iN VIDEO: B.C. Highway’s unknown engineering marvel is the Hollywood Bowl

Feats of engineering ingenuity, like bridges and overpasses, are easy to spot along British Columbia highways.

But there is a structure along B.C.s Trans Canada Highway 1 through the Fraser Canyon that’s little known to the countless motorists who have been driving by it since its construction in the 1960s.

The structure, known unofficially as the “Hollywood Bowl,” is a huge concrete support barrier put in place to support the highway.

Ministry of Transportation and Infrastructure media relations Danielle Pope says the structure was built in 1940. It's not known how many cubic yards of concrete were used in the construction, but it's believed to be the only structure of this shape and size in the province.

Tran BC says there is no indication of its existence from a highway vantage, with the only hint of what lies below being a concrete roadside barrier that changes to a cast-in-place concrete barrier as the vehicle crosses over it.

Pope says the ministry strongly discourages public access to the site due to falling rock and other hazards.

The structure is located between Hells Gate airtram and Farabee tunnel on the Trans Canada Highway through the Fraser canyon.
