The council is advising the public that the Station Road railway bridge in Langley will be closed in both directions for approximately six weeks.
This is because drainage remedial works and highway improvements are set to take place from the end of this month.
Diversion routes will be set up in both directions from Monday 30 July, while work is carried out day and night to correct ongoing flooding issues, improve cycle and pedestrian access, modify the crossroad and refurbish traffic lights.
The official diversion route will be via the A412 Uxbridge Road, accessed via Langley Road and Wood Lane.
The reason behind this route is because it will accommodate all traffic; and alternative diversion options would not have been able to.
Pedestrian access will be maintained under the bridge.
Once this extensive work is completed, it will mean there will be improved access to Langley Station, the installation of a cyclist and pedestrian crossing, an upgraded cycle route, crossroad and traffic lights; and the drainage system will be fixed to prevent future flooding.
The improvement works are being carried out as funding from the Berkshire Local Enterprise Fund was won to improve access to Langley Station.
The council’s transport and highways team is taking this opportunity to address all required works for the road at the same time.
The team also opted for closing the bridge during the summer holidays to cause as minimal disruption as possible.
Councillor Martin Carter, cabinet member for planning and transport, said: “We apologise in advance for any inconvenience caused by this closure.
“However, we have received multiple complaints about the flooding in Station Road and though the sun is shining now, the issue will return if we don’t rectify it, when it inevitably starts to rain again.
“We appreciate the closure is not ideal for road users, but opted to undertake the work during this quieter school holiday period to try to cause as little disruption as possible.
“While it will be a short term pain during the closure and diversion period, it will be a long term gain for the area, following the completion of the improvements.”
