In 1960, construction of I-280 began in the Orange-West Orange area.Between 19, 14.5 miles of the route from Parsippany east to Harrison were opened to traffic, leaving 3.4 miles of I-280 remaining unbuilt.In 1954, one year after the highway was re-christened NJ 58, an approach stretching one-half to the west of the lift span was opened to traffic.
The freeway will extend from parent I-80 in Parsippany-Troy Hills Township, Morris County to I-95 (New Jersey Turnpike) in Kearny.
The original plans for I-280 called for an elevated roadway through Newark and East Orange.
To hold down construction costs, the state commissioned the engineering firm S. Groves and Sons to construct a temporary railroad along the I-280 right-of-way.
Engineers first cut through First Mountain, and had approximately 1.5 million cubic yards of rock ready to haul to a replacement fill toward the western end of I-280, where a separate section was being graded over unstable land.
Despite the new Interstate designation - and the promise of Federal funding - construction of I-280 was delayed for years.
