Interstate 8 and Araby Road (State Route 195) Traffic Interchange Improvements

Project Background

The Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHWA) have identified the need to improve the Interstate 8 / Araby Road (SR 195) traffic interchange to improve safety and ease traffic congestion.

An $8.1 million project funded by the FHWA Highway Safety Improvement Program began in July 2017 and is occurring in two phases. Crews are constructing two, two-lane modern roundabouts and associated ramps to I-8 and Gila Ridge Road. This project also includes construction of storm drains, a retention basin, concrete barriers and retaining walls and installing lighting and landscaping.

One roundabout will be located north of I-8 and serve Araby Road and the westbound ramps. The other roundabout will be south of I-8 and serve Araby Road, the eastbound ramps and Gila Ridge Road.

The intersection of I-8 and Araby road is among the busiest in Yuma and is used by approximately 22,000 vehicles per day. The new roundabouts will provide a high level of service beyond traffic projections for 2035 and will fit into the existing ADOT right-of-way. No new right-of-way is needed to accommodate this project.

Two Phases of Construction

To minimize the impact on Yuma's winter visitors and the peak produce season, ADOT has scheduled work to occur in two phases:

  • Phase 1 occurred from July to November 2017 on the north side of the interchange. The first roundabout opened on Oct. 27, 2017.
  • Phase 2 of construction is scheduled to occur on the south side of the interchange from May 2018 through fall 2018.
Impacts to Traffic

Drivers should plan to use detour routes and allow plenty of extra travel time while long-term lane closures and restrictions are in place at I-8 and Araby and Gila Ridge roads. Alternate routes include Avenue 3E and 32nd Street.

Roundabouts: A Feasible Solution

A comprehensive traffic study determined that modern roundabouts are the best choice to meet traffic needs well into the future. Modern roundabouts often provide a better solution than signalized intersections because they are safer and more efficient.

The new roundabouts at I-8 and Araby Road are designed to accommodate large commercial trucks, agricultural equipment and recreational vehicles. Several area trucking and agricultural stakeholders provided input on the design to ensure even the largest trucks can navigate through the roundabouts.
