Detours required this weekend for roadwork on State Route 51, Loop 101 Agua Fria Freeway

PHOENIX – Two stretches of metro Phoenix freeway and associated ramps will be closed for improvement projects this weekend.

Roadwork on State Route 51 and the Loop 101 Agua Fria Freeway will have a significant impact on traffic, according to the Arizona Department of Transportation Weekend Freeway Travel Advisory for March 27-30.

In central Phoenix, southbound SR 51 will be closed from Glendale Avenue to Indian School Road from 9 p.m. Friday to 5 a.m. Monday for an ongoing pavement improvement project.

Two freeway closures for improvement projects are scheduled in the metro Phoenix area this weekend:
• SB SR 51 closed between Glendale Avenue and Indian School Road
• WB L-101 closed between Interstate 17 and 51st Avenue

The southbound SR 51 on-ramp at Northern Avenue, the entrance before the closure, will also be out of commission.

ADOT is advising motorists to take Interstate 17 as a detour to downtown Phoenix and Phoenix Sky Harbor International Airport or use southbound 16th Street, which is just east of SR 51, to bypass the closure area.

What is this weekend’s other metro Phoenix freeway closure?

Further north, westbound Loop 101 will be closed from I-17 to 51st Avenue from 10 p.m. Friday to 5 a.m. Monday for a long-term widening project.

The ramps from both directions of I-17 to westbound Loop 101 will be closed, too, as will the westbound Loop 101 on-ramps at Seventh Street and Seventh Avenue.

In a related restriction, northbound I-17 will be limited to two lanes from Loop 101 to Pinnacle Peak Road from 9 p.m. Friday to 5 p.m. Sunday.

Drivers should consider alternative routes such as Bell Road or Union Hills Drive while westbound Loop 101 is closed, ADOT said.
