A major scheme to upgrade the A326 in the Waterside has moved forward, with a planning application now submitted for junction upgrades, new dual carriageway sections and walking and cycling improvements.
The proposals include a mammal tunnel for otters beneath the Bartley Water, seven new traffic light-controlled crossings, new roundabouts, extra traffic lanes, environmental mitigation measures and a “School Street” outside Marchwood CofE Infants School.
As previously reported, Hampshire County Council gave the green light for the £187m A326 Waterside improvement scheme.
The scheme would see 2.6km of the A326 widened from single to dual carriageway between Michigan Way and Cocklydown Lane, while a further 1.5km would gain an additional southbound lane between Hounsdown and Staplewood Lane.
Eight junctions are proposed for improvement along the A326, including Michigan Way roundabout, Netley Marsh, Fletchwood Road, Monkton Lane, Cocklydown Lane, Staplewood Lane, Twiggs Lane, the new Pilgrim Inn double roundabout junction, and Main Road.
The Pilgrim Inn proposal would create a new key access point for Marchwood, while Main Road roundabout would be signalised and widened with additional lanes and improved turning arrangements.
Active travel measures include three modal filters to reduce through-traffic while maintaining access for walking and cycling.
These include closures and restrictions at Staplewood Lane (west) and Twiggs Lane (north), the latter supporting a “School Street” outside Marchwood CofE Infants School.
A series of new toucan crossings are also proposed to improve links between communities on the eastern side of the A326 and the New Forest National Park to the west.
Shared footway and cycleway routes would also be widened.
Environmental mitigation measures form a significant part of the project due to proximity to sensitive habitats, ancient woodland and protected environmental sites.
Among the ecological measures is a dry mammal tunnel beneath the A326 at Bartley Water to allow otters to cross during flooding.
Otter-proof fencing would also be installed to guide animals towards the crossing point.
The project also proposes wildlife ponds, bat-friendly street lighting, native tree planting, biodiversity enhancements and new drainage systems.
Several structures would be altered or introduced, including extension of the Ashurst Culvert at Bartley Water with flood relief pipes, widening works to Ashurst Bridge Road and a new independent bridge at Ashurst Railway.
Noise barriers would be installed at several locations to reduce the impact on nearby homes, while sustainable drainage systems and flood alleviation measures would be introduced, particularly around Bartley Water.
Hampshire County Council said construction management plans would be developed to minimise disruption.
Public consultation on the proposals is open until 17 June 2026, with comments able to be submitted via the council’s consultation portal.
