Prestressed Concrete Beams (total of 5, approx. 53.5 ft. long each) were installed for the small bridge (Structure No. F09-25) on July 7, 2021 (looking east along Gas House Pike across F09-25).
All 5 prestressed concrete beams (July 7, 2021 installed) for Structure No. F09-25. Looking northeast under structure at existing ground level.
Superstructure reinforcement steel was completed for Structure No. F09-25 and concrete deck placement occurred on September 8, 2021. Concrete pumping truck placed concrete for the superstructure deck. Bidwell machine (in background) is finishing the placed concrete to meet designed deck elevations.
Screed on the Bidwell machine is bringing the placed concrete to finished elevation on the bridge deck for Structure No. F09-25 (performed on September 8, 2021).
Beam #5, the last of 5 prestressed concrete beams, was installed for the large bridge (Structure No. F09-21) on August 2, 2021 (looking northeast along Gas House Pike at the west abutment side).
Aesthetics on the bridge parapets were part of the design. Photograph is of the completed stained, formliner finish on Structure No. F09-25 (52-foot span, smaller bridge). A formliner pattern was used during concrete parapet installation on both bridges to simulate large, river rocks as the concrete finish.
Photograph is of the completion of two new bridges, Structures Nos. F09-25 and F09-21, new roadway approaches and roadway tie-in sections, just prior to the re-opening of the road on December 15, 2021. Roadway pavement markings and required guardrail were also necessary to be installed before the road re-opened to traffic.
