Maintenance work to replace the beams and waterproofing material to the bridges which carry the M4 over the B4009 Hampstead Norreys Road near Hermitage, Brocks Lane near Frilsham and Burnt Hill Road has now started.
As previously advised, during work to demolish and install the bridge deck beams, specialist working methods and equipment will be required which will include larger cranes that will sit across all lanes of the motorway.
To allow this work to take place we will be fully closing the M4 east and westbound carriageways between junctions 12 and 13 over the following entire weekend periods (9pm Friday through to 5am Monday):
- Friday 24 to Monday 27 November 2017
- Friday 8 to Monday 11 December 2017
- Friday 15 to Monday 18 December 2017
- Friday 19 to Monday 22 January 2018 (contingency)
During the closures a clearly signed diversion will be in place via the A4 (through Newbury, Thatcham and Woolhampton), however as we are expecting this route to be extremely busy alternatives routes will be suggested further afield.
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.
We would like to apologise in advance for any disruption caused by these closures; if you have any questions, or if you’d like you know about our work please contact us on 0300 123 5000 or email email@example.com. Or you can visit our website at www.highways.gov.uk/roads
