Oroville Dam: Phase Two of Spillway Construction May Be More Challenging

Phase two of construction at Oroville Dam — with work on both spillways — might prove more challenging than the first feat, the contractor’s project director said in a media call Thursday. Jeff Petersen, project director for Kiewit Infrastructure West Co., said finishing work for the 3,000-foot main spillway including concrete finishing, joint sealing, drain work and clean up, should be done by the end of the year.
