County Route 509 (New Jersey)
County Route 509 (CR 509) is a county highway in the U.S. state of New Jersey. The highway exists in two segments– one unsigned segment exists in northern Middlesex County while the signed mainline extends from North Avenue (Route 28) in Westfield to Straight Street (CR 504) in Paterson. For two small stretches – in Clifton at the interchange with Route 19, and in Paterson as it crosses over the Passaic River – CR 509 splits into separate northbound and southbound alignments. CR 509 intersects with the Garden State Parkway at exit 138 in Kenilworth and again  at exit 148 in Bloomfield. Route description. The unsigned Middlesex County segment begins at the intersection of Park Avenue (CR 531) and Maple Avenue (CR 602) in South Plainfield. The county route, not signed as CR 509 but rather CR 602, heads northeast on Maple Avenue through a residential neighborhood. After crossing Woodland Avenue, the road enters Edison and passes between two parts of the Plainfield Country Club. CR 602 breaks off the road at Inman Avenue leaving CR 509 on Old Raritan Road continuing northeast on a locally maintained road. At the Union County line, the CR 509 designation  ends and Raritan Road continues into Scotch Plains. The signed mainline portion of CR 509 begins at a complex intersection in the town of Westfield, west of Elizabeth. State Route 28 (South Avenue) and Union County Route 610 (North Avenue) come from Scotch Plains to the west on either side of the train tracks running along New Jersey Transit's Raritan Valley Line and criss-cross at a traffic circle a few hundred feet from the Westfield Train Station. CR 509 (East Broad Street) branches off in a northeast direction from Route 28 just after the state highway branches off  of the circle and crosses under the tracks before continuing east. From its southern terminus to Elmer Street in Westfield, the road is town maintained. After cutting through downtown Westfield, CR 509 passes Fairview Cemetery on the right before coming to an intersection with CR 577 (Springfield Avenue), which splits off to the left before banking due north toward Mountainside, Springfield and U.S. Route 22 (US 22). CR 509 turns right onto Springfield Avenue but quickly becomes Kenilworth Boulevard. For less than a mile, the route passes through Cranford, during which time County Route 615 splits off to the right . It crosses into Kenilworth, where it is signed simply as "Boulevard" while traveling nearly due east. (East Broad Street continues straight as Nomahegan Drive for less than a mile before coming to a dead end). Once through downtown Kenilworth, CR 509 interchanges the Garden State Parkway at Exit 138 before crossing into Union. It dips southeast for a few hundred feet, then turns left onto Salem Road at a five-point intersection with Union County routes 616 (Galloping Hill Road, bound for Roselle Park) and 619 (Chesnut Street, running between Linden and Irvington in Essex County). Salem Road slowly bends  back to the north, crossing State Route 82 near Kean University and over the Elizabeth River into Hillside, where it passes Vaux Hall Road and Hillside High School. CR 509 passes under US 22, but has no interchange. Traffic looking to access US 22 must turn right just beyond the overpass at Hillside Avenue, where access is provided near the Newark border. CR 509 turns left onto Hillside Avenue, while the road (now Liberty Road) continues to a dead end at St. Peter's Park on the outskirts of Newark. After turning, CR 509 makes another quick turn, this time  onto Chestnut Avenue. It passes over Interstate 78 (again with no interchange), to which access is available via Paine Avenue. The route continues as Coit Street, then Grove Street as it moves into Irvington and Essex County. Now in a heavily populated neighborhood, CR 509 crosses Springfield Avenue a little east of the end of the State Route 124 designation, and crosses several 600-series routes while closely paralleling the Parkway. It intersects CR 510 (South Orange Avenue) at the massive Cemetery of the Holy Sepulchre, then moves into Newark for about half a mile, then enters East Orange where  it meets CR 508 (Central Avenue). Shortly thereafter, it interchanges with Interstate 280, providing access to Newark, the Oranges and the Parkway. CR 509 continues north into Bloomfield, where it turns left onto Franklin Street. It crosses back under the Garden State Parkway before moving into Passaic County, through the cities of Clifton and Paterson, where it ends at CR 504. History. The two segments of CR 509 were previously connected through southern Union County via Raritan Road, Martine Avenue, West Broad Street, and Route 28. CR 509 Spur. County Route 509 Spur was a county highway in Union County . The highway extended from Broad Street (CR 509) in Westfield to Route 124 in Springfield. The road is now part of a southern extension of CR 577. Major intersections
