Replacement of County Bridge E1310, Branch Road over Tributary to North Branch Raritan River, Borough of Peapack Gladstone
UPDATE (8-14-2017): Branch Road was fully closed to through traffic starting on Monday, August 14, 2017. Construction is expected to completed by mid-October. A posted detour will be in place during construction utilizing Willow Avenue, Main Street (CR 512), Mendham Road (CR 647) and Mosle Road. Local access will still be maintained via Mosle Road / Hub Hollow Road at the north end of Branch Road.

Somerset County Bridge No. E1310, located in the Borough of Peapack and Gladstone, carries Branch Road over a Tributary to North Branch of Raritan River, at the southern end of Branch Road near the intersection of Willow Avenue. The existing bridge consists of twin 5’-0” diameter corrugated metal pipes, providing a 22’-0” roadway width with two travel lanes and no shoulders. The existing bridge is in “poor” condition due to rusting of the corrugated metal pipes and the loose and fallen stones of the headwalls. Average daily traffic of the rural local Branch Road in 2009 was 260 vehicles daily.
The purpose of this project is to replace the existing bridge and to provide two 11’-0” lanes with 2’-0” shoulders at the bridge to improve the safety of motorists and pedestrians. The proposed bridge will be a precast concrete three-sided rigid frame with concrete wingwalls and parapet. Stone veneer is proposed for the parapets. Beam guide rail and end terminals will follow current standards at all approach and trailing corners of the bridge.
A realignment of the south approach is being proposed to stabilize the west embankment of roadway due to erosion of the stream bank. The south approach is proposed to be shifted a maximum of 7’-0” to the east.
