Work will take place on the bridge at junction 15 where the carriageway crosses over the M4. It involves the replacement of the expansion joints which allow structures to expand and contract with changes in temperature. All the work will be carried out overnight, with minimal impact on road users.
Stephen Hall, Highways Agency Asset Manager said:
This is the start of a scheme to replace a number of bridge joints on the M25 between junctions 12 and 15, ensuring that the thousands of drivers who use the motorway between these junctions every day can continue to make safe journeys.
We’ve planned the work to minimise disruption. We will be carrying out the work overnight, when traffic flow is at its lowest.
Work is scheduled to begin on Monday 12 January with the project on junction 15 to be completed by Wednesday 21 January. The clockwise carriageway will be closed at junction 15 overnight, between 10pm and 5.30am (Monday – Thursday) and 11pm and 6am (Friday) for five nights from Monday 12 January. The anticlockwise carriageway will be closed overnight, between 10pm and 5.30am for three nights from Monday 19 January. Road users will be diverted via the M4 junction 5.
Details of further bridge joint replacements between junctions 12 and 15 will be announced shortly.
