A new proposal would designate Route 66, the mother road, that connected Chicago to Los Angeles, as a national historic trail. U.S. Senators Tom Udall and Jim Inhofe recently introduced a bill that would amend the national trails system act in an effort to help revitalize cities and small towns that sit along the historic Route 66 corridor. The use of Route 66 dropped significantly after highways were built as part of the interstate system. It was decommissioned as a U.S. Highway in 1985.
