The Arizona Department of Transportation (ADOT) recently announced that all lanes of the Houghton Road interchange at I-10 in southern Arizona are now open.
The $24.4 million project features a diverging diamond interchange, a design that will improve safety and traffic flow in a rapidly growing part of southeast Tucson, according to a news release from ADOT.
Unlike a traditional diamond interchange, each direction of Houghton Road traffic temporarily shifts to the left while crossing the freeway. This allows for left turns onto the entrance ramps without waiting at an additional traffic signal.
