Forty Lane/Blackbird Hill Proposed Road Safety Improvements

Closed 20 Mar 2020

Opened 13 Feb 2020


Each year the Council identifies locations in Brent with the highest number of Personal Injury Accidents (PIAs) and considers road safety measures to help reduce the number of collisions. Over the last three years, there have been 22 collisions at and around both of the roundabouts with Forty Lane, Blackbird Hill and Salmon Street, Tudor Gardens. As a result, there have been 26 slight personal injuries.  This includes injuries to 14 drivers, 4 passengers, 3 motorcyclists, 4 pedal cyclists and 1 pedestrian. There were no fatalities or serious injuries.

We are therefore proposing to introduce measures around these roundabouts to improve safety and accessibility for all road users.

Why We Are Consulting

The proposed improvements are shown in the plan and are outlined below;  

  • Proposal to reconfigure the existing traffic island in Forty Lane and upgrade the existing dual pelican crossing to improve pedestrian safety. 
  • Proposal to install new splitter island to protect the slip lane from right turning traffic into Forty Lane.
  • Proposal to reduce the dual-lane entry into one-lane at roundabout entering from Blackbird Hill to regulate vehicle movements, reduce congestion and improve safety and access to Tudor Gardens.
  • Proposal to enlarge the existing splitter island in Blackbird Hill to improve lane discipline.
  • Proposal to enlarge the mini-roundabout at Blackbird Hill and Forty Lane to regulate vehicle movements.
  • Proposal to provide a raised mini-roundabout and widen the existing splitter islands in Tudor Gardens and Salmon Street. This will help slow vehicle speeds on the approaches.
  • Proposal to widen the pedestrian crossing facilities in Tudor Gardens and Salmon Street in order to improve pedestrian comfort and safety.
  • Removal of the existing barriers and bollards and other redundant street furniture to declutter and improve the streetscape.
