County Route 535 (CR 535) is a county highway in the U.S. state of New Jersey. The highway extends from Logan Avenue (where it becomes CR 635), at the boundary between Trenton and Hamilton Township in Mercer County to an interchange with U.S. Route 9 (US 9) and Route 35 in South Amboy, Middlesex County. The road serves as the main street through the communities of Cranbury, South River and Sayreville, while also passing through rural areas on the outskirts of Mercer and southern Middlesex counties. At various points, it is locally known as East State Street, Edinburg Road, Old Trenton Road, Cranbury-South River Road, Main Street, Washington Road, and Raritan Street. Route description The designation of CR 535 picks up East State Street at the Trenton city line and heads northeast into the Bromley neighborhood of Hamilton. It parallels the Northeast Corridor line between both municipalities' respective train stations before abruptly turning southeast at , an intersection with Klockner Road. Now the East State Street Extension and maintained by Hamilton Township, CR 535 meets Interstate 295 (I-295) with limited access at exit 64. Traffic traveling southbound on CR 535 (traveling geographically north for this brief stretch) has a ramp leading to I-295 north toward US 1, while southbound traffic on the freeway can exit onto CR 535 north. From here, CR 535 continues toward Nottingham Way (CR 652), and turns left onto it, about east of where Route 33 merges onto Nottingham Way. County maintenance resumes at this point and CR 535 stays on this road for just before reaching a five-way intersection with Route 533 (Quakerbridge Road north of the intersection, White Horse-Mercerville Road south of it) and Nottingham Way, which is CR 618 as it travels southeast away from the intersection toward Hamilton Square. Having regained its northeast direction, CR 535 moves through this intersection and becomes Edinburg Road. At a traffic signal with Paxson Avenue, the road widens to two lanes in each direction. It leaves Hamilton for West Windsor, and bumps up against Mercer County Community College on the left. Just beyond the college is Mercer County Park, which is accessible through South Post Road (CR 602) or through the park's official west entrance after CR 535's reduction to one lane each way. Just beyond the park entrance, the route has a short concurrency with CR 526, which comes from Robbinsville Township to the south.
