Here's the latest news from Camden's Head of Engineering:
My colleague has been monitoring the works by Thames Water at the West End Lane junction with Cleve Road. The leak has been repaired and the reinstatement of the carriageway by Thames Water contractors has just been completed.
Following a two hour curing time on this reinstatement the temporary traffic lights will be removed and the road returned to normal signalling.
The Cleve Road is expected to be fully operational by 6.30pm this evening.
