It's difficult to imagine an America that is not criss-crossed by highways. But it hasn't always been this way. Return to a past in which the interstate system was a new and futuristic feature of the landscape at 6 p.m. tonight at the Missouri History Museum (Lindell Boulevard and DeBaliviere Avenue; www.mohistory.org). The Route 66 Vintage Films screening features a selection of educational and promotional films about driver safety, new developments in traffic lights and the latest in automotive technology between 1930 and 1970. The program is a tie-in to the museum's Route 66 exhibition, which closes on Sunday, July 16. Admission is free.
Price: free admission
