A National Grid spokesperson said this morning that workers hope to have the problem fixed by rush-hour tonight.

She said: “We were working throughout the night and we should be able to reopen the road mid to late afternoon today.”

Nobody’s gas supply has been affected by the leak.

Two diversion routes, one for HGVs and one for other traffic, can be found on www.warwickshire.gov.uk/roadsandtravel 

UPDATE (4pm Tuesday): Clifford Lane has now been reopened.
