Lane 3 will remain closed in both directions on the M27 between junction 5 (Eastleigh) and junction 7 (Hedge End) in Hampshire following a collision this morning.
Around 400 metres of the central reservation barrier was demolished in a collision at around 7am this morning, which involved an HGV.
The Highways Agency and its contractors are working hard to reopen the lanes as soon as possible, but due to the damage it is unlikely that the repairs will be completed until the evening.
Once the vehicle has been recovered, around 64 new posts and 124 sections of barrier will need to be installed.
Drivers are advised to plan their journeys and allow extra time; delays peaked at 90 minutes for westbound traffic and 60 minutes for eastbound traffic this morning.
Members of the public should contact the Highways Agency Information Line on 0300 123 5000.
Journalists should contact the Highways Agency press office on 0844 693 1448 and use the menu to speak to the most appropriate press officer.
