Interstate 10
Widening Project

ADOT plans to announce that the I-10 Widening project, southern Arizona’s largest transportation construction project to date, is nearing a milestone marking 50 percent completion. The $200 million project that began in January 2007 has completed building nearly half of the 4.5 miles of highway from Prince Road to 29th Street. The first improved section from Prince Road to Speedway Boulevard will be opened to allow interstate traffic to travel on the new pavement and structures north of St. Mary’s Road.
 
To facilitate this change, ADOT will be closing east and westbound I-10 temporarily from Friday, May 30 at 10 p.m. until Monday, June 2 at 5 a.m. During the closure, crews will be working to build the transition areas to the new pavement. Motorists will be detoured to the frontage roads during the temporary closure.
 
When I-10 reopens on June 2, drivers will be traveling on the west side of the freeway between Prince Road and 29th Street and should notice very little change in traffic control and signage. The final rubberized asphalt paving will not occur until the completion of the entire interstate project, but 60 percent of the roadway will have a new concrete surface. The interstate will remain two lanes in each direction and three lanes on the frontage roads for the remainder of the construction. Emergency pullouts have been added at each of the newly constructed closed entrance and exit ramps on eastbound I-10 from Prince Road to Speedway Boulevard and at each bridge on westbound I-10 from St. Mary’s Road to Miracle Mile.
