PennDOT is replacing the 17-span reinforced concrete T-beam Route 452 (Market Street) bridge with a new four-span, continuous prestressed box beam bridge. The new bridge will be 343 feet long, 40 feet wide and will be built on a new alignment and widened to meet current design standards. Crews will also resurface and regrade new approaches to the bridge.
The bridge was built in 1925 and rehabilitated in 1995. The current structure is 656 feet long, 32 feet wide and carries an average of 8,700 vehicles a day.
Road-Con, Inc., of West Chester, Chester County, is the general contractor on the $19,947,624 project that is financed with 80 percent federal and 20 percent state funds.
Route 452 (Market Street) will continue to remain open to traffic during construction except for two 28-day closures planned during later stages of construction. The project is scheduled to finish in fall 2019.
School Field Trip
Late last year, dozens of Marcus Hook Elementary School first-and second-graders donned hard hats and safety vests for an educational tour of PennDOT's ongoing Route 452 (Market Street) bridge replacement project in Marcus Hook Borough and Lower Chichester Township, Delaware County.
The students, joined by teachers and the school's principal, got an opportunity to walk across the newly-built section of the bridge to get a birds-eye view of the area and the Amtrak and SEPTA railroad tracks below. The kids asked questions about how bridges are constructed, what abutments and piers are, and what kind of materials are used in construction. The visit coincided with what the students were learning in class, like distinguishing between shapes and how to construct a paper bridge.
