# List of highways in Essex County, New York

The highway system of Essex County, New York, comprises 1,367.8 miles (2,201.3 km) of roads maintained by the New York State Department of Transportation, the county, and its towns and villages. Eighteen state-maintained highways enter the county, which account for a combined 329.4 miles (530.1 km) of the state highway mileage in New York. The state roads are supplemented by 356.7 miles (574.1 km) of county-maintained highways, most of which serve as collector roads between state highways. Several highways within the borders of the county serve as connections to ferry landings and bridges across Lake Champlain.
Essex County is served by one Interstate Highway, I-87, known locally as the Adirondack Northway. US 9, the only United States Numbered Highway in the county, closely parallels I-87 as both highways head north–south across the county. Essex County is also served by 11 state touring routes and six reference routes, the latter of which are short unsigned connectors. The longest touring route in Essex County is NY 9N, which runs for 67.69 miles (108.94 km) through the county. The county's shortest touring route is NY 373, which runs for 3.20 miles (5.15 km) in the northeastern part of Essex County.

## Highways
### Interstate and US Highways

There is one interstate highway in Essex County, I-87, stretching for 57.23 miles (92.10 km) from the Warren County line near Schroon Lake to the Clinton County line north of Keeseville. The highway was assigned after being built in 1967 to connect Keeseville to the Clinton County line, paralleling the alignment of US 9.
There is one U.S. Route in Essex County, US 9, which runs for 58.99 miles (94.94 km) in two segments. The first, spanning 57.83 miles (93.07 km), enters from Warren County near Schroon Lake before entering Clinton County temporarily. The second, spanning 1.16 miles (1.87 km), stretches from both lines of Clinton County. US 9 was assigned in the area in 1926 along a stagecoach route and has remained virtually unchanged since.

### State touring routes

There are 10 state touring routes in Essex county, the longest of which is NY 9N at 67.69 miles (108.94 km), which stretches from the Warren County line near Lake George to the Clinton County line north of Willsboro. The shortest is NY 373, running for 3.20 miles (5.15 km). Some state highways which once entered Essex County have been eliminated, including NY 192 (now part of NY 86), NY 427 and NY 86A (both now part of NY 73); others, like NY 8, still exist but no longer pass through the county. NY 8 was once concurrent with Routes 9N and 22, which continue into Essex County from Warren County, and the route ended in Crown Point at the Vermont border. The northernmost segment of NY 8's former routing through the county is now NY 185.

### State reference routes

There are six reference routes in Essex County; a seventh, NY 910L, was redesignated NY 185 on April 4, 2008, as part of a New York State Department of Transportation project to rehabilitate the Champlain Bridge. Around this time, there was an addition to the highway system, with the designation of NY 915K, a short connector leading to exit 33 on the Adirondack Northway. The longest reference route is NY 910M at 0.81 miles (1.30 km), running from John Brown's Grave to NY 73. The other three reference routes are NY 910K (part of the Blue Ridge Road), NY 912T (the shortest reference route, at 0.12 miles (0.19 km), and a connector to NY 373), and NY 913Q, which serves Mount Van Hoevenberg in North Elba.

### County routes

There are over 60 county routes in Essex County, signed with the pentagonal county highway shields found in most of the state. The first in order is CR 2, also known as Corduroy Road and Creek Road in Ticonderoga; the last is CR 86E, known locally as Saint Huberts Road in Saint Huberts. In Keene, there are five county routes along NY 73 that are former alignments of NY 86A, which previously ran along that alignment.
