A30 Crooked Billet, Staines scheme update

Highways England have informed Surrey County Council funding has now been identified to undertake a substantial improvement of the Crooked Billet junction, which would complement the Wider Staines STP by providing high quality pedestrian and cycle crossing facilities at this junction.

Highways England are planning to start construction of this scheme in April 2020, finishing March 2021.

Why we need this scheme – The A30 Crooked Billet roundabout is currently an unbalanced roundabout where the number of lanes varies as you travel through the roundabout leading to unnecessary weaving and safety issues.

Proposed improvements:

  • Realign the eastbound and westbound carriageway markings through the centre of the roundabout on the A30 London Road to remove unnecessary lane changing
  • Widening of the A30 eastbound exit lanes approaching the roundabout to increase usage of both lanes, providing improved road capacity and traffic flow
  • Remove the existing substandard subway and footbridge and replace them with the new pedestrian and cycle routes across the roundabout. This will link into the new pedestrian/cycle routes to be implemented by Surrey County Council towards Staines and Heathrow.
  • Upgrade and synchronise the existing traffic signals to improve traffic flow

Proposal benefits

  • Improved safety with reduced accident rates based on revised road markings and road widening
  • Improved routes for pedestrians and cyclists linked with proposed Surrey County Council’s scheme which are to be implemented at the same time as this scheme
  • Removal of sub-standard subway that has flooding and maintenance issues
  • Provide more reliable journey times through the use of synchronised traffic signals
