The Gateway Expressway design-build project will change the existing roadway system in Pinellas County in order to enhance safety, add capacity, and improve mobility by creating two new four-lane elevated tolled roadways. It was awarded to the Archer Western-de Moya JV team in the summer of 2017.

With approximately 90 miles of roadway affected by this construction, fast and accurate survey data collection was paramount to the design process. Colliers Engineering & Design was asked to support BCC Engineering on this project by providing mobile LiDAR collection for the entire proposed corridor and design survey file creation to produce topography and a digital terrain model over the entire project limits.
