Given that this portion of the trail is likely be the busiest bikeway in the region by far, a better surface is required. I fully expect to see this whole are redesigned within a few years as the challenges of mixing that many people walking & biking become acute.
EDIT: The bike lane "metres away" is an extension of the trail you see here, not a replacement.
With the bridge costs already vastly over budget there is no way the CoV should consider any sort of redesign. Cyclists can share the road with cars if this set-up doesn't work for them.
I am not sure I ever suggested the bike lanes were a replacement for anything, with perhaps the exception of common sense or money well spent.
