Work on the safety barriers on the M3 is set to begin soon.
National Highways is making the improvements while the work on the smart motorway is paused.
It will be completed between Junction 12, for Eastleigh, and Junction 14, for Southampton.
The work is due to start on June 6, and will take six weeks to complete.
Despite the work taking place overnight, diversions will be in place for people travelling at that time.
A statement from National Highways said: “The M3 junction 9 to 14 all lane running upgrade has been paused. However, we’re still going to carry out important safety barrier improvements on that stretch of motorway and we’re now getting ready to start on the first section of work which will be between Junctions 12 and 14 in both directions.
“From Monday June 6, for about six-weeks, we’ll be creating a safe area to work in and to do this we’ll be changing the road layout. This involves removing the existing road and installing metal barriers on both carriageways between Junctions 12 and 14.
“This work will be undertaken overnight. There’ll be closures of lanes, entry and exit slip roads and carriageways. When we close the motorway or slip road, a clearly signed diversion will be in place.
“We’ll update our website further when we move into the next section.
“As standard practice for roadworks, once the traffic management is in place mandatory average speed restrictions will be implemented, temporary CCTV cameras will be activated and free recovery service within roadworks will be provided.”
In a Facebook post, Winchester MP Steve Brine said: “After the suspension of the smart motorway scheme, many constituents may have some questions about the work will be occurring on the M3, between J9 and J14.
“National Highways will be carrying out important safety barrier improvements. This will cause some disruption during the nights as they start their first stage of work on 6th June, overnight for six weeks.”
