Sea-to-Sky Highway Project

The Sea-to-Sky Highway is a 95-kilometre long section of Highway 99 from West Vancouver to Whistler. Set in a mountain landscape, the highway presents complex engineering, traffic management and construction challenges. British Columbia’s Ministry of Transportation (MoT) decided to make improvements to the highway between West Vancouver and Whistler to improve its safety, reliability and capacity. These improvements, completed by 2009, included highway widening and straightening, and other measures designed to reduce hazards, shorten travel times, and increase capacity of the highway. The improvements moved MoT toward its long-term corridor objectives for the highway: to accommodate population growth, economic development in corridor communities, increasing demand for resident and visitor travel, and increased goods movement. Any additional improvements delivered contributed to the fulfillment of MoT’s long-term objectives. In January 2003, Treasury Board approved a maximum $600 million ($2002) capital commitment for improvements to the highway (the Sea-to-Sky Highway Improvement Project – referred to in this document as the overall project). In a subsequent submission to Treasury Board in December 2003, MoT concluded it could provide essentially the same physical improvements at a lower capital cost – for an estimated $600 million in as-spent dollars over the period to 2009 or for a net present cost of $516 million ($2005). These improvements represented a portion of MoT’s long-term corridor objectives and are referred to in this document as the baseline improvements.
