For several miles it forms the northern border of Warren Township with Bernards Township, both in Somerset County. It joins the Passaic just north of Exit 36 of I-78, and the junction was moved northward, away from the Exit, to allow enough room for the exit ramps. There the river is crossed by King George Road. At the next I-78 westward, Exit 33, the river is crossed by the Martinsville-Liberty Corner Road, and there is extensive commercial development in both Warren and Bernards north of the Exit and south of the river
