Part of the A30 will be closed overnight from 7pm today (Friday) for emergency repairs.
It follows a major lorry fire on Wednesday, which has damaged the surface of the road.
Although the closure involves a section of the dual carriageway in Devon, it will affect many people attempting to travel in to and out of Cornwall tonight.
The closure will be in place from 7pm on Friday (June 21) until 6am on Saturday (June 22), between Sourton Cross and Lifton Down.
On Wednesday National Highways put out notice of an emergency road closure on the A30 westbound between the A386 Sourton Down and the A388 at Launceston due to a lorry fire.
The authority warned that clear-up work was “likely to take some time”.
The road reopening yesterday (Thursday) but with one lane remaining closed through the day, for emergency resurfacing works to take place on it.
The lane remains shut today (Friday) and now the whole of that section of dual carriageway westbound will be closed fully again tonight for the repairs to be finished.
A diversion route will be in place during this time, using the old A30.
The authority said: “National Highways is advising drivers that the A30 will be closed overnight for emergency repairs following a lorry fire.
“The westbound carriageway will be fully closed from 1900, 21 June to 0600, June 22 between Sourton Cross and Lifton Down.
“Lane one westbound is currently closed and will remain so throughout the day.
“During the overnight closure, a signed diversion route will be in place, using the old A30 through Bridestowe, Lewdown and Lifton.”
