
The South Selmon Capacity Project will address current and future congestion challenges, augment roadway safety, and help keep cut-through traffic off Bayshore Boulevard and other neighborhood streets.
THEA’S Commitment
Along with the capacity improvements, THEA will install noise walls in residential areas within the project limits, featuring an attractive brick design.
THEA is committed to improving walkability under the Selmon Expressway. This project will upgrade underpasses, including sidewalk enhancements, improved lighting, brick or stamped concrete accents by location, and fresh paint. THEA will re-engage with the community to gather input, and the Bay-To-Bay/Macdill underpass will be reimagined into a multi-use park.
Throughout the project, THEA will continue to solicit and address community input related to potential construction-related impacts.
