Freeway workers don't know what made a bridge under construction in Mesa collapse Thursday,sending 52-ton concrete girders tumbling onto the dirt and into a canal below.

No one was injured in the accident that occurred about 8:30 a.m. on the Loop 202 near Power Road in northeast Mesa.

The contractor, Pulice Construction Inc., will lead an investigation how nine of 11 beams laying horizontally atop the 25-foot bridge rolled off after three weeks of sitting atop pier caps awaiting a diaphragm to link them together.
