A £5m project to upgrade Scotland's busiest stretch of motorway is due to get under way.
Work is scheduled to start on the M8 at the end of June
The work will start on a section of the M8 to the west of Glasgow, between the M77 junction and the off-slip for the Clyde Tunnel, on 29 June.
The seven week programme will run into mid-August and will restore a 3km section of the west-bound carriageway.
Transport Scotland said this stretch carried 130,000 vehicles a day and was nearing the end of its useful life.
Paul Reid, Transport Scotland's project manager, said: "We appreciate that any works on such a busy section of motorway will result in a level of disruption.
"But the fact that it carries so many vehicles is one of the main reasons why we must ensure it is maintained to a high standard.
"We are delivering works at the time of year when traffic is at its lightest and there are long daylight hours.
"While the short-term impacts will be delays, the long-term benefits will be a fully reconstructed section of one of Scotland's main links."
A contraflow will operate on the eastbound carriageway and a reduced speed of 40mph will be enforced by average speed cameras.
Bruce Donaldson, Amey's unit manager for south west Scotland, said: "Rebuilding this part of the M8 is complex and challenging, not least because two main motorways merge and there are 14 separate slip roads to consider.
"We're confident our detailed and long-considered traffic and speed management plans, and experience from phase one, will keep drivers on the move.
"Because traffic is much lighter during the summer, delays during last year's job were actually no worse than during an average morning or evening peak outwith school holidays."
Meanwhile, a £1.6m upgrade to two bridges that carry roads over the M8 in Bishopton, near junctions 30 and 31, is due to get under way on 1 July.
The work will last for 12 weeks and will strengthen bridge columns and replace service duct covers on the over-bridge that carries the A8 to Greenock and the over-bridge that carries the C22, Old Greenock Road.
Work will require M8-M898 Erskine Bridge slip roads to be closed to traffic for some periods, with the westbound off-slip to be closed for the first three weeks and the eastbound on-slip to be shut for the second three.
Traffic management will be in place between junctions 30 and 31 and the speed limit will be reduced to 50mph.
