Worth noting also that the Lions Gate Bridge in Vancouver, a bridge designed by the same engineers, Monsarrat and Pratley, and almost identical to the MacDonald Bridge, is 17 years older and there are no plans to replace it, it was also re-decked in 2001 by the same firm that re-decked the MacDonald Bridge. I've also heard nothing indicating that the Lions Gate Bridge is nearing the end of its life. Certainly a couple of very robust bridges.
