Completed Loop 101 widening means reduced use of ramp meters

Changes based on improved traffic flow along Scottsdale-area segment

PHOENIX – One of the benefits of the recent widening of Loop 101 in the Scottsdale area is that on-ramp meters, featuring those alternating green and red traffic signals, won’t be in use as often now.

Ramp Meter on Loop 101 with traffic flowing behindThe Arizona Department of Transportation followed up on the addition of new Loop 101 lanes by assessing improved traffic conditions between Frank Lloyd Wright Boulevard and Loop 202 (Red Mountain Freeway). The result: Most ramp meters in that area will now be used about half as often as they were before ADOT launched the $73 million project to improve 11 miles of Loop 101 south of Shea Boulevard.

The ramp meters in the Scottsdale area weren’t in use during construction, which included rebuilding on- and off-ramps along the freeway. Crews are scheduled to activate the meters again starting Monday, Dec. 12. Prior to the widening project, the meters were used during both the morning and afternoon peak commute times.

With reduced congestion, drivers can expect most Loop 101 ramp meters in the Scottsdale area to be used during only one peak commute period each weekday. 

For example, ramp meters along the busier northbound Loop 101 between McKellips and Indian Bend roads will only be in use from 7 a.m. to 9 a.m. weekdays. Conversely, most ramp meters along southbound Loop 101 between Frank Lloyd Wright Boulevard and McKellips Road will only be used during the 3 p.m. to 7 p.m. peak commute times. The hours of operation will vary slightly depending on location and anticipated traffic conditions (see the list below).

The northbound Loop 101 ramp meters at Via De Ventura, 90th Street and Shea Boulevard will still be used during both the morning and afternoon rush hours. At this time, the southbound Loop 101 ramp meter at Shea Boulevard and northbound meter at Cactus Road won’t be used at all. The southbound ramp meter at Raintree Drive will be limited to use during the morning rush hour.

Ramp meters are used to enhance traffic flow by providing space between vehicles entering freeways across the Phoenix area. That space between vehicles also promotes safer merging conditions for drivers who are either entering or exiting freeways.

Ramp meter use and hours of operation are subject to change depending on future traffic conditions.
