The Highways Agency starts a £150,000 scheme to remodel an exit slip road from the M1 motorway at Wakefield next week.
Work on the slip road, at junction 40 of the M1, is due to start on Monday and is expected to take a month to complete.
The scheme involves changing the lane destinations on the slip road, renewing traffic signs, installing safety barriers and some resurfacing works.
All the work will be carried out overnight between 8pm and 6am and the project is due to be finished before Thursday, December 20.
The northbound exit slip road will be closed during the overnight works.
The agency has said drivers wanting to leave the M1 at junction 40 will be re-directed up to junction 41 where they can join the southbound carriageway, travel back down the motorway and use the southbound exit slip at junction 40.
Meanwhile, a series of lane closures have been implemented to keep a £150m project to upgrade the M62 on track.
One carriageway of the M62 is being closed between junctions 28 at Tingley and 29 at Lofthouse every weeknight from Monday, expected to last until mid-December.
The closures are part of a major scheme to create the region’s first managed motorway scheme between junctions 25 and 30 to relieve congestion.
It will use electronic displays on gantries to set speed limits and open the hard shoulder as a lane on some stretches.
The hard shoulder will also become a permanent extra traffic lane in both directions between junctions 25 and 26, and westbound only between junctions 30 and 29.
Work on the managed motorway scheme, which is due to open in 2013-14, began in October last year. Traffic will be diverted via the M621 and M1 during the weeknight closures, from 8pm to 6am.
Full motorway closures will also take place overnight between junctions 29 at Lofthouse and 30 at Rothwell on Saturdays until mid-December.
All traffic will be diverted via the M1, A639 and A642, from 8pm to 9am.
