WILLCOX, Ariz. (13 News) - The Arizona Department of Transportation praised the contractors, law enforcement agencies and its New Mexico counterpart for their efforts after a deadly crash forced an extended closure of I-10 and emergency repairs of a damaged overpass in southeastern Arizona on Wednesday, May 3.
The repairs allowed highway officials to reopen the highway only two days after it was closed.
A temporary structure is in place at the US 191 bridge at I-10 milepost 331, allowing ADOT to make a long-term plan for future steps. At a minimum, the pier, girders and deck where the crash occurred will likely need to be replaced.

A welder who was on site for nearly the entirety of the project told ADOT engineers that he is 80 years old but still at it for his sons company, which was a subcontractor.
Ive retired six times but love what I do, he said.
