The Arizona Department of Transportation will close the westbound right lane of Interstate 10 between mileposts 292-293 on September 30, 2026. This closure is scheduled to occur from 5 a.m. to 3 p.m. to facilitate the I-10 Amole Traffic Interchange and UPRR Bridge Rehabilitation Project.
Why it matters
The lane closure and associated construction work are necessary to support critical bridge and interchange rehabilitation efforts in the Tucson area. These modifications aim to improve infrastructure longevity and traffic safety within the corridor.
The project corridor maintains a 16-foot vehicle width restriction and a reduced speed limit of 55 mph. These restrictions are in effect for the duration of the bridge rehabilitation efforts between mileposts 292-293.
The players

This state agency is responsible for the planning, construction, and maintenance of Arizona's state highway system and public transit infrastructure.
The details
Drivers should expect significant traffic shifts due to the lane closure and ongoing flagging operations on Marsh Station Road, which occur weekdays from 5 a.m. to 3 p.m. The measures are essential for the safe execution of the I-10 Amole Traffic Interchange and UPRR Bridge Rehabilitation Project.
Timeline
September 30, 2026: Westbound I-10 lane closure at mileposts 292-293.
Monday through Friday: Daily flagging operations on Marsh Station Road.
Market Landscape
The I-10 Amole Traffic Interchange and UPRR Bridge Rehabilitation Project represents a critical phase in modernizing regional infrastructure to accommodate increased traffic density. Such projects reflect a broader industry trend of prioritizing aging bridge and interchange safety over immediate highway throughput.
Commuters traveling through the project area should anticipate delays and adhere to the reduced 55 mph speed limit to ensure safe transit. Oversized vehicles exceeding the 16-foot width restriction will need to plan alternate routes to avoid the construction zone.
The takeaway
Travelers should allow for extra time during their morning and afternoon commutes while the bridge rehabilitation work is ongoing. Checking local traffic updates before departing can help residents navigate around the restricted lane and flagging zones.
