Boris Johnson, mayor of London, has announced that the Hammersmith
Flyover in west London, which has been closed for three weeks, will
reopen on Friday.

It was shut when serious damage to cables in the structure was
discovered.

Transport for London (TfL) has said one lane will be open in each
direction but it will be closed to HGVs and coaches.

Closure of the A4 route, which is usually used by about 90,000
vehicles a day, has caused serious congestion in west London.

'Reduce disruption'
A steady seepage of salt water into the structure, built in the 1960s,
has weakened the structure, but engineers said it was now safe to take
light traffic.

TfL said the route would reopen "before the rush hour" on Friday but
did not specify exactly when.

Strengthening work will continue for the next four months and drivers
are still advised to "consider avoiding the area if possible".

Once new cables are installed, the flyover will be reopened to all
traffic "well ahead of the London 2012 Games", said TfL.

Garrett Emmerson, chief operating officer for surface transport, said:
"This should significantly reduce the traffic disruption many
thousands of drivers have been experiencing since the flyover closed."
