Interstate 280

Interstate 280 loops southeast from I-80 at Parsippany-Troy Hills township through the Oranges and Newark to the New Jersey Turnpike at Kearny. The 17.85 mile long freeway varies from suburban areas in Essex County to a pronounced drop from Watchung First Mountain in West Orange township to an urban below grade freeway through East Orange.

The first portion of I-280 completed was the pre-Interstate route of Route 25A, a 1.1 mile route between Clifton Avenue in Downtown Newark and Grant Avenue in Harrison. This included the 1949-opened Passiac River lift bridge (William J. Stickel Memorial Bridge). Work followed in 1960 in the Oranges, with 14.5 miles of I-280 completed by 1973 from Parsippany to Harrison. The final 3.4 miles from Harrison to I-95 at Kearny, opened in 1980 (Anderson, n.d.).
