Pierce County Public Works needed 176th Street to be converted from a two-lane road into a four-lane road. In the process, a girder bridge would need to be constructed over the railroad tracks.
The project required an extensive variety of services, including demolition of the existing roadway, evacuation and embankment, and installation of a new storm system. Additionally, GBI made improvements to both the water and sewer systems, constructed a four-lane bridge over the railroad tracks, installed lighting and an extensive traffic control system, and landscaped the entire project.
Removal of the existing road generated a large amount of asphalt grindings. Because exporting them would be expensive, GBI submitted a Cost Reduction Incentive Proposal (CRIP) to reuse the grindings, putting them back into the new roadbed in lieu of importing additional crushed rock. This recycling effort saved a substantial amount of money for the county.
