Sea-to-Sky Highway, Canada

Highway 99, also known as the Sea to Sky Highway, or in its southern reaches the Squamish Highway and/or Whistler Highway, is the major north-south artery running through the Greater Vancouver area of British Columbia from the US border and beyond up Howe Sound through the Sea to Sky Country to Lillooet and connecting to British Columbia provincial highway 97 just north of Cache Creek. The number of this highway is derived from the old U.S. Highway 99, which the highway originally connected with at the Canada-U.S. boundary. The highway currently connects with Interstate 5 at the international border.

The "Sea to Sky Highway" section of Highway 99 has a checkered history. Built on a steep cliff overlooking Howe Sound, it was a two-lane undivided highway with no outside barrier. Many motorists have lost their lives on it due to inclement weather, poor visibility, speeding, passing slower vehicles, or drunk driving. (Local media have called it variously the "Killer Highway", the "Highway of Death", and the "Drive-to-Die Highway".)
