Bromley (Parliament Politics Magazine) – Parts of the M25 in Bromley will face 10 days of delays as maintenance work begins on the Shoreham bridge, with drivers advised to plan ahead.
The M25 will be closed at night between Junction 5 and Junction 4 from Wednesday, October 8 to Friday, October 17.
The A21 northbound from Junction 5 and the junction between Junction 5 (Chevening Interchange) and Junction 4 (Orpington and Bromley) will be closed for the next six days.
Weeknight closures from 10 p.m. to 5:30 a.m. (11 p.m. to 6 a.m. on Fridays) will occur as part of necessary repairs to the bridge that spans Shacklands Road in Shoreham, which includes replacing an expansion joint.
Drivers are informed that while the M25 clockwise lane will stay open, those going the other way would have to take a detour.
Travel east on the M26 from Junction 5 to Junction 2a (Wrotham Heath Interchange).
Proceed north on the A20 London Road, then turn right onto the M20 at Junction 2, then turn right back onto the M25 at Junction 3.
Additionally, vehicles traveling north on the A21 will be rerouted via the M25 in a clockwise direction until Junction 6 (Godstone Interchange), after which they will take an anticlockwise detour.
According to National Highways, closures won’t happen on weekends unless emergency work is needed between Saturday, October 18, and Wednesday, October 22, overnight.
It is recommended that drivers make advance plans, monitor real-time travel information, and factor in additional travel time.
Drivers in the Croydon, Godstone, and Bromley areas of south-east London may see more traffic as a result of vehicles being rerouted.
How will local bus and freight routes be affected?
Buses that would typically use the affected anticlockwise M25 roadway between junctions 5 and 4, or the A21 from junction 5 heading northbound, will reroute via the M26, A20 and M20 to get around the closured route.
This may create longer journey times and changed timetables for services affected in part due to congestion and re-routing. Where routes bookend the diversions, temporary changes to bus timetables or pickup/drop-off points may be put in place.
Freight will also be directed through diversion routes and could cost drivers miles and time on deliveries.
