The U.S. Roads Portal

The highway system of the United States consists of US routes and interstates. In addition, all fifty states, the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands all maintain their own systems. Despite their names, US routes and interstates are the responsibility of the state department of transportation where they are located.

The US Routes (also known as U.S. Highways) are even numbered for east-west routes (with the lowest numbers along Canada) and are 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 two-digit "parents" (for example, U.S. Route 271 is a branch of U.S. Route 71).

Interstates are also even numbered for east-west routes (but the lowest numbers are along Mexico and the Gulf of Mexico), and the 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 270 is a beltway around the city of St. Louis, Missouri and is connected to Interstate 70).

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 somehow connected to their state. Many use an outline of the state with the number inside.

Approximately 3000 articles have been written on interstate, US, and state roads.

New York State Route 104 is a 182-mile (292.8 km) long east-west highway in Upstate New York, USA. The entire length of the road was designated U.S. Route 104 until 1972, except for locations near Rochester where the highway has since been moved onto expressways. NY 104 travels from New York State Route 384 near the Rainbow Bridge in Niagara Falls in Niagara County to New York State Route 13 near Altmar in Oswego County. Route 104 primarily runs parallel to the south shore of Lake Ontario throughout most of its route between the Niagara River in Niagara Falls and the Oswego River in Oswego.

Before US 104 was created, the roadway carried a number of designations, namely New York State Route 3, New York State Route 18 and New York State Route 31. All three of these routes were reconfigured to allow for the designation of US 104.

Over time, the 104 designation has been shifted from surface streets to expressways and Super-2s, particularly from Rochester east to Oswego. The first such realignment occurred in the late 1940s in western Wayne County and was completed by the realignment of NY 104 onto the Irondequoit-Wayne County Expressway near Webster in the early 1980s.
