The path along 23rd Ave connecting Arboretum Park to the path they added along Hillsdale is under construction now. The fence at the tree nursery is being moved back to make space. Since its being built by Wascana Park instead of the city it will almost certainly have lighting installed, though that would be under a separate contract and may not happen this year.
Last year when the city rebuilt the McCarthy bridges at Wascana Creek they added short connector from the sidewalk to the Devonian pathway on the north side so you can jump between the north and south side of the creek. Last night I discovered that they ripped it out and moved it 30 feet north. I ended up barreling down the embankment where the path used to be, fun!
I think the change was made to address an incompetent oversight in the design of that project. McCarthy has a parking lane that abruptly disappears at the bridge and reappears after it, which means they can never ever put a bike lane there. So when they did the paving this year they added a curb ramp further back before the road narrows expecting cyclists to ride down the road, get on the sidewalk to cross the bridge then get back on the road on the other side. The less than a year old path was ripped out so they could align it with the new curb ramp.
