Construction on New I-10 bridges over the Gila River Begins

Press Release

Arizona Department of Transportation

 

The Arizona Department of Transportation (ADOT) has begun construction of the new I-10 bridges over the Gila River and is part of the I-10 Wild Horse Pass Corridor Project that runs along 26 miles of I-10 in both directions between the Loop 202 (Santan/South Mountain Freeway) and State Route 387 near Casa Grande.

 

Construction of these new bridges is one segment of the project’s four segments. The other segments of the project are expected to begin at later dates throughout the next few years. Work for the entire I-10 Wild Horse Pass Corridor Project is expected to take place between early 2024 through late 2028.

 

Crews will construct the new bridges next to the existing ones and any planned roadway restrictions during construction will take place overnight in order to minimize the impact on motorists.

 

Major construction components of the new I-10 bridges over the Gila River include:

  • Adding an additional lane in both directions (replacing the two lanes in each direction on the bridges to three lanes in each direction)
  • Reconfiguring the approach to the bridges on both ends
  • Widening the shoulders of the bridges

 

Once completed, the I-10 Wild Horse Pass Corridor Project will have widened I-10 by adding an additional lane between south of Chandler to north of Casa Grande, providing motorists with three continuous lanes of travel in each direction between Phoenix and Tucson. Other major components of the I-10 Wild Horse Project include:

  • Extending the High Occupancy Vehicle (HOV) lanes in each direction on I-10 from Loop 202 (Santan/South Mountain Freeway) to Riggs Road
  • Improving interchanges and crossroads for enhanced capacity and safety, and multimodal (bike and pedestrian) crossings
  • Installing a fiber optic backbone to install freeway management technology to allow for installation of sensors, cameras, variable message signs and other highway operations and safety-related technology.

Funding for the I-10 Wild Horse Pass Project comes from both the state and federal governments, including a $95 million federal grant. Some funding of the project is through Prop 400, a half-cent sales tax that was approved by Maricopa County voters in 2004.
