VicRoads has assured commuters the cracks that appeared in West Gate bridge will be repaired in time for the morning peak hour.
Road workers are hoping to have Melbourne's West Gate Bridge reopened before this morning's peak.
Two lanes were shut for emergency repairs after cracks up to 20 metres long appeared.
The damage caused long delays to motorists yesterday.
VicRoads is blaming last week's record heat for damaging the bitumen.
It is a bit like getting a tear in your carpet - the floor is sound underneath.
160,000 vehicles cross the bridge daily.
But VicRoads is assuring drivers it's structurally safe.
