Route 208 is a state highway in the northern part of New Jersey in the United States. It runs from an interchange with Route 4 and County Route 79 (CR 79, Saddle River Road) in Fair Lawn northwest to an interchange with Interstate 287 (I-287) in Oakland borough line. The route runs through suburban areas of Bergen and Passaic counties as a four- to six-lane divided highway. The route runs through the communities of Fair Lawn, Glen Rock, Hawthorne, Wyckoff, and Franklin Lakes along the way, interchanging with CR 507 in Fair Lawn and CR 502 in Franklin Lakes.
What is now Route 208 was initially planned as Route S4B in 1929, a spur of Route 4 that was to run from Fair Lawn northwest to the New York border in Greenwood Lake, where it would eventually connect to New York State Route 208 (NY 208). This route replaced what was planned as a part of Route 3 in 1927 between Paterson and Greenwood Lake. By the time the route was renumbered to Route 208 in 1953 to match NY 208, only a portion of the route in Fair Lawn from Route 4 to Maple Avenue had been built. Route 208 was completed west to U.S. Route 202 (US 202) in Oakland by 1960 as a two-lane undivided road; it would be built into its present configuration in later years. A Route 208 freeway was planned across the Ramapo Mountains from Oakland to connect to a proposed NY 208 freeway at Greenwood Lake; however, it was never built. After I-287 was extended from Montville to the New York border in 1993, it took over the alignment of Route 208 between US 202 and the route’s current northern terminus. The last traffic signal along Route 208 at McBride Avenue was removed in 1995 and the interchange with Route 4 and Saddle River Road was reconstructed in 2002.
Route description
Traffic moves in at least two lanes in each direction for the road's entire length of , widening briefly to three lanes next to a commercial area in Fair Lawn and near its northern terminus. Shortly after beginning, a ramp from southbound Route 208 provides access via Virginia Drive to westbound Route 4. This route was to replace what was to be a portion of Route 3 between Paterson and the New York border that was designated in the 1927 New Jersey state highway renumbering. The road was projected to continue into New York and continue through Sterling Forest and Monroe, New York, where it would join NY 208 at its intersection with NY 17. By 1953, the portion of Route S4B between Route 4 and Maple Avenue in Fair Lawn was completed; that same year, it was renumbered to Route 208 in order to match NY 208. By 1960, the road was extended to a northern terminus at US 202 and West Oakland Avenue in Oakland, where traffic could exit and continue over Skyline Drive to Ringwood. When first constructed, this portion of Route 208 was a two-lane undivided road. By 1969, the portion between Maple Avenue and Goffle Road was widened to a divided highway with the entire route built into a multi-lane divided highway by the 1980s.

Meanwhile, plans still existed to build Route 208 past Oakland to the New York border. Passaic County called for a divided highway to bypass Skyline Drive, and in 1967 the New Jersey Department of Transportation (NJDOT) proposed a Route 208 freeway through the Ramapo Mountains that would run from Oakland to the New York border in Greenwood Lake, where it would connect to a proposed NY 208 freeway (called the Orange Expressway) that would continue north to I-84 in Maybrook, New York. This freeway, which was to cost $66.3 million, was to improve traffic in the resort areas of the Ramapo Mountains and also connect to the proposed Route 94 freeway leading to Warren County and the proposed Route 178 freeway leading to Morris County. In 1975, this proposed freeway was recommended by the Tri-State Regional Planning Commission to be completed by 2000. However, it was never built.

When I-287 was extended from Montville to the New York border in 1993, it took over the alignment of Route 208 between US 202 and the current northern terminus of Route 208. In 1995, the last traffic signal along Route 208 at McBride Avenue was turned off. In 2002, construction was completed on a $32 million project that improved the interchange with Route 4 in Fair Lawn. This interchange saw improvements of the ramps and bridges, including the Route 208 bridge over Saddle River Road. Route 208, like many other highways in New Jersey, once had solar powered emergency call boxes every ; however with the advent of cell phones the usage of these call boxes became extremely limited. To save on maintenance costs, the NJDOT removed these call boxes in 2005.
