List of county routes in Sullivan County, New York
# List of county routes in Sullivan County, New York

County routes in Sullivan County, New York, are maintained by the Sullivan County Division of Public Works and signed with the Manual on Uniform Traffic Control Devices-standard yellow-on-blue pentagon route marker. The county highway system comprises roughly 140 routes arranged across the county in groups of nine. For the most part, state routes in Sullivan County are county-maintained and co-signed with county routes. However, the converse is not true; that is, not all county routes overlap state routes for their entire length. Typically, each series consists of county routes along a single roadway, often overlapping with state highways in the process. The lowest numbered route in the system is County Route 11 (CR 11); the highest is CR 183C. Note that routes 160 through 169 do not conform to any style, and coincidentally the 170 through 179 series (with the exception of the spur designated 174A) follows the pre-expressway routing of New York State Route 17 (NY 17).

Sullivan County posted signage of their routes in 1958.

## Routes 1–50

### Barryville to Claryville (11–19)

The Barryville to Claryville series encompasses routes 11 through 17 and CR 19, the non-suffixed of which form a mostly continuous roadway between the two communities. Most of the routes are concurrent to NY 55, which follows the Barryville–Claryville route from Barryville north to Curry. At Curry, CR 19 splits from NY 55 to access Claryville. The Barryville–Claryville route is interrupted four times by three state-maintained stretches of NY 55 (from CR 13 to CR 14; from CR 16 to CR 17; and from CR 17 to CR 19) and a locally maintained section within the village of Liberty.

### Mongaup to Yulan (31–33)

The Mongaup to Yulan series is only CR 31 through CR 33, as routes 34 through 39 do not currently exist within the county. The roadway begins as CR 31 at NY 97 in Mongaup and heads northwest to a junction with CR 21 and CR 22 in Yulan. CR 31 and CR 32 do not directly intersect each other; instead, they are connected by the northernmost portion of CR 41.

CR 47 is a spur off CR 32 from Eldred to Highland Lake. The route itself does not connect to any other route in the Pond Eddy-Monticello series; however, the unnumbered Mohican Lake Road continues east from the eastern terminus of CR 47 to intersect CR 42 near Glen Spey. The remaining routes are spurs off the main Pond Eddy–Monticello route.

CR 131 and CR 132 run from CR 121 north of Hortonville to NY 97 at Hankins. CR 134 begins at a junction with NY 97 about 3 miles (4.8 km) to the north and heads northeast through Basket to the Delaware County line. CR 133 and its spur do not connect to any of the other routes in the series; instead, they serve to connect NY 97 in Callicoon to the Callicoon Bridge over the Delaware River.

### Routes 151–158

Unlike most numerical groupings in Sullivan County, the county routes numbered 151 through 158 do not form a continuous roadway, save for CR 151 and CR 152. However, the routes are all spurs connecting the rest of the route system to the Ulster County line.

Like the 150 series, the county routes numbered from 161 to 168 (161–164, 166, 166A, and 168 in actuality) do not form a series. However, in this case, most of them are not related.

### Roscoe to Bloomingburg (171–179)

The Roscoe to Bloomingburg series is made up of county routes 171 through 176, 178, and 179, plus three spur routes. All eight mainline routes are mostly continuous and collectively extend from the Delaware County line northwest of Roscoe to the Bloomingburg village line just west of the Orange County line. In between, the route serves Liberty, Monticello, and Wurtsboro via locally maintained highways as the county designations end at the village limits. The series parallels the NY 17 expressway for its entire length and also runs along the southern boundary of Catskill Park from Livingston Manor to the Delaware County line.

Most of the eight mainline routes and CR 179A were originally designated as part of NY 17 in 1924. In the vicinity of Wurtsboro, however, NY 17 initially followed modern CR 166. It was realigned between 1935 and 1938 to use what is now CR 172 instead. Construction began in the early 1950s on a new limited-access alignment for NY 17 through Sullivan County. Over the next 10 years, NY 17 was realigned to follow the freeway as new sections of it opened up. By 1962, all of the modern Quickway from Parksville to Bloomingburg was complete and open to traffic. The highway was extended north to Livingston Manor (exit 96) by 1964 and completed through Sullivan County by 1968.
