TRENTON, N.J. - The bridge carrying Old Trenton Road over Assunpink Creek in West Windsor will be closed for reconstruction beginning July 15, with construction expected to be completed by December (construction duration 135 calendar days), weather permitting. The bridge is located between Robbinsville-Edinburg Road (County Route 526) and Edinburg Road/Windsor Road (County Route 641).
The existing bridge was built in 1927 and has been deemed structurally deficient, with a sufficiency rating of 30.0 out of 100. Ratings reflect deteriorated conditions of the structural components.
“West Windsor is a flourishing community that looks quite different today than when this bridge was built 86 years ago,” said Mercer County Executive Brian M. Hughes. “Under Mayor Shing-Fu Hseuh’s leadership, West Windsor continues to draw families and businesses looking for a strong community in which to grow roots.”
The project will consist of complete demolition and removal of the existing concrete bridge. The replacement structure is a single span bridge, composed of composite steel stingers supporting a reinforced concrete deck. The new, widened bridge will have two 11-foot-wide through lanes, a 10-foot-wide center turn slot, two 6-foot shoulders, and a 6-foot sidewalk on the north side of the bridge.
The existing traffic signal at the intersection of Edinburg Road/Windsor Road and Old Trenton Road will be upgraded. Also, a new traffic signal will be installed at the Robbinsville-Edinburg Road intersection with Old Trenton Road. A left-turn slot will be provided onto both Edinburg Road and Robbinsville-Edinburg Road, thus reducing traffic back-ups during peak periods.
Mayor Shing-Fu Hsueh stated, “We are grateful to County Executive Brian Hughes and the Board of Chosen Freeholders for funding this project that not only replaces a deficient bridge but also addresses traffic problems through this quiet West Windsor village.”
Construction will require that the entire bridge be closed for the duration of the project. The posted detour route for westbound traffic will make use of Windsor Road (CR 641) to State Route 130 to State Route 33 to Robbinsville-Edinburg Road (CR 526). Eastbound traffic will be directed to use the reverse route.
Added Hughes, “Let me in advance thank the community for their patience and cooperation while this project is under way. We always try to work as quickly as possible and hope that the weather cooperates.”
The Mercer County Board of Chosen Freeholders approved the award of bid to Lucas Construction Group of Morganville on May 21, 2013. The cost of the project is $2,138,588.11 and will be funded through the annual transportation programs from the New Jersey Department of Transportation Division of Local Aid.
In addition to this project, a bridge replacement project on Princeton-Hightstown Road (Bridge No. 762.7) started in March 2013, and is a 270-calendar-day project with an anticipated completion of December 2013, weather permitting. The contractor is Lucas Construction Group of Morganville, and the contract amount is $3,189,622.47.
Replacement of this structure was deemed necessary due to substantial deterioration of critical structural members and poor deck condition. This bridge replacement project is being staged so that one lane of traffic in each direction will be maintained. The contract duration of 270 calendar days, weather permitting, is largely due to the need to do phased construction and maintain traffic on Princeton-Hightstown Road.
