Changes to the road layout at Lambeth Bridge north

The existing roundabout would be removed and replaced with crossroad junction, controlled by traffic signals on all four arms. This would include innovative cycling facilities and the introduction of a ‘bus and cycle only’ slip road from Millbank north, onto Lambeth Bridge.

Changes to the movement of traffic through Lambeth Bridge north

To facilitate the removal of conflicts between vehicles and cyclists, changes to the way general traffic is able to move through the junction would be required.

For general traffic we propose to introduce:

  • ‘Straight-ahead only’ for traffic exiting Millbank north
  • A time-of-day banned right-turn from Millbank south onto Lambeth Bridge during the evening peak
  • A banned left-turn for northbound traffic from Millbank south into Horseferry Road
  • ‘Straight-ahead only’ for traffic exiting Horseferry Road

Subject to the outcome of consultation, the security sensitivities in the area including access to Thorney Street would also be reviewed at the next stage of the project.

Design features at Lambeth Bridge north

Our proposals contain the following design features, as shown in the following computer generated artist’s impression (CGI):

Improvements for cyclists

  • Changes to the road layout would remove left-turn conflicts with vehicles
  • Continuous left-turn cycle bypasses on three junction arms, and a ‘bus and cycle only’ slip road from Millbank north to Lambeth Bridge would allow cyclists to bypass the junction when turning left. This would remove the left-turn conflict with general traffic
  • Cycle bypasses would improve connectivity, creating easy access to Cycle Superhighway Route 8 (CS8) from Millbank south to Wandsworth
  • CS8 would also be extended so it meets the junction at Millbank south
  • Two-stage right-turn facilities for cyclist movements
  • Cyclists approaching Millbank from Lambeth Bridge would be separated in time and space from general traffic. This is by the new cycle track provision on the bridge and separate cycle-signals at the junction.
  • Where possible the junction gradient would be reprofiled to increase the level of comfort for cyclists. The structure of Lambeth Bridge limits the extent to which the gradient from the bridge to the junction can be reduced.

Improvement for pedestrians

  • Existing pedestrian crossings would be converted from zebra to straight across signalised crossings with countdown technology that displays how many seconds there are to cross the road
  • New traffic signals and turning restrictions would maximise the time pedestrians receive to cross the road
  • Changes to the road layout would allow a reallocation of space from the carriageway to the footway which would increase space given to pedestrians
  • The surface area of the public realm would increase by approximately 1,370 square metres
  • The reduced carriageway footprint would also bring the opportunity for more greenery and other urban realm improvements, subject to local security restrictions
  • Where possible footways will be reprofiled to increase the level of comfort for pedestrians, however the structure of the bridge limits the extent to which the gradient from the bridge to the junction can be reduced

 

The palm tree on the northern side of Lambeth Bridge

The proposal to convert the northern roundabout to a signalised crossroad junction would require the removal of the roundabout and the iconic Phoenix Palm tree in its centre. Subject to the outcome of this consultation, the tree would be removed and we would look to replant it locally.  We would work with our tree experts, Westminster City Council and Lambeth Council to identify a suitable place for this.
