Brook Street Interchange

Brook Street Interchange is junction 28 of the M25 and junction 11 of the A12.

It was first built when Brentwood was bypassed in 1966, predating the M25, and the old A12 through Brentwood was re-numbered as the A1023.

The M25 viaduct was built over the top in 1981, finally opening in 1983 and linking the A12 to the motorway network. This junction has been remodelled in recent times to signalise it and increase stacking space to cope with the large traffic flows using it, however delays peristed at the junction, so in November 2016, Highways England opened consultation on proposals for further improvements to the interchange.

It also serves as a crossing of the River Ingrebourne.
