A 77-year old bridge over Highway 400 was demolished on Oct. 1, making way for new and improved infrastructure.

The original two-lane Highway 89 overpass, a single-span cast-in-place with boxed girders and steel trusses, is being replaced to accommodate the future widening of Highway 400.

A rapid demolition by Priestly Demolition Inc. completed the the rapid demolition in record time. Approximately 150 truckloads of concrete were hauled away from the site over the week, along with steel and rebar.
