Wessex Water are fixing a couple of leaks in Combe Street. This work should finish Thursday or Friday. Mostly you should be able to get through, but this is not guaranteed.
The road closed sign at the foot of Long Lane can probably be ignored as access to the Combe St/Bleak St junction seems unaffected.
You can use the very useful website one.network to check on roadworks. Just keep zooming in on your place of interest.
