It looks to me the current work has finished, the JCB and cabins have left the site. However it looks like this route is "permanently" closed. They have put a sign in at each side of the clousure pointing to take the steps by the station:

There is a new sign up - stopping order refers to this I think? www.edinburgh.gov.uk/downloads/do...

Cycling home with the boys yesterday

Unusual delay on the commute to work this morning. #edinburgh #commute #unioncanal

The path at the North end of the Edinburgh Arena Construction site is now fenced off, doesn't seem like the contractors have made any effort to signpost this. Diversion up the steep offroad steps up to the Station or right via South Gyle Crescent seem to the options. #edtravcyc

#EdTravCyc I discovered yeaterday, that the really useful route between Port Hamilton and Morrison Street is closed.

The route shown on the map below is effectivly closed.

Early cold start to the day, with an unusual train into London for the first working day of 2025.
