Series of wide-load trucks to follow I-10

Delivery of girders for the new bridge being constructed on U.S. 70 over the Gila River in Graham County will require a series of oversized loads to travel from Phoenix, past Casa Grande and beyond Tucson on Interstate 10 beginning Thursday.

The new 15-span bridge, located one mile west of Bylas on the San Carlos Apache reservation, is being constructed by the Arizona Department of Transportation to replace the existing bridge that was built in 1957.

The delivery of 120 precast concrete girders will take place over 15 weeknights. The first deliveries will begin leaving the Phoenix facility where they are cast shortly after midnight on Thursday with eight trucks departing at 15- to 30-minute intervals. The trucks, measuring 190 feet long, 10 feet wide and 14 feet tall, will carry one girder at a time and will be escorted. They will follow Interstate 10 eastbound from central Phoenix past Casa Grande to east of Tucson.

No deliveries will be made on weekends. Motorists traveling on the route are advised to be alert for slow-moving oversized loads and to drive with caution.
