Designating the Urban Interstates

A Street in U.S. Route 1 Virginia

Free flow of traffic and turning movements on urban portions of the interstate system are often hampered by traffic lights, narrow streets, parking, and entrances to gasoline stations and other business establishments, as shown here on U.S. route 1 in Virginia. Improvement to interstate system standards would save 21 billion vehicle-minutes--almost 40,000 years-- annually
