PennDOT Completes Route 926 Bridge Rehabilitation Project
On Friday, August 25, 2017, PennDOT joined elected officials to celebrate the opening of the newly built bridge carrying Route 926 (Street Road) over the Brandywine Creek in Birmingham and Pocopson townships, Chester County.
“The completion of this new bridge will help boost local economies and bring enormous benefits to thousands of motorists, cyclists and pedestrians on both sides of Brandywine Creek by providing safer and more reliable travel,” PennDOT Assistant District Executive for Construction George Dunheimer said.
PennDOT improved Route 926 (Street Road) by replacing the 79-year-old bridge with a new three-span structure built at a higher elevation; rebuilt and raised 1,700 feet of the roadway approaches to make them less prone to flooding; replaced the nearby culvert over Radley Run with an 84-foot twin arch concrete culvert; and realigned 800 feet of Creek Road at its northern intersection with Route 926 (Street Road).
The new, aesthetically designed bridge resembles the current structure and has stone form liners covering the piers, and includes an open, higher railing.
The previous four-span Route 926 (Street Road) bridge was built in 1937 and rehabilitated in 1974. The steel I-beam structure was 190 feet long and 26 feet wide. Before it closed for construction, the bridge was posted with a weight restriction of 26 tons and 33 tons for combination loads and carried approximately 13,200 vehicles a day.
As part of this project, PennDOT’s contractor activated a new traffic signal in February that included a Flashing Yellow Arrow signal for left turns from Route 52 (Lenape Road) to Pocopson Road/West Chester Road, in addition to the standard red, yellow and green lights. This Flashing Yellow Arrow signal was the first to operate in the Philadelphia region.
The new traffic signal has enhanced traffic flow on Route 52 (Lenape Road), which was part of the project detour and carried heavier traffic volumes during the Route 926 (Street Road) closure.
