Bridge Collapse

Thursday

The entire span of the Interstate 35W bridge collapsed Wednesday evening in Minneapolis. The bridge was loaded with rush-hour traffic and dropped more than 60 feet into the Mississippi River. At least seven people were killed and more than 60 were injured.One section of the bridge lay flat in the river, with cars parked on the rolling pavement.
A 2001 evaluation of the bridge, prepared for the state transportation department by the University of Minnesota Civil Engineering Department, reported that there were preliminary signs of fatigue on the steel truss section under the roadway, but no cracking.

If they were paving the surface of the bridge with asphalt were they useing a breakdown roller on the asphalt? You CANNOT use a vibrator on a breakdown roller on a bridge deck.
