Swanley J3 roundabout closures coming up in Nov, Dec and Jan…
Earlier today Swanley Town Council met with Connect Plus to discuss Junction 3. Connect Plus work on behalf of National Highways to manage and operate the M25 network.
It was explained to the Town Council that works will soon take place on the roundabout to replace the traffic light system. Something the Town Council had previously reported as being an issue. This needs to take place as the current system no longer can be repaired due to parts no longer being made for the lights. This is also why some traffic lights have remained non-operational on the roundabout for an extended period.
Works will consist of:
- Excavations for the installation of new traffic signal assets
- The removal of existing traffic signal equipment
- The removal and replacement of the existing cable
- Slot cutting
All works leading to new traffic signals being in place.
Connect Plus will be implementing a mixture of traffic management at the roundabout including 24-hour lane closure, and full overnight roundabout closures.
A static lane closure will be implemented on the inner circulatory carriageway between 2 November and 18 December 2026. This accommodates for a temporary pedestrian walkway to maintain local access and operation of all traffic signal stages and approaches.
Then between January 2027 and March 2027, overnight closures will be in place regularly between 10pm and 6am. They will be localised to a quarter of the roundabout at a time to reduce disruption.
Diversions for motorway traffic will be in place via M25, M20, A20.
For non-motorway traffic, a diversion will be in place via Wested Lane, Crockenhill Lane and Sparepenny Lane.
Swanley Town Council requested that the works are suitably coordinated to minimise disruption for residents with Kent County Council and the contractors appointed to build the new LIDL roundabout.
The Town Council also pushed for regular litter picks to take place during the works and discussed establishing new preventive measures to reduce littering on the roundabout.
Official National Highways literature with more details will be posted in the coming days regarding these works.
