Mercer County together with Middlesex County is moving forward with the plans to replace Bridge No. 860.1, which carries Millstone Road over the Millstone River. The contract was awarded to Marbro Construction on September 12, 2013. The project is anticipated to start December 9, 2013, with an anticipated completion time of approximately six (6) months, weather permitting.
During this time, Millstone Road at the bridge would need to be completely closed and it will be necessary to detour traffic. Motorists will be directed to use Old Trenton Road, Southfield Drive/Nostrand Drive and Cranbury Neck Road. Millstone Road/John White Road will be open to local traffic up to the construction site. Project notification signs will be installed in the vicinity of the construction one (1) week prior to commencement of construction.
Old Trenton Road (County Route 535)
On or about Monday, October 14, 2013, storm sewer pipe and surface repairs are expected to commence on Old Trenton Road from Princeton-Hightstown Road to Mercer County Bridge 860.2 over the Millstone River (between One Mile Road and Ancil Davidson Road). Mercer County anticipates that this work will take approximately ten (10) working days, weather permitting. Construction would take place from approximately 9:00 a.m. to 3:30 p.m., weekdays only.
Construction would be completed in the following sequence:
1. The County's contractor, Waters and Bugbee, would begin repairs to the storm sewer pipe. Repairs to the storm sewer pipe are expected to require approximately one week to complete, and would occur simultaneously with milling and paving operations. However, commencement of this work is contingent on availability of materials. The contractor's representative believes their work could start Monday, October 14. During this time, traffic would be maintained on Old Trenton Road.
2. Tuesday, October 15, Old Trenton Road would be milled from Mercer County Bridge 860.2 over the Millstone River, located immediately south of Ancil Davidson Road, through the intersection of One Mile Road. During that time, traffic would be permitted through the work area but controlled by police.
3. This section of Old Trenton Road would be paved and then opened to traffic in the same day. Please note that during paving operations, the intersection of One Mile Road and Old Trenton Road would need to be closed for a short period of time.
4. Old Trenton Road immediately south of One Mile Road and Princeton-Hightstown Road would then be milled and paved. During that time, Old Trenton Road will be closed to through traffic. However, the road would remain accessible to local residents, businesses and emergency services. Northbound through traffic would be detoured left onto Princeton-Hightstown Road, right onto Southfield Drive and right onto Cranbury Neck Road. Southbound traffic would be detoured left onto One Mile Road, and right onto Princeton-Hightstown Road.
Van Kirk Road over Shipetaukin Creek
On or about Monday, October 21, 2013, bridge repairs are scheduled to commence on the Van Kirk Road Bridge (#543.9) over the Shipetaukin Creek. Anticipated duration of this project is approximately three (3) months, weather permitting. During this time, it will be necessary to close the bridge to all traffic on a 24/7 basis and through traffic will be directed to use Cold Soil Road. However, Van Kirk Road on either side of the bridge will remain open for local use. Mercer County will install signs advising motorists of upcoming bridge repairs and detours.
On or about July 15, 2013, the bridge carrying Old Trenton Road (Bridge No. 740.2) over Assunpink Creek will be closed for reconstruction, with construction expected to be completed by December (construction duration 135 calendar days), weather permitting. The bridge is located between Robbinsville-Edinburg Road (CR 526) and Edinburg Road/Windsor Road (CR 641). 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.
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. 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.
