New proposals for a busy junction in Brentford would see a ban on right turns from the A4 eastbound into Windmill Road.

Transport for London (TfL) are currently holding a consultation on the proposals which also include:  

  • Creating shared areas for pedestrians and cyclists around the crossing points.
  • Adjusting the kerb lines and installing a new traffic island to encourage correct lane use.
  • Install two additional traffic signals to help increase driver awareness of the A4 crossings.
  • Improving the lighting at the two A4 crossing points (under the M4) to enhance the environment for pedestrians and cyclists.

While completing these works, TfL would also take the opportunity to upgrade the junction’s existing signal equipment

For the new toucan crossing to be installed, the right turn from the A4 eastbound into Windmill Road would have to be banned. 

TfL also expect the proposed ban to increase safety at the junction by reducing the number of potential collisions involving right turning vehicles.  

The right turn ban would mean that vehicles could use either Boston Manor or Ealing Road to access the south side of Windmill Road.

On average, 16 vehicles per hour currently turn right at the junction.
