First I've heard of this myself, but personally, I'm not a huge fan of putting bike lanes on busy commuter streets. I always prefer if they are on the quieter streets...makes for a safer/nicer experience for everyone.
Ah the memories... the saga of the 1st Street SE idea dates back to the original cycletrack debates in the late 2000s.
It was proposed as a key corridor, but ultimately, it was sacrificed as a corridor to win over a few Council votes, resulting in the cycletrack being approved (and continues to be popular to this day).
The problem is that there aren't any corridors that aren't busy commuter streets to access downtown from the south. If we want cycling/scooter access to the central part of downtown you actually just need to reallocate some space (or build a new active modes only underpass, which from the debate on 11th is any indication, many Calgarians can't comprehend).
We only have 8 options to choose from, with pros and cons:
- 11 Street SW: remote location too far west from major population or job clusters. Painted bike lane already, and relatively low importance to car traffic.
- 8 Street SW: busiest pedestrian and transit underpass into downtown, getting upgrades to include new cycling lane in the future. Moderately important to car traffic.
- 5 Street SW: central to jobs and population and has a cycle track already! Busiest non-river pathway segment of the cycling network - central to jobs and population. Great connectivity. Obvious in why it's so popular.
- 4th Street SW: great central location with hugely over-built car capacity, and no traffic scenario that can use all 4 north-bound lanes - a great candidate to repurpose space. problem is we don't need it - cycling lane is on 5th Street SW already.
- 1st Street SW: great central location, tight geometry and little space to work with though. Relatively unimportant to cars, but heavy bus traffic.
- 1st Street SE: great central location, space to work with. Important for vehicles, but so wide it actually doesn't need 4 lanes the whole way.
- MacLeod Trail SE: great central location, high car traffic with loads of turn movements both west and east.
- 4th Street SE: remote location away from population and jobs. Has cycling lane already.
When comparing all the factors, it's why 1st Street SE always floats to the top. It's central and has the capacity to reallocate a lane. Most traffic doesn't turn east bound, leaving the eastern lane relatively unimportant to maintain traffic flow. The whole corridor is 4.5 to 5.5 lanes wide, but due to inefficient design it only really needs 3 lanes to accommodate traffic.
With proper design and barriers it's a pretty good project.
The problem with 1st Street is well documented too - it doesn't "feel" that is can handle a bike lane to drivers or politicians.
"Putting a bike lane on MacLeod Trail" is seen as one of the most out-of-touch things someone can do, despite this 10 block stretch having the excess capacity for vehicles, high demand for bikes, and having nothing in common to the suburban car sewer that is in everyone's collective memory of "MacLeod Trail".
That's enough to kill it - anti-bike south Calgary suburban Councilors can always find a way to rally against it.
