The Shadow Transport Minister told BBC Breakfast: "The whole country wants the Olympics to be a huge success so it is a huge relief that the road is open because of the chaos it would have caused with athletes arriving on Monday to travel to the Olympic Village."

"Given the scale of the problem, ministers need to come out and say they are completely confident the crack is fixed."

M4 Boston Manor viaduct open

The road, which is expected to be one of the busiest routes during the Olympic Games, was shut last Friday between junctions 2 and 3 after cracks were discovered on a viaduct.

But it was reopened to traffic just after 5.30am after engineers completed the "complex" repairs, officials said.

The works to the bridge supports of the Boston Manor Viaduct were due to be completed yesterday.


Repair work on key Olympic gateway 'progressing well'

Repair work on the M4 in west London, the main route from Heathrow to the capital, is progressing well and the motorway should open in the next few days, the Highways Agency said tonight.

Complex work to repair cracks in the Boston Manor Viaduct on the M4 is progressing well but we are still in the critical phase of the works and the reopening of the motorway between junctions 2 and 3 will only take place when it is safe to do so.

Further finishing work will then be required before the road can be reopened.
