Interstate bridge replaced in just 55 hours (video)

The video you see above was captured during a very ambitious bridge replacement project in Massachusettes. It was a collaboration project between J.F. White Contracting Co., Klewit Construction, and Testa Corp. Dismantling and Site Contractors.

This was no small bridge, having 4 lanes and 3-tiers. The timeframe for demolishing and replacing the bridge was just 55 hours over a single weekend. The initial demolition took just 10 hours before moving on to precast erection and placement phase, and the eventual complete replcement of the bridge within the timeframe.

The replacement formed part of a larger project called 93Fast14, which saw 14 bridges completely replaced in just 10 weekends. Now that's efficient.
