Sea to Sky Highway

Highway 99, BC

In the spring of 2005, the BC Ministry of Transportation awarded a contract for the Design, Build, Finance and Operation (DBFO) of the Sea to Sky Highway 99 upgrade project. The Sea to Sky Highway project was a key component for the 2010 Vancouver/Whistler Winter Olympics.

Project Consortium

ISL was an integral component of the project consortium, providing the highway design for two of the nine segments of this 60 kilometre mega-project. ISL integrated and coordinated with the DBFO team, including the Project Management Group from Hatch Mott Macdonald, the Prime Contractor group from Peter Kiewit Sons, the Operations and Maintenance contractor from Miller Capilano, as well as a wide array of subconsultants.

Highway Improvements

The highway design involved upgrading from a variable speed, two-lane, rugged mountain terrain, rural arterial undivided highway to a four-lane rural arterial divided highway with a consistent speed profile. The design assignment also included three frontage roads, eight parking lots, a roundabout, several stop condition intersections and a signalized intersection.

Showcase Project

The highway will be a showcase for the DBFO process, incorporation of "Context Sensitive Design" and integration of "Collision Modification Factors" used in safety and mobility models.

Award Winner

This project won a 2007 Consulting Engineers of British Columbia Award of Merit for Transportation in Highway Design.
