New York State Route 17 (NY 17) is a major state highway that extends for 397 miles (638.91 km) through the Southern Tier and Downstate regions of New York in the United States. It begins at the Pennsylvania state line in Mina and follows the Southern Tier Expressway east through Corning to Binghamton and the Quickway from Binghamton east to Woodbury, where it turns south to follow the Orange Turnpike to the New Jersey state line near Suffern, where it connects to New Jersey Route 17. From the Pennsylvania border to the village of Waverly and from Binghamton to Windsor, NY 17 is concurrent with Interstate 86 (I-86). Eventually, the entire east–west portion of NY 17 from the Pennsylvania border to Woodbury will become I-86 as projects to upgrade the route to Interstate Highway standards are completed.
The U.S. Route shield is the highway marker used for United States Numbered Highways. Since the first U.S. Route signs were installed in 1926, the general idea has remained the same, but many changes have been made in the details. Originally, the shield included the name of the state in which the sign was erected and the letters "U S" on a shield-shaped sign. Over time, the shield has been simplified to consist of a white shield outline on a black square background, containing only a black route number. However, because each state is responsible for the production and maintenance of U.S. Route shields, several variants of the shield have existed over the years.
A county highway is a road in the United States and in the Canadian province of Ontario that is designated and/or maintained by the county highway department. Route numbering can be determined by each county alone, by mutual agreement among counties, or by a statewide pattern.
A highway shield or route marker is a sign denoting the route number of a highway, usually in the form of a symbolic shape with the route number enclosed. As the focus of the sign, the route number is usually the sign's largest element, with other items on the sign rendered in smaller sizes or contrasting colors. Highway shields are used by travellers, commuters, and all levels of government for identifying, navigating, and organising routes within a given jurisdiction. Simplified highway shields often appear on maps.
In New York, a reference marker is a small green sign mounted approximately every one-tenth mile on highways maintained by the New York State Department of Transportation. This was initiated in response to the Highway Safety Act of 1966 enacted by Congress, in an effort to monitor traffic and identify high-accident locations. New York's system inventories and indexes all touring and reference routes, in addition to service and rest areas, ramps, and reservation roads.
County roads in Ohio comprise 29,088 center line miles (46,813 km), making up 24% of the state's public roadways as of April 2015. Ohio state law delegates the maintenance and designation of these county roads to the boards of commissioners and highway departments of its 88 counties. Each county has distinct construction, signage, and naming practices for the roads under its jurisdiction. Within each county, townships maintain separate township road networks under the advice of the county engineer. Each board of county commissioners certifies the total county- and township-maintained mileage within its county. The Ohio Department of Transportation catalogues these certifications on an annual basis.
The Ohio Manual of Uniform Traffic Control Devices is the standard for traffic signs, road surface markings, and traffic signals in the U.S. state of Ohio. It is developed by the Ohio Department of Transportation's Office of Roadway Engineering "in substantial conformance to" the national Manual on Uniform Traffic Control Devices developed by the Federal Highway Administration. The first edition of the OMUTCD was published in 1924; the most recent edition was published in 2012. Ohio is one of ten states that publish their own editions of the MUTCD.
