A31 Winchester/Alresford

Scheme overview

Preparatory planning works in the event the UK exits the EU without a deal

Preparatory work has been completed on a 5km stretch of the A31 dual carriageway between Winchester and Alresford to provide an area that may be needed for holding freight traffic waiting to use Portsmouth International Port for cross-channel services to France or Spain. This has been a critical element of the Hampshire Local Resilience Forum's (LRF) contingency plan, complementing ongoing work at Tipner West in Portsmouth.

Preparatory engineering work to install crossovers at the Ladycroft and Percy Hobbs roundabouts is complete. The crossovers are two new short sections of carriageway that have been constructed across the central grass verge to allow traffic to move safely from the westbound lane to the eastbound lane in the event that a full contraflow becomes necessary. Both new crossovers will only be used when they are required.  These crossovers are essential for the contingency planning for managing lorry traffic, but will also be useful for future traffic management, for example to facilitate major maintenance operations on that stretch of the A31, avoiding the need for lengthy road closures.

Creating this managed holding area avoids the potential for traffic disruption on Hampshire roads due to increased use or delays at Portsmouth, in the event of the UK exiting the EU without a deal. The plan will ensure that the A31 is kept open in both directions with all traffic using one carriageway thereby releasing the other for use as a holding area.

Following the results of last week’s General Election and clear intentions from the new Government, the LRF has now stood down its plans for Operation Transmission as the likelihood of the UK leaving the EU without a deal on 31 January 2020 has significantly reduced.

The LRF, and the County Council, will continue to review and assess planning assumptions as the Brexit process concludes through 2020.
