Saturday: Guildhall Road diversion

From noon on Saturday, services X1, 1, 2 and 3a will be unable to use Guildhall Road. Those services will divert via Oystermouth Road. First Bus does not give an end time for Saturday's diversion, so passengers should check the live service update before travelling.

Sunday: three services suspended

From 6am on Sunday, services 4a and 92 will run via Christina Street, Uplands and Sketty in both directions between Swansea Bus Station and Singleton Hospital. The Mumbles Road entrance to Singleton Campus will be closed.

Services 1, 2a and 3a will be suspended until 2pm. First Bus says services 1, 2a and 3a will then divert via Christina Street, Uplands and Sketty Lane from 2.30pm until 5pm. Normal service is due to resume when the roads reopen at 5pm.

Race starts at 11am

Welsh Athletics lists the closed-road 10K for 11am on Sunday at Swansea Bay. Its event record gives a race limit of 4,000, with distance markers at every kilometre and water at 5km and the finish.

This is a bus-service guide, not a complete list of every road closure. Drivers should check Swansea Council and live traffic information before setting out.

How we verified this(7)

Written only from the current First Bus and Welsh Athletics primary records in the fact pack.
The seven affected routes, Saturday diversion, Sunday reroutes and three suspended services match the First Bus notice checked at 20:14 BST on 17 September 2026.
Saturday's diversion is not given an end time. The copy does not invent one.
The 5pm reopening is described as First Bus's stated resumption point, not a guarantee that every road reopens at that exact minute.
The story makes clear that it is a bus-service guide and not a complete road-closure schedule because the current council traffic order was not located.
Race date, 11am start, closed-road status and 4,000 race limit match Welsh Athletics.
