Some major roads, particularly motorways and freeways, are given road numbers rather than, or in addition to, names. Examples include the E5, M1 and Interstate 5. Many roads in Britain are numbered as part of the Great Britain road numbering scheme, and the same applies in many other countries. The same is also common in the United States; for example, in Washington, D.C., much of New York Avenue is U.S. Route 50. In York Region, Ontario, the former provincial Highway 7 (currently signed as York Regional Road 7) is still referred to as "Highway 7" on road signs and in everyday use, even though the road has not been part of Ontario's provincial highway system since 1998. In the western United States, parts of the old U.S. Route 99 were taken over and added into the respective states' highway system and numbered "99" in the 3 states that the U.S. Route use to run through California, Oregon, and Washington. This is true for several other historic U.S. Routes, such as Route 66.
