The steep and narrow road is often impassable in winter due to ice and snow and is as high as 900 ft above sea-level in some places along the route.

This ban follows an incident in December 2000, in which three Ringwood residents were killed by a 40-ton dump truck that had lost control on the roadway and fell to its side.

The route heads westward as West Oakland Avenue, crossing over the New York, Susquehanna and Western Railway's New Jersey Subdivision line and paralleling to the south of Interstate 287.

At this point, Route S-91 continues northward along Skyline Drive, crossing under the mainline of Interstate 287 and entering the nearby partial cloverleaf interchange.

After crossing through a large residential complex, the highway continues curving its way northward, turning westward one final time at the intersection with Erskine Road.

[5][6] This replaced earlier plans that had called for State Highway 3 to service the area, albeit through a more southerly corridor directly through Pompton Lakes.

[11] After being extended to West Oakland Avenue, Route 208 ended near Skyline Drive, where drivers could continue northward to Ringwood and Erskine.
