This $40 million design-build project involved upgrading 7 km of the Sea-to-Sky Highway (Highway 99) between Sunset Beach and Lion's Bay, north of Vancouver, British Columbia, from two to four lanes.
Work involved substantial rock excavation, slope stabilization measures including rock anchors and fences, the construction of mechanically stabilized earth retaining walls, numerous down-slope support structures, storm sewers and paving.
Crews began construction in the spring of 2005 and completed the project in December 2005. All work was performed under existing highway traffic conditions, with minimal traffic closures and rerouting.
