TUCSON - Southern Arizona drivers are urged to plan ahead to prepare for a 67-mile detour.
Beginning at 9p.m. Friday, Interstate 10 east of downtown Tucson will be closed in both directions until 6 a.m. Saturday.
That's between State Route 83 east of Tucson (Exit 281) and SR 90 west of Benson (Exit 302).
There will be signs to help guide drivers through the long detour.
Drivers can expect up to two hours of additional travel time.
Crews are shutting down the interstate so they can remove the old Pantano Union Pacific Railroad Bridge.
The bridge is no longer needed because the railroad company has moved its tracks and the bridge is no longer in use.
It was also too low for commercial trucks, requiring many of them to take detours.
Demolishing it will make travel more efficient for commercial trucks.
In order to prepare for the bridge removal, there will be lane closures beginning at 7a.m. on eastbound and westbound I-10 in the area of the Union Pacific Railroad Bridge.
The speed limit will be reduced and one lane will remain open in each direction.

Drivers can also get road conditions from the Arizona Department of Transportation by calling 511.
