Hillsborough Township

Replacement of the County Bridge Nos. B0502 and B0404, Wertsville Road over Tributary to Neshanic River, Hillsborough Township

Construction Announcement

The segment of Wertsville Road, between the intersections of Long Hill Road and Montgomery Road, will be fully closed to all through traffic starting Monday October 3, 2016 for approximately 3 months. Bridge B0502 will be replaced first, then Bridge B0404 will be replaced next. A detour will be posted using Long Hill Road, Amwell Road (CR 514) and Montgomery Road. The Project Location Map with Detour Route can be viewed here.

Status Update 1/25/2017:  Both bridges along Wertsville Road were fully reopened to through traffic on Friday, December 30, 2016.  Remaining work will be completed in the Spring without a full road closure required.

Project Description - Bridge B0502

County Bridge No. B0502 carries Wertsville Road over a tributary of the Neshanic River in the Township of Hillsborough, approximately 150' west of the intersection with Long Hill Road.  The existing bridge is a single span, multi-stringers structure with concrete encased steel beams with concrete deck and concrete parapets, founded on stone abutments with adjacent concrete wingwalls.  The existing  6’-6” single span bridge provides a 16' clear roadway width, posted as a one-lane bridge carrying two-way traffic.  The existing bridge is structurally deficient due to the deterioration in both the substructure and superstructure and functionally obsolete due to inadequate deck geometry.

The purpose of this project is to restore the structural capacity of the bridge by complete replacement of the existing structure with a single span precast concrete box culvert with precast wingwalls with cast-in-place concrete parapets with textured inset panels.  The roadway will be widened to 30'  clear at the bridge to provide two 11’-0” lanes with 4’-0” shoulders.

Project Description - Bridge B0404

County Bridge No. B0404 carries Wertsville Road over a tributary of the Neshanic River in the township of Hillsborough, approximately 150 feet east of the intersection with Montgomery Road.  The existing bridge, built circa 1923, is a single span, concrete encased steel stringers with concrete deck and concrete parapets, founded on concrete abutments with adjacent concrete wingwalls.  The existing 25’-10” single span bridge provides a 20-foot clear roadway width.  The overall condition of the structure is fair due to heavy rust, lamination and minor section loss in the stringers and due to severe scaling, large spalls and wide cracks in the abutment walls.  The existing bridge is functionally obsolete due to the substandard bridge roadway width.

The purpose of this project is to restore the structural capacity of the bridge by complete replacement of the existing structure with a single span precast concrete rigid frame culvert with cast-in-place concrete wingwalls with cast-in-place concrete parapets, all with stone veneer.  The roadway will be widened to 30 feet clear at the bridge to provide two 11’-0” lanes with 4’-0” shoulders.
