New Jersey Route 15 - Route Description

Route Description

Route 15 begins at an interchange with U.S. Route 46, slightly to the east of the underpass Route 15 used to use to pass under U.S. Route 46 and access Dover. Route 15 then winds through Dover concurrent with several streets. The road remains two lanes past the turn for the Rockaway Townsquare Mall, in the township of Rockaway. For a very short distance Route 15 becomes a freeway as it crosses the Interstate 80 interchange. A mile north, the road becomes a four lane divided highway with exits for a few businesses and Picatinny Arsenal. At that point, Route 15 leaves Rockaway Township and enters Jefferson Township. In Jefferson Township, the northbound and southbound lanes become about a quarter mile apart as it climbs up a steep mountain. The Southbound lanes have businesses, easy access to them, and a speed limit of 40 mph as this was the original lanes of Route 15 when it was only a 2 lane highway. The northbound lanes are nearly a freeway with limited access to businesses on the southbound lanes. The northbpund lanes have a spees limit of 50 mph as well. These two lanes were built in the late 1960s.

Slightly farther north, Route 15 becomes a freeway and the northbound and southbound lanes come closer together. At this point, the original two-lane Route 15 breaks off into Route 181, heading through Jefferson Township and into downtown Sparta. Several miles north, the freeway leaves Morris County in Jefferson Township and enters Sussex County and Sparta Township, bypassing downtown Sparta. After bypassing downtown Sparta, Route 181 ends and merges onto Route 15. The freeway then ends and Route 15 becomes a two-lane road. After Route 15 leaves Sparta and enters Lafayette Township, it merges with Route 94. Routes 15 and 94 run as a concurrency until Route 94 turns off to the southeast while Route 15 heads northwest. It continues into Frankford Township and comes to an end at U.S. Route 206 and County Route 565.
