Highways England plans to upgrade Winchester junction in Hampshire


Highways England, a government-owned company for operating, maintaining and improving England's motorways, is planning to upgrade one of the motorway junctions on the M3, junction 9 at Winchester in Hampshire.

As per the plan, Highways England intends to redesign Winchester junction, where the M3 interchanges with the A34, to create dedicated free flow lanes.

The work will allow drivers to travel freely between the two roads, the M3 and the A34, while avoiding the use of junction roundabout.

Under the plan, the roundabout will be redesigned into a new ‘dumbbell’ layout in a bid to increase capacity and improve safety.

Highways England senior project manager Neil Andrew said: “More than 6,000 vehicles use this junction each hour during peak times and making the junction free flow will stop queues backing up onto the main carriageway and reduce the risk of collisions.

“Not only will the improvements help to separate local and long-distance traffic, we are also improving access for pedestrians, cyclists and equestrians.

“The plans are on show until 27 August and I encourage anyone interested to come along to one of our exhibitions or send us their feedback.”

The improvements to the junction include creating a new free-flow link road between the M3 and A34 to reduce traffic; and widening the M3 from two to four lanes between the south-facing roundabout slip roads and the new free-flow links with the A34.

It also includes development of new subways through the junction to create a continuous, segregated route between the South Downs National Park, Winnall and Abbots Worthy.

Hampshire County council deputy leader Rob Humby and executive member for Economy, Transport and Environment said: “This is a critical junction on the national road network as well as locally, and the planned improvements will help to separate strategic and more local traffic at junction 9, as well as improving facilities for cyclists and pedestrians.”

The M3 is the main road between London and the Solent Ports. The A34 serves as the main corridor between the south coast and the Midlands.
