PHOENIX — A two-monthlong closure of the westbound Loop 101 Agua Fria Freeway on-ramp at 27th Avenue will start Monday night.

The on-ramp closure that will start at 11:30 p.m. is due to a multimillion-dollar reconstruction project, according to the Arizona Department of Transportation.

Drivers who rely on the westbound on-ramp should enter the freeway at 35th Avenue, ADOT said.

When will the westbound on-ramp at 27th Avenue on Loop 101 reopen?

That project is part of a broader freeway widening project west of Interstate 17.
