County routes in New Jersey

County Route 577, abbreviated CR 577, is a county highway in the U.S. state of New Jersey. The highway extends 9.96 miles (16.03 km) from Springfield Avenue (Route 124) in Springfield Township to Bloomfield Avenue (CR 506) in Verona.

CR 577 begins at an intersection with Route 124 in Springfield Township near the western terminus of Route 82. The highway originally started further south, at the intersection of Broad Street and Springfield Avenue in Westfield; Broad Street and eastbound Springfield Avenue are CR 509, while CR 577 went west and north on Springfield Avenue, which becomes Meisel Avenue as it enters Springfield. This route was changed in the past from CR 577 to CR 509 Spur (although the old signage was often left intact) but may have been changed back. In downtown Springfield, where most of the major streets are one-way, Maple Avenue carries the nominal route northbound to the official southern terminus, while Meisel Avenue carries the southbound traffic.

From the official southern terminus, the route heads north as two-lane undivided Main Street, which is municipally maintained. The road runs through suburban residential development, passing over I-78 and crossing into Millburn in Essex County. In Millburn, CR 577 reaches a junction with CR 527, at which point the route turns east onto a one-way pair that is county maintained. Northbound CR 577 follows three-lane Millburn Avenue and southbound CR 577 follows two-lane Essex Avenue on this pairing, which passes through the commercial downtown of Millburn. At the end of the one-way pair, the route becomes four-lane undivided Millburn Avenue and continues east through a mix of homes and businesses. At the Wyoming Avenue intersection, CR 577 turns northeast onto that road while CR 630 continues along Millburn Avenue.
