Weekend freeway travel restrictions for Valley

PHOENIX -- Multiple freeways will be affected over the weekend due to construction and cleaning.

Regularly scheduled tunnel cleaning will require closing eastbound Interstate 10 overnight Friday and westbound I- 10 Saturday night near downtown Phoenix. Crews installing new, easier-to-read overhead signs will take advantage of the nighttime closures to complete their work in the same location.

Southbound State Route 143 also will be closed this weekend while workers paint one of the newly built ramp structures.

The Arizona Department of Transportation makes the following closures notable and advises driver to seek alternate routes if possible.

• Eastbound I-10 closed between I-17 and Seventh Street near downtown Phoenix from 9 p.m. Friday to 7 a.m. Saturday for tunnel cleaning and overhead sign installation.

DETOUR: All traffic will detour onto north or southbound I-17. Drivers on eastbound I-10 can use southbound I-17 to reconnect with I-10 at 24th Street near Phoenix Sky Harbor International Airport.

• Westbound I-10 closed between Seventh Street and Seventh Avenue near downtown Phoenix from 9 p.m. Saturday to 7 a.m. Sunday for tunnel cleaning and overhead sign installation.
