All three M1 lanes re-opened

The Highways Agency has announced that there are now three lanes open in both directions between junctions 1 and 4 of the M1 north of London, following an intense fire on Friday that necessitated road closures.

The southbound lanes opened at 5.10am today; the northbound lanes opened at 6.20am. This comes as work continues to repair huge damage caused by a fire at a scrapyard under the motorway last Friday.

An 80.5km/h (50mph) speed limit is in force over the viaduct for safety reasons — a rise from the 64km/h (40mph) limit previously in place.

The Highways Agency said it is likely there will be a need for further closures in the future to enable permanent repair work to be undertaken.

This will be planned to minimise disruption as far as possible, it said. Following the fire, extensive investigation, assessment and structural reinforcement work has taken place non-stop.

One lane was opened northbound at 6.40pm on Saturday, with a second northbound lane opened by 1.00pm on Sunday. Two southbound lanes were opened at 4.00pm on Monday.
