The SR 0038 Bridge over Connoquenessing Creek was a 76-foot-long concrete T-beam bridge deemed structurally deficient by the Pennsylvania Department of Transportation (PennDOT). Because of noticeable surface erosion and deterioration, and foundational issues caused by heavy traffic volume and faulty drainage, PennDOT decided to replace the defective bridge. They turned to RETTEW to design the replacement, since we had successfully completed a similar bridge project for this particular PennDOT District well ahead of schedule.
The scope of this project included preliminary engineering, final design, and construction consultation. To start, our bridge engineers designed a single-span steel-girder replacement structure to support the 7,000 vehicles per day that traverse this bridge. We also provided wingwall and drainage design to minimize erosion and maximize the structure’s longevity, and upgraded guiderails with proper end treatments. RETTEW used a half-width construction method with temporary traffic lights to lessen the impact on local commuters.
