Operation Transmission

About the A31 Short Stay Triage Point

The A31 triage point will be partly decommissioned from 23 February 2021

  • Remaining Infrastructure – Some infrastructure such as welfare cabins, the document checking platform and toilets will remain, should there be a requirement to re-mobilise the triage area over the next few weeks, however, these will be removed towards the end of March 2021. The future removal of these last remaining items will require an additional over night road closure on the westbound lanes.
  • Road condition – work to repair the road where the worst potholes occurred will take place to make it safe and highways teams will return later in the year in better weather conditions to carry out some more substantial patching
  • Crossovers – The crossovers constructed to facilitate the contraflow will remain in their current state for the foreseeable future, protected with concrete barriers. Further options will be considered to protect these for their potential use for highway maintenance works in the future.

Planning and Engagement

Implementation plan start date

The preparation works start on 14 December, with various night-time road closures and day-time lane closures needed at different times to implement these. Signs will be put out in advance to notify people of any closures needed. The actual contraflow will be in operation on 30 December and the site will be fully staffed from 31 December.

Journey times on the A31 between Alresford and Winchester

There will be a short increase in travel time between Winchester and Alresford, due to the reduced speed limit of 30 mph. Advance notification of this has been given to residents and businesses along the route, and information communicated more widely via the media.

Planned public communications

Up to date information is available via the County Council’s web pages.

The County Council, alongside partner organisations, has carried out extensive stakeholder engagement, including with those representing the communities; direct communication with residents and businesses closest to the route; information to the local media and on the County Council’s web pages; and will continue to issue communications as required to keep communities informed.

Affect of UK regulation changes in July 2021

The current guidance from Government is that the plan is required for a ‘realistic worst case scenario’ which is a period of 12 weeks. The changes to regulations expected in July relates to imports, therefore there are no anticipated impacts on traffic outside of Portsmouth International Port.

Impact on local visitor numbers to Alresford and the impact on local businesses

All access points to Alresford are being maintained as they currently are, and there is no anticipated impact on local businesses in the area.

Local Traffic Control

Access for traffic on the A31 from Avington and Ovington and turning onto the A31

Traffic can still access the A31 from Avington & Ovington. However, due to the contraflow, only left turns can be carried out from these junctions.

Access arrangements for properties on the northern side of the A31

Access will still be possible to all properties on the north side of the A31. However, due to the contraflow, there are only left turns into and out of properties - it is not safe or permitted to turn across the central line of cones/cylinders.

Safety wands/barriers

There are central cylinders positioned to separate east and westbound traffic in the contraflow with these spaced close together at junctions to prevent right turns.

Rodfield Lane access onto the A31

There is one controlled crossover at Orrs Meadow. There is no access from Rodfield Lane onto the A31, however, the road remains open in both directions.

Arrangements to prevent the B3047 being used as a rat run from Alresford/Winchester

As the A31 will be open in both directions at all times, no arrangements have been put in place for other routes surrounding the A31 to prevent traffic from using them, as measures such as these could result in disruption to local traffic that usually uses these routes.

Arrangements for public transport and the school buses into Winchester

There will be no changes to existing public transport and school buses, these will run as they currently do and will continue to use the Orrs Meadow bus stops. Our teams are keeping the bus operators informed of the plans so they can make any operational decisions needed.

Getting Lorries to the A31


There is extensive signage on the strategic road network to direct freight to the site, primarily via the M25/A34/M3 via Junctions 9 of the M3 and to the A31. Freight travelling from the west of Southampton along the M27 will be directed north to Junction 10 of the M3 to then head to the A31. There is some signing on the A331 and A31 (starting at the Hogs Back) to direct local freight to the site using the A road network, although traffic numbers here are expected to be low.

Access for lorries to the HGV triage area

There is no access to the triage area from the Ladycroft roundabout. All freight accessing the triage area has to travel to the Ropley/Bishops Sutton roundabout, turn around and travel back to the Ladycroft roundabout and access the triage area via the dedicated filter lane. All other traffic will use the lane leading onto the roundabout.

Lorries in the triage area at peak times

Freight is expected to arrive at the A31, two to three hours prior to their booked sailing times. This is very similar to how they currently turn up at the Port. The common sailing times at both the morning peak and evening peak means allowing this time will ensure they are avoiding peak traffic times by arriving at the A31 around 5 to 6am and 8 to 9pm.

Lorry checks

The average time the checking process should take 3 to 4 minutes per lorry.

Freight Drivers

Number and distance apart of drivers’ welfare facilities along the A31 HGV triage area

Welfare facilities are located at nine areas, which are all existing crossovers and paved areas. Alongside these ‘Portaloo’ style toilets will be rubbish bins and a floodlight.

Cleaning of toilet facilities

The cleansing regime for the toilets is every few days and is in line with national safety guidance for outdoor events.

Making the site and facilities COVID safe

The site will be managed in accordance with the recently published Government guidance on Working Safely during Coronavirus (COVID-19) – Construction & Other Outdoor Work.

Instructions for waiting drivers

Upon having documents checked, the drivers will be instructed to remain in their vehicles unless they are using the facilities, and to turn off their engines. It should be noted that lorries would not usually leave engines idling as this is against their business model which is based on fuel usage. Instruction guidance is provided in 10 languages.

Food facilities

The existing burger van located at the Orrs Meadow layby will be allowed to remain, no other traders have been given permission to operate.


Preventing littering

Skips with netting are being located next to ‘Portaloos’ for the disposal of rubbish. These will be monitored and will be emptied once they are half full.

Air quality monitoring and mitigation

As this is a temporary arrangement, no measures have been put in place to monitor air quality.

Staffing and running of the triage point

Triage point area

There will be staff on site 24 hours a day.

Numbers of staff on site

There will be 14 staff and an additional Police presence.

Shift patterns

There will be two shifts of 12 hours each, approximately 8am to 8pm with handover.

Staff roles

There will be an overall supervisor, traffic management maintenance operatives, staff guiding freight at the site entrance, Orrs Meadow and the site exit and also staff undertaking the documentation checks.


The Police will deal with any nuisance.

Infrastructure provision for staff

Staff will have their own welfare with cabins for both operatives and the Police, all will be provided with power and water, all following COVID guidelines.

Staff compound location

The main staff compound is located at the entrance to the site at the Ladycroft roundabout, there is also a welfare cabin at Orrs Meadow and one at the exit of the triage area towards Percy Hobbs roundabout.

Staff arrival and parking

Staff will arrive by cars and will park on site.


The generators for the floodlights charge the batteries during the day so they will run silently at night. The welfare cabin and floodlight at Orrs Meadow will be solar powered. There will be generators running at the staff area at the entrance to the site at the Ladycroft roundabout.
