There will be overnight closures, narrowed lanes and reduced speed limits on the M27 near Southampton until Spring 2015 as part of ongoing road improvements.
The two major improvements will begin next week as part of the government's £317m programme on motorways and trunk roads.
The enhancements will eventually reduce congestion, increase safety and improve journey times.
The work will start on Monday 4th August from Stoneham lane eastbound from the A335 onto the eastbound entry slip road.
Improvements to junction 3 will start at the end of September, after the Southampton Boat Show, and will see the westbound exit slip road and southbound M271 widened to three lanes.
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.”

Following a severe incident at Wimbledon this morning, it was necessary to significantly reduce the number of trains through Wimbledon while this incident was ongoing.
Trains and crew that were scheduled to work on trains around our network were not able to get on to these trains due to the disruption. This has had a further impact on our service recovery and spread the problem from our Suburban services to our Windsor services (Waterloo to Staines).
We have reinstated trains on each line of route with the exception of London Waterloo to Salisbury trains which will continue to start from Basingstoke in both directions until 1720.The 1720 London Waterloo - Exeter St Davids departure will be the first service to run its booked route.
Whilst we work to introduce services back into normal operation, customers may see further last minute alterations. Please check before you travel. Disruption to all services on the South West Trains network can be expected until the end of service today.
