A34/M4 Junction 13 (Chieveley) – Weekend Closures/Restrictions

As part of the ongoing works to refurbish the bridges at Chieveley and Welford, we have reached the stage in our construction programme where we need to demolish and replace the bridge beams
at Junction 13.

Due to the specialist working methods and equipment required, including large cranes which will need to sit across all three lanes of the motorway, we will need to close sections of the roundabout
over full weekend periods.
To keep to number of closures and overall disruption to a minimum, work will take place on both bridges simultaneously on these weekends. The scheduled weekends are as follows*:
Friday 8th to Monday 11th May
Friday 29th May to Monday 1st June
Friday 5th to Monday 8th June
Friday 12th to Monday 15th June
Friday 19th to Monday 22nd June
Friday 10th to Monday 13th July
Friday 17th to Monday 20th July
Friday 31st July to Monday 3rd August
Friday 7th to Monday 10 August
Movement at the junction will be restricted as follows:
 Full weekend (9pm Friday through to 5.30am Monday) – the gyratory sections directly below the M4 bridges and the A34 north and southbound approaches to the junction will be closed
- Traffic will only be able to travel from the M4 westbound to the A34 southbound and from the M4 eastbound to the A34 northbound
- Traffic will not be able to travel M4 westbound to A34 northbound, M4 eastbound to A34 southbound, A34 northbound to M4 east and westbound, and A34 southbound to M4 east and westbound
 Weekend nights (9pm to 5.30am) – the M4 east and westbound carriageways, between the slip roads, will only be closed overnight. The M4 will remain open during day-time hours (5.30am to 9pm).
Significant delays are expected during these weekend closure periods, and it is advised that you plan ahead of your journey to allow for extra time or avoid this route where possible.

The gyratory beneath the bridges must be closed due to the high risk of debris falling onto the carriageway below and the need to saw-cut/break-out sections of the deck in advance of lifting operations. There is also a risk of the beams rotating in high winds whilst being lowered by the crane.
Clearly signed diversion routes will be in place, primarily using the A4 between junctions 12 and 14.
During overnight closures of the M4 east and westbound carriageways (between the slip roads) traffic will be diverted off and back on via the slip roads.
Access to the Moto Chieveley Service Area will be available during the closures using signed diversions.
The diversion routes have been approved by the local highway authority and Thames Valley Police and have been selected due to the suitability for all types/sizes of vehicles.
NOTE: There is a weight limit of 7.5t on the local road between Chieveley and Beedon which is unsuitable for heavy goods vehicles. All HGVs must follow the main diversion route.
We would like to apologise in advance for any inconvenience caused by the works and the closures.
The planning of all roadworks is led by safety – for both road users and workers.
