Interstate 10 between Tucson and Benson has reopened.
It was closed overnight so crews could demolish the Pantano Union Pacific Railroad Bridge.
Motorists were faced a detour of 67 miles along highways 90, 83 and 82 through Sonoita.
The closure began at 9 p.m. Friday. Eastbound lanes were reopened first, shortly before 7 a.m. Westbound lanes were opened just a few minutes later.
