M3 J2-4A Managed Motorway 19 May 2017
Upgrade of the existing M3 between junctions 2 and 4a to allow dynamic hard shoulder running (use of the hard shoulder as an extra lane at peak times). Where necessary, junction capacity will be increased to prevent traffic queues building up on the slip roads and encroaching on the main carriageway.
This scheme was introduced as part of the National Infrastructure Plan in autumn 2011.
A21 Castle Hill-Pembury improvement 8 May 2017
Upgrade of the A21 between the A26 near Castle Hill and the Longfield road roundabout near Pembury to a dual carriageway standard. This is one of the most congested sections of road and is a high priority. Longfield road roundabout will be grade separated, giving access to a new regional hospital. This section of road, on average, carries 46,000 vehicles a day.
There will also be another minor road grade separated.
A30 Winchester Road Roundabout improvements 24 April 2017
As part of a programme of improvements to congested junctions around Basingstoke, the first of which was the M3 J6 Black Dam Improvements, the A30/A340 Winchester Road roundabout will be widened and the approaches improved.
Three of the four approach roads are to be widened and have traffic light controls added, with additional lanes created on those approaches and on the gyratory, increasing capacity around the junction. Drainage improvements will also be made to prevent the junction flooding.
M25 J25 Improvement 31 March 2017
An upgrade of the existing roundabout and sliproads at the junction between the M25 and A10. The scheme is intended to improve the performance of the junction and improve reliability for all traffic, specifically reducing the regular queues on the sliproads that tail back on to the mainline of the motorway. It also aims to reduce the number of collisions at the junction, improve pedestrian and cycle facilities and increase overall capacity.
At present, three options are proposed, all of which will involve improving the existing layout.
M4 J3-12 Managed Motorway 22 March 2017
Upgrade of the existing M4 between junctions 3 (Hayes) and 12 (Theale) to Smart Motorway, with the hard shoulder converted to an extra traffic lane for most of that length.
Unusually for a Smart Motorway scheme, bridge widening and replacement works will be carried out to provide extra space on parts of the motorway that presently carry three lanes with no hard shoulder. The M4 Slough and Maidenhead Bypass sections were subject to "rapid widening" in the 1970s which left the motorway with a discontinuous hard shoulder through bridges.
A27 Chichester Improvement 8 March 2017
Upgrade of the current A27 Chichester Bypass, which suffers from chronic congestion and unreliable journey times. The existing road has five roundabouts and one signalised junction, and is one of the major barriers to the provision of a free-flowing route along the south coast.
Highways England have refined the possible options to three proposals, and a preferred scheme will then be selected from these three as part of a public consultation in spring 2016.
