A number of factors can be credited for the reconstruction of 2.56 miles of flood-destroyed Interstate 680 in Iowa in only 33 days: good weather, around-the-clock work and a $2 million early-completion bonus. Crews placed "over 115,000 tons of shot rock" to fill voids in the highway, while other workers prepped the ground, paved the road and completed other work. "Everybody had a common goal, and that was to get the motoring public back on this interstate as soon as possible," says Cork Peterson of Peterson Contractors.
