Project Detour Plan

Project Area Description

River Road (CR 567) is located in the Township of Hillsborough in Somerset County. It is a north-south Urban Major Collector extending from Amwell Road at the south to Pleasant Run Road at the north, ultimately providing access to US Route 202.  The existing roadway width is substandard, and the pavement is in poor condition due to the ongoing erosion along the South Branch Raritan River. 

This project includes roadway improvements along the section of River Road that begin approximately 100-feet north of the intersection with Elm and Mill Streets and extend north 625 feet under the railroad bridge.  River Road will be widened from 22-foot to 28-foot in total width, reconstructing most of the pavement within the project limits.  A retaining wall will be constructed along the southbound lane to alleviate embankment erosion issues between the road and the South Branch Raritan River.  Additional improvements include a new 4-foot wide berm between the wall, replacement of guide rail, fencing along portions of the new wall, drainage improvements, new pipe outfalls and erosion protection measures at the river.
