Construction crews will close down eastbound Interstate 10 east of Tucson Tuesday night, forcing drivers to take a 67-mile detour.
Crews will replace a bridge on I-10 between Tucson and Benson. The closure will go from 9 p.m. Tuesday until 5 a.m. Wednesday.
Westbound I-10 drivers headed toward Tucson should expect the trip to take as much as two hours longer. Eastbound drivers won't be affected.
