Lee Roy Selmon Crosstown Expressway Expansion
Tampa, Florida

In areas with limited access, concrete segments were delivered over the completed portions of the elevated roadway. Maintaining traffic during construction is a benefit important to the future of expanding our national transportation corridors.Bridge technology was applied in a non-traditional manner to this congested urban corridor, resulting in bridges that utilize only 6’ of the existing median in order to add six lanes of capacity. Minimal right-of-way was required.Ridership on the elevated lanes have exceeded projections and significantly reduced congestion and commute times between eastern suburbs and Tampa, on both the tolled expressway and parallel US 60. Commuters’ drive time has been reduced by more than 50%.

Traditional expansion of U.S. 60—which connects Tampa, Florida, to its rapidly growing eastern suburbs—was not financially feasible. The designers decided to build up rather than out by utilizing the existing expressway median to house a three-lane elevated structure. After the opening of the elevated lanes, average trip times were reduced 20 to 30 minutes during the morning commute for both the elevated lanes and existing Expressway toll lanes. Additionally, after the initial opening of the elevated lanes, average daily traffic actually increased—although travel time remained efficient and decreased. The unique shape of the superstructure concrete box, coupled with the graceful shape of the supporting piers, provide the Expressway at-grade lane drivers with a premium visual experience.
