Improvements to M25 junction linked to A12 have been given the go-ahead

A proposed multi-million pound upgrade to a busy M25 junction linked to the A12 has been given the go-ahead.

Junction 28 of the M25, commonly known as the Brook Street roundabout, will now be reconfigured to improve traffic flow, while a new two-lane loop road will be created for traffic leaving the M25 to join the A12.

A short section of the M25 will be widened with the eastbound A12 interchange at the junction in a bid to reduce congestion.The scheme has been set out to improve journey times at the often-congested roundabout, as well as minimise the number of accidents and disruption and improve air quality.

Highways England says that it is likely there will be queuing traffic back onto the M25 due to the improvements, which will cost in the region of up to £100m.


More than 90 per cent of people who took part in the consultation period for the scheme agreed that improvements were needed at the junction.

Piotr Grabowiecki, Highways England Project Manager, said: It’s great to see that there is clear backing for the improvements, and I would like to thank everyone who took part in our consultation.

“We can now move on to developing a detailed design for the upgrade. There will be another opportunity for anyone interested in the scheme to have their say early next year, when we put the plans to people for their views.”
