Twin Tunnels

West of Exit I-40 354, Lupton, AZ

East < GO > West

To get to the twin tunnels under I-40 take the south frontage road about 5.3 miles from Lupton. That's a bit west of the I-40 Exit 354 interchange west of Lupton. Then take twin tunnels under I-40 to north frontage road (1931 Route 66 alignment) and go west to exit 351, the Allentown exit. The pre-1931 Route 66 is under I-40 from about where the tunnels are to Exit 351. As always with tunnels under I-40 watch out for flooding and soft mud in rainy weather.

x About Us We started traveling Historic U.S. Route 66 as a destination in 2009. It's like a 2,400 mile long drive back in time from Chicago to Santa Monica! more
xDid You Know: Many parts of the old 4 lane Route 66 were reverted to a 2 lane road after 66 was realigned to the interstate. In many places the abandoned lanes are still there.
