The highway system of the United States is a network of interconnected state, U.S., and Interstate highways. Each of the fifty states, the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands own and maintain a part of this vast system, including U.S. and Interstate highways, which are not owned or maintained at the federal level.

Interstate Highways have the highest speed limits and the highest traffic. Interstates are numbered in a grid: even-numbered routes for east–west routes (with the lowest numbers along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). Three-digit interstates are, generally, either beltways or spurs of their parent interstates (for example, Interstate 510 is a spur into the city of New Orleans, Louisiana, and is connected to Interstate 10).

U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.

State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.

State Route 339 (SR 339) is a 8.5-nautical-mile-long (9.8 mi; 15.7 km)[1] ferry route designated as a state highway in the U.S. state of Washington. It connects Vashon Island's Vashon Heights ferry terminal to downtown Seattle's Pier 50, via a passenger-only ferry, the MV Skagit. The ferry is financed by the King County Ferry District (KCFD) and tolls collected at Pier 50. Despite being part of the KCFD, the ferry is operated by Washington State Ferries (WSF).[2] SR 339 is one of only four ferry routes providing access to and from Vashon Island, and has the lowest annual average ridership of the four routes. The state of Washington took over the operation of the ferry route in 1951, and designated it SR 339 in 1994.
