Road work this weekend will affect access to Sky Harbor Airport and close several ramps and sections of Route 143 between Loop 202 and Intestate 10.

The Arizona Department of Transportation advises drivers to plan ahead and plan to use detours as southbound SR 143 will be closed between Loop 202 and I-10 from 10 p.m. Friday, March 22, to 4 a.m. Monday, March 25, for paving. These ramps will also be closed:

• The ramps from Loop 202 to southbound SR 143.
• The westbound Loop 202 off-ramp at Sky Harbor Boulevard.
• The southbound SR 143 on-ramps at Washington Street, Sky Harbor Boulevard and University Drive.

The southbound SR 143 detour for westbound Loop 202 drivers is westbound Loop 202 to eastbound I-10 to access destinations south of the closure. Eastbound I-10 drivers using the off ramp at 48th Street will only be able to turn right on 48th Street, transportation officials said.

Eastbound Loop 202 drivers should take eastbound Loop 202 to southbound Loop 101 to westbound US 60 to reach destinations south of the closure, according to ADOT.

East Valley airport access: From Loop 202, use southbound 44th Street.
