Thames Water 'sorry' as leaks close Regent Street again
Regent Street in London's West End has been closed again so repairs can be carried out to a collapsed sewer and leaking water main.
The busy shopping street was shut for three weeks earlier in the year due to a burst water pipe.
Now southbound lanes between Oxford Street and Little Argyll Street have been closed, causing 22 bus routes to be diverted.
Thames Water said it hoped to have work done by the end of the Bank Holiday.
But a spokesman for the water firm warned work could take longer if investigations threw up other problems.
The issue came to light following reports of water entering the basement of a nearby shop and an old communication tunnel.
Thames Water said if left it could lead to a "catastrophic burst".
It is unrelated to the previous problem.
Damian Crawford, Thames Water's network manager, said: "We are really sorry to have to shut part of Regent Street again, particularly given that just two months ago we were saying no-one would thank us if we were back on the same street in a few months' time.
"We fully understand people's frustrations and we really are working as hard and fast as we can to get this new set of problems sorted out.
"The reality is that a third of the pipes under London were put in by the Victorians - and when things get old they break."
The following bus routes have been diverted as a result of the repairs: 3, 6, 8, 12, 13, 23, 25, 55, 88, 94, 139, 159, 453, C2, N3, N8, N13, N18, N55, N109, N113, N136.
