It's such a shame that the NCC never did follow through on the idea to consolidate STO and OCTranspo. All of these problems would be solved and it would open up serious new opportunities for better/more beneficial alignments like this one:
The Ottawa river is shallower in this part. The depth is not too deep as to exceed the maximum grade of most LRTs (including Citadis Spirits), the alignment is more natural, and the infrastructure would genuinely benefit both Ottawa and Gatineau without duplicating and already existing alignment.
