Operation Transmission – A31 Winchester to Alresford

Last update: February 2021

Scheme overview

Hampshire County Council has worked with Hampshire and Isle of Wight Local Resilience Forum partners to prepare for the United Kingdom’s exit from the European Union on 31 December 2020, and in particular the impact this will have on EU bound freight traffic using Portsmouth International Port.

Preparatory engineering work on a 5km stretch of the A31 dual carriageway between Winchester and Alresford was completed in 2019. From 1 January 2021 the westbound lane of the A31 was temporarily re-purposed to provide a short stay triage point for EU-bound freight traffic travelling to Portsmouth International Port to check that lorries have the correct ‘border-ready’ documentation in place.

The preparatory work involved the installation of two hardened central reserve crossovers near the Ladycroft and Percy Hobbs roundabouts. These crossovers are 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 when a full contraflow is in place. These crossovers, whilst initially being utilised for the Operation Transmission Plan, will also be useful for future traffic management to facilitate highway maintenance operations on this stretch of the A31, avoiding the need for lengthy and disruptive road closures.

The A31 site is a critical element of the Hampshire Local Resilience Forum's (LRF) contingency plan – Operation Transmission - complementing work completed by Portsmouth City Council at Tipner West in Portsmouth.

The A31 has been kept open in both directions at all times with all traffic using the eastbound lane. The speed limit has been reduced to 30mph during this time, and a temporary pelican crossing installed for pedestrians.

Following a review of the plan including the number of lorries with border compliant paperwork, the LRF will be scaling down Operation Transmission during February 2021.

From 18 February, lorries will no longer be required to go through the triage point on the A31 and will be directed straight to the Port.

On 19 February, a litter pick and other minor works will be carried out to ensure the road is left in a neat and tidy condition.

From the morning of 23 February, the contraflow will be removed and the temporary speed restriction removed, except for at the dedicated left turn lane from the Alresford bypass and a short section west of the Ladycroft roundabout – this will be clearly signed.
