Replacement of Bridge No. G0701 South Main Street (CR 533)
Borough of Manville
Somerset County Bridge G0701 on South Main Street (CR 533), located between Roosevelt Avenue/Kyle Street and Kennedy Boulevard, will be under construction for the next 18 months. The new bridge will be reconstructed in three (3) separate stages, with through vehicular and pedestrian traffic and local business access maintained throughout the project.
Starting Thursday, February 2, 2017, Stage 1 traffic control was implemented. Traffic heading southbound on Main Street was shifted slightly to the east to allow for the demolition and replacement of the western portion of the existing bridge. Left turn lanes were temporarily eliminated; motorists should follow the posted signs.
On Thursday, October 19, 2017, Stage 2 traffic control was implemented. Traffic heading southbound on Main Street was shifted to the west onto the newly constructed western portion of the new bridge. This allowed for the demolition and replacement of the center portion of the existing bridge. Due to the severe winter weather, the project was ordered shut down between January 15 and April 9, 2018. Stage 2 work resumed on April 10, 2018.
UPDATE (5-11-2018): On Friday, May 11th, Stage 3 traffic control was implemented. Traffic heading northbound on Main Street is now shifted to the west onto the newly constructed center portion of the new bridge. This will allow for the demolition and replacement of the remaining eastern portion of the existing bridge. The project is currently on-track for completion of all staged roadway work by October 31, 2018.
A full road closure at the bridge with a posted detour will be implemented over approximately 10 evenings between the hours of 9 p.m. and 6 a.m. at various times during construction. A number of overhead and underground utility relocations at and adjacent to the project limits also will be performed during construction.
The County will provide updates during construction to provide advance notice for the various staged traffic shifts and nighttime detour schedules.

County Bridge No. G0701 carries South Main Street (CR533) over Royce Brook in the Borough of Manville. The existing bridge is two-span simply supported concrete encased steel stringers and one prestressed concrete box beam superstructure on concrete pier and abutments. The existing 59’-8” two- span bridge provides a 46’-4” clear roadway width with sidewalks on both sides. The substructure is in fair condition due to scaling and cracks with efflorescence at the pier and both abutments. The superstructure is in fair to poor condition due to spalled concrete encasement with exposed rusted reinforcing steel, stringers with section loss, and multiple areas of deck deterioration. The bridge is currently classified as functionally obsolete due to the inadequate deck geometry; in addition, the structure sufficiency rating is less than 50. Structural repairs continue to be required.
The purpose of this project is to restore the structural capacity of the bridge by complete replacement of the existing structure with a two-span, multi-stringers with concrete deck superstructure supported on concrete pier and abutments. To improve the functionally obsolete classification, the County is providing a 46’-4” clear roadway width to match the existing approach roadway and providing two 8’-0” wide sidewalks across the bridge.
