| Action: | M25/A12 Brook Street Interchange - Improve Northbound A12 On-slip | ||
| Priority: | High | Ref: | 3A |
| Initiation: | The Brook Street Interchange northboundon-slip road is subject to congestion due to the lack of capacity on theA12. This causes joining traffic to queue on the slip road and back tothe roundabout and from the roundabout onto the M25 main carriageway.Traffic joining the A12 does not follow the road layout as currentlymarked with many vehicles crossing the hatched markings. | ||
| Action description: | It is intended to widen the northbound A12on-slip to provide a ghost island with a dedicated lane for A12 traffic onthe inside slip lane and a merge facility for the outside slip lane. | ||
| Objective(s) met: | The principal gains will be for economyobjectives, namely OC2 and 3, but gains will also be made in safety, ie OS2and 3. With the reduction of queuing cars environmental benefits may begained for OE5. | ||
| Benefits: | By assisting the slip road traffic to join themain A12, congestion on the roundabout will be reduced as well as the backingup of traffic onto the mainline M25. This will also reduce accidents at thislocation. | ||
| Timescale: | Statutory procedures will be carried out in thefirst two years with implementation in the third year of the programme. | ||
