Readington Road project update


Reconstruction of Readington Road (County Route 637) from Dreahook Road to Harlan School Road, Branchburg Township, Somerset County, Readington Township, Hunterdon County

Current Update:

3/28/17:  Readington Road will close after 9 AM on Wednesday March 29, 2017 for the replacement of the bridge near Baird Road and for areas of deep excavation. This will be a continuous road closure; detour routes are posted with signage along State and County Routes (see detour map below).  Road to be re-opened by July 4th.

Major construction activity will begin in March 2017 with an anticipated full road closure in mid-March 2017.  That road closure is expected to be for 3 to 4 months with a road opening occurring in late June 2017 or early July 2017.  Construction will then continue for another 1-2 months with work being performed with daytime lane closures.

The road will be open for the weekend of the Balloon Festival for the last weekend of July 2017.  Due to the shutdown on the project, the completion date will change from July 2017 to October 2017.

Project Summary

Somerset County has efforts underway to reconstruct Readington Road, CR 637, because of several operational problems contributing to numerous traffic accidents along the corridor. The goals of the road work are to make the road safer and more effective by improving intersections and adding shoulders to aid with accident avoidance and turning movements onto side streets and driveways. The improvements will address roadway deficiencies such as severe vertical curvature impacting line of sight, pavement condition, and storm runoff collection that increase the risk of motor vehicle accidents.

This project consists of the construction of approximately 1.05 miles of roadway reconstruction and associated drainage work. Curbs are to be installed along all residential properties. The proposed roadway width is 36’ wide to provide for two lanes, each 11’ wide, and two paved shoulders, 7’ wide. The roadway will widen to 41’ at the intersection of Baird Road for the addition of a left turn lane. A new traffic signal will be installed at the intersection of Baird Road.

The project will also include the replacement of County Bridge C0802 located just north of the intersection of Baird Road.


Construction is planned to start in the Summer of 2016 and continue through to Summer of 2017.
