Interstate 76 (I-76), or the Schuylkill Expressway, is one of the busiest roads in the state. With the approximately 120,000 daily drivers traveling around Philadelphia and Montgomery County on this major highway, safety is paramount. Pennsylvania Department of Transportation’s Engineering District 6-0 wanted to evaluate all the bridges in the county along this corridor. That’s more than 20 bridges in all from King of Prussia to Philadelphia that may need work.
District 6-0 contracted with RETTEW on this $5 million agreement. The first phase is to evaluate eight mainline structures; develop an alternatives analyses for preservation, rehabilitation, or replacement of the superstructures; and prepare a recommendation report. Subsequent phases will include preliminary design, final design, and construction consultation. The purpose of the project is to extend the life of these structures by specifying rehabilitations of the existing structures along with designing preventative maintenance measures. This project will help avoid the need to replace the structures entirely, which will save costs and minimize impacts to the traveling public in the Philadelphia area.
