Bridge replacement of Delaware County Bridge No. 73 over Darby Creek, State Route 7023, Section 073
This project was for the replacement of the Rosemont Avenue Bridge over Darby Creek with construction of a single span, composite pre-stressed concrete spread box beam bridge on spread footings. Clearwater Construction replaced the existing plate girder pony truss bridge carrying Rosemont Avenue over Darby Creek with a single span, composite prestressed concrete spread box beam bridge including architectural treatments and a new bronze bridge plaque to preserve the aesthetics of the previous structure.
Improvements include a new roadway alignment and a wider deck section to allow for improved site distance and increased traffic flow. While a sidewalk on one side of the structure with ADA curb ramps will enhance pedestrian safety, utility relocation was required to accommodate the new structure and included pre-planning for future gas line transport under and across the bridge approaches and span.
This project was completed 8 months ahead of schedule.
