MAJOR work begins this week in a bid to reduce congestion and improve journey times on the M27.
The Highways Agency is starting upgrades to junctions 3 and 5 as part of a £317m government-backed scheme.
The work at both junctions will see additional lanes added on some approach roads and sections of the roundabouts, as well as new traffic signals.
There will be narrow lanes with reduced speed limits and overnight closures until the project is completed in spring next year.
Ed French, from the Highways Agency, said: ‘The additional capacity on these two busy junctions will allow the roundabouts to work more efficiently to reduce congestion and improve journey times. We will widen certain approaches and install new traffic signals to improve the flow of traffic for the thousands of drivers at both junctions.
‘We have planned the work carefully to minimise disruption and will carry out as much of the work as possible overnight, when traffic flows are at their lowest. I advise anyone wishing to use either junction to plan their journeys and to allow extra time.’
Work at junction 5 begins today.
