TUCSON, AZ (Tucson News Now) - For the next 18 months, drivers who frequent Interstate 10 between Tucson and Phoenix, will be seeing more construction work as crews begin widening the interstate to three lanes in each direction.
According to an Arizona Department of Transportation news release, widening work will take place from just south of Earley Road to Interstate 8 (mileposts 196 - 200) in Casa Grande. The project is expected to cost $36.6 million and be completed by summer 2019.
It will add one lane of travel in each direction adjacent to the median, with a concrete barrier separating travel, as well as create new bridges over Jimmie Kerr Boulevard. Auxiliary lanes in both directions between I-8 and Jimmie Kerr Boulevard will also be added during the project, providing a safer alternative to the existing ramps.
Though construction crews will be working near the travel lanes, increased congestion is not expected in the area near Casa Grande.
Night time lane restrictions are expected to take place during construction, according to ADOT. Leaving two lanes open to travel in both directions during heavy travel times.
A joint venture of Ames and Combs construction companies will perform the work.
The current widening project is happening just west of another project taking place at Eloy (mileposts 209-213) where ADOT crews are building new lanes, adding a new traffic interchange at State Route 87 and creating a first-of-its-kind dust detection zone. The Eloy project, which began in December, should be completed by fall 2019.
The Eloy widening project also is expected to cause minimal disruption for drivers because the new I-10 lanes and SR 87 interchanges are being built east of the current freeway alignment.
