The Arizona Department of Transportation will be closing the Loop 101 on-ramps at the locations listed below on October 25th and 26th, 2021. The closures are planned to begin at 9:00 PM with the on-ramps re-opening no later than 5:00 AM.
The purpose of these closures is to perform upgrades to the ramp meters at the traffic interchanges. These upgrades will be a part of the ramp adaptive system. The upgraded system will be able to adjust the green time at the ramp meters based on the actual traffic conditions on the freeway.
During these times, traffic will be detoured around the closures. Portable dynamic message signs will be placed to inform motorists of the ramp closures. The work is scheduled at the locations shown below:
10/25/21 9 PM to 5 AM L-101 NB On Ramp at Union Hills
10/25/21 9 PM to 5 AM L-101 SB On Ramp at 75th Ave
10/26/21 9 PM to 5 AM L-101 WB On Ramp at 67th Ave
