A339 Improvements

This project involves highway improvements along the A339 between the Pinchington Lane Roundabout and the entry to the Household Waste Recycling Centre.

The A339 will be widened on both sides to make room for two lanes in either direction and a new traffic light controlled junction will be constructed. The new junction will connect the A339 to a new link road that will serve the new Highwood Copse Primary School and will include a pedestrian crossing to allow users to safely cross the A339. Further works included in the scheme are major utility diversions on both sides of the A339, significant surface water drainage works and footway construction.

Initially, the new junction will only serve the school, but the junction and link road have the potential to provide an access route to housing in that area if an appropriate scheme comes forward for a residential development on the adjacent site.

The project is part funded by Thames Valley Berkshire Local Enterprise Partnership's Local Growth Deal Funding.

Works are due to start in October 2020 and last until Spring 2022.

Project Update - Upcoming Road Closure

Road closure from 8pm on Sunday 3 January 2021 through to 6am on Monday 4 January 2021.

Written on: 16-12-2020

At the beginning of January 2021, West Berkshire Council's (WBC) term maintenance contractor Volker Highways will be starting highway improvements on the west side of the A339 from Pinchington Lane Roundabout to south of the Household Waste Recycling Centre (HWRC). These works are currently scheduled to last until the summer of 2021 and will include major utility diversions, fully-upgraded surface water drainage system, carriageway widening and other civils elements.

In order to protect the workforce undertaking these improvements, a protective guardrail system will be installed on the A339 northbound. This will reduce the carriageway to one lane in each direction. So as to reduce disruption, the protective guardrail will be installed overnight and therefore a full road closure is required from Pinchington Lane Roundabout to The Swan Roundabout.

The closure will be permitted from 8pm on Sunday 3 January 2021 through to 6am on Monday 4 January 2021. A signed diversion route will be in place whilst the road closure is operational.

Access for emergency vehicles on a blue light will be permitted at all times.


End of Week 10

This week on site, the new link road junction was completed up to the binder level.

Now the junction head has been completed, the works have moved closer to the A339 as preparation begins for the lane widening.

The new kerb line for the A339 has been set out and started to be laid north of the new link road junction. This also included laying more 100mm diameter ducting which will also house the street lighting electricity supply, when the lamp columns are re-erected in their new location.

This week on site, more kerbing and binder laying was completed at various locations on the site.

This included the junction for the new link road, which will form the central island at the junction. The base course was extended from the link road to surround the new junction head and island.

Additionally, kerbing was completed for an alteration of the island outside of the West Berkshire recycling centre, which needed its width reduced to accommodate the road widening of the A339 at later stages.

This week on site, the setting out engineer returned to set out the kerbing and levels of the new junction for the link road. This involves using a total station to translate the design in to a physical location on site.

Once the locations have been determined, the points are staked out and strung together to create an accurate line to lay the kerbs to.

This week on site, the next layer of the link road was laid which is referred to as the binder layer. This provides a solid surface to lay the surface course.

In addition to the binder layer on the carriageway, the footpath was also laid up to binder level. Before this could happen the edgings at the rear of the footpath were also set in their concrete bed and backing.

Other activities completed this week included laying more ducting for the street lighting parallel to the A339, in preparation for when the link road is connected. The area in the below picture will become the new junction for the link road.
