Rehabilitation of Somerset County Bridge No. D0904, Station Road (CR 679) over Chambers Brook, Township of Branchburg
This project’s construction contract was awarded to Sparwick Contracting, Inc. on February 11, 2020. The Pre-Construction Meeting was held on April 21, 2020.
The Station Road Bridge, located north of River Road and south of Aspen Hill Road, was fully closed to vehicular, bicycle and pedestrian traffic on Tuesday, May 12, 2020 for the rehabilitation of historic County Bridge No. D0904 over Chambers Brook. The duration of this road closure is expected to be six months. Due to the close proximity of the bridge rehabilitation work, the intersection of Station Road and River Road will also need to remain closed to through traffic for this duration. The Project Location Map can be viewed here.
A detour is currently in place for the River Road over NJ Transit bridge replacement. This existing detour will be modified to reroute detour around the Station Road Bridge project, utilizing US Route 22, Readington Road (CR 637), Dreahook Road/Old York Road, and US Route 202.
[UPDATE 6-19-2020]: NJDOT's contractor has completed the work for the River Road over NJ Transit bridge replacement project. However, this new bridge cannot be reopened to through traffic until the County's Station Road Bridge project is completed as the intersection of Station Road and River Road needs to remain closed as an active work zone. The existing detour routes (cars / trucks) will remain in place.
Branchburg Township has temporarily designated Central Place and segment of River Road as a ONE-WAY roadway southbound, starting at Station Road and ending at intersection of Miller Avenue. Temporary traffic control signs and barricades are in place.
County Bridge No. D0904 carries Station Road (CR 679) over Chambers Brook in the Township of Branchburg, just north of the River Road intersection and approximately 0.5 south from the US Route 22 interchange. The existing bridge was built in 1850 and widened previously in 1935. The existing structure is a single span, brick and stone masonry arch for the original section and two rolled steel girders for the widened section. The bridge carries two lanes of traffic in each direction, for a total roadway width of approximately 30 feet.
The overall condition of this bridge structure is poor due to the poor condition of the superstructure. The stone masonry superstructure has deteriorated and displays missing mortar and outward movement of the spandrel wall.
The purpose of this project is to restore the structural capacity of the bridge by rehabilitation of the existing structure. Work includes replacing the two existing steel stringers, construction of new concrete deck, and relocation of the existing gas main. The historic stone arch and wing walls will be rehabilitated in compliance with the Secretary of Interior’s Standards for Treatment of Historic Properties. New bridge railing and guide rail will also be installed, as well as approximately 300 feet of roadway construction.
The structure is classified as Structural Deficient. The purpose of this project is to maintain and preserve the bridge and to rehabilitate the bridge from poor to good condition while retaining its historic integrity and character defining features. The work also includes installing scour countermeasures, stabilizing the embankment and improving traffic safety elements. The existing bridge width will remain the same. The proposed bridge rehabilitation will remove this bridge from the structural deficient list and provide appropriately designed scour protection.
This project is funded by NJDOT FY2017 Local Bridges Future Needs grant.
Public Information Meeting
