The flight of steps that is the canal tow-path access at University station are being replaced. I would like to be able to tell you they are being replaced with a wheelchair-friendly, cycle-friendly ramp, like that at Bournville, but of course this being Birmingham, plenty of spurious reasons were found for not doing this. My personal favourite is that this is the site of a Roman fort. The fort has long-since disappeared under a canal, a railway, roads, a car park, and buildings, but this is sufficient to render doing a proper job "completely impossible".
It took persistent badgering of councillors by Push Bikes, particularly Tahir Ali, who seemed annoyed that someone was determinedly complaining about having to cycle along a very narrow path through an unlit tunnel, even though that path is Birmingham's idea of a strategic cycle route and takes traffic off the overloaded A38. Apparently it required negotiation and the seeking of funding.
British Waterways is doing towpath improvements on the canal between Granville St and St James Rd up to mid May. They are also resurfacing the Edgbaston Tunnel tow path with concrete. The tow path will have to be closed.
