As Edmonton proceeds with the massive project to replace the aging Walterdale Bridge, other regions have figured out how to replace a bridge in just one weekend.

CBC’s Tim Adams spoke with Frank Vanderlann, a highway design manager in Ontario, who has worked on several projects using a switching method: the new bridge is built elsewhere, transported in and swapped with the old bridge in hours. He says it saves not only time, but money. 

However, City of Edmonton bridge engineer Shiraz Kanji says that type of operation is not the option when it comes to Walterdale Bridge.

You can listen to Tim’s full interview with Vanderlann and Kanji below.
