Highways England: M4 J19-20 Winterbourne Lane underbridge

Skanska Infrastructure Services - 23rd June 2015

I am writing to advise you that Skanska, working on behalf of Highways England, will be carrying out vital bridge repair works in your area next month.

The work on the Winterbourne Lane underbridge, which carries the M4 motorway over the B4057/Beacon Lane, consists of concrete repairs and waterproofing. This essential work is required to maintain the integrity of the structure and to avoid more costly repairs in the future.

The work is scheduled to start on the 20 July and will last for approximately 6 weeks. We’ve chosen to carry out the work during the summer holidays as this will cause less disruption than doing the work during term time. Additional work on the M4 will take place using narrow lanes in September, lasting approximately 4 weeks but this will not impact users of the B4057. This work is going to address the root cause of the water leakage by removing the existing central reservation on the M4, a solid concrete slab will then be cast to prevent water flowing down to the underside of the bridge.

The type of work taking place means we need to close the road to through traffic for the entire duration of the scheme. The closure is to ensure the safety of both the public and our workforce. However, access will remain open to pedestrians and cyclists.

During the work, a clearly signed diversion will be in place and details of the diversion can be found in the map overleaf. Access will be maintained for residents and emergency services.

We will of course make every effort to ensure that the impact of our roadworks on the local community is kept to a minimum. We understand our works may cause some inconvenience and disruption to you, along with other residents and drivers and we would like to apologise in advance and kindly ask for your patience whilst the works are taking place.

Please get in touch if you have any queries or comments about the works at the Highways England Information Line on 0300 123 5000.

Yours sincerely,

Sam Landrigan
