Motorists are facing delays on the M62 as work on a £20m scheme near Pontefract continues.
The work, which aims to relieve congestion, is expected to take until the end of the year to complete.
As part of the Highways Agency project, overnight closures will be in place on the eastbound carriageway between junction 30 at Rothwell and junction 31 at Castleford.
The closures will be in place from Monday, October 6 to Thursday, October 9 and the stretch will be closed from 8pm to 6am each night.
The work is being carried out as part of the government’s £317m national ‘pinch point’ programme and will include new CCTV cameras and automatic traffic monitoring equipment between junction 30 at Rothwell and junction 32 at Pontefract.
Data will then be sent to the Highways Agency’s regional control centre in Wakefield which will be able to apply temporary speed limits on new electronic signs which will be installed.
There is a 50mph speed limit in place on the stretch and the hard shoulder is also closed.
Thomas Howard, Highways Agency assistant project manager, said: “Once this work is completed the new technology will relieve congestion and improve safety on this busy section of motorway whilst providing drivers with more information.
“During the work we advise drivers to check local traffic conditions and leave extra time for their journeys if necessary.”
As part of the works, the entry slip road of the eastbound carriageway at junction 30 at Rothwell will also be closed on the same dates.
The Highways Agency is also carrying out a £120m scheme on the M1 between junction 39 and junction 42 near Wakefield.
