I think we will see something like Glenmore- where they add another bridge beside the current one. (or in this case, there are currently two bridges there.)
With the Lafarge only lane, there are 7 lanes of capacity on this bridge. Adding a new 3 lane bridge to give us 5 lanes each way would be a lot cheaper than building a new 10 lane bridge from scratch.
Also, my impression is this is maintenance that is scheduled for every ~20 years or so.
