Central Avenue in Jersey City Heights is the main commercial thoroughfare for that section of Jersey City, New Jersey, USA, and is designated County Route 663 for of its length. It runs just north of Newark Avenue near Five Corners to Paterson Plank Road near Transfer Station. The avenue continues north through Union City without the county route designation to 35th Street, two blocks north of Hackensack Plank Road. Central Avenue was the "Main Street" of Hudson City, one of the municipalities which elected to join Jersey City in a referendum held in 1863. The avenue begins at what had been the southern border of the town that is now near the county seat of Hudson County and the historic Hudson County Courthouse. Traveling north it almost immediately passes over three man-made ravines, or "cuts" through the part of the Hudson Palisades called Bergen Hill. The now-unused Bergen Arches and the single trackLong Dock Tunnel were created for railroads, while The Depressed Highway was created to allow traffic to by-pass local roads while travelling between the Holland Tunnel and the Pulaski Skyway. In July 2012, the Hudson County Board of Chosen Freeholders passed a resolution to extend the avenue between Hoboken Avenue and Newark Avenue The work would be done in conjunction with the replacement of the Hudson County Administration Building with a new courthouse. Land for the new building had been acquired by the end of 2017. In September 2018, allocations for design of the site were made construction planned for 2020. On entering the Heights, it becomes residential for a few blocks, as it passes the Jersey City Reservoir #3 and Pershing Field. Thereafter it becomes a local shopping street. Businesses, retail and food shops are mostly located in three and four story buildings, many built in the late 19th and early 20th century. It again becomes more residential as it approaches the city line in Washington Park. The trajectory of the avenue is adjusted by a short "dog-leg turn" to the west along Paterson Plank Road and resumes in what was formerly West Hoboken and is now a section of Union City. It is a broad residential street of multiple family houses and low and mid-rise apartment buildings. At 18th Street, the avenue is once again "interrupted", this time at the grounds of the former Monastery and Church of Saint Michael the Archangel. It continues on the other side and soon thereafter passes over the Lincoln Tunnel Approach and Helix. Central Avenue ends two blocks north of the 32nd Street section of the Hackensack Plank Road near the Holy Family Church complex, which includes the Park Theater, just west of Bergenline Avenue.
