Oxford Circus Diagonal Crossing

Construction of Europe’s busiest diagonal crossing in London’s West End

Project outline 

Construction of a new diagonal crossing at Oxford Circus and improvement works to Oxford Street to reduce traffic flow and increase public transport and pedestrian access.

Key challenges

Oxford Circus is one of the world’s busiest intersections, used by 200 million shoppers and workers annually.  All works needed to be managed to enable the Mayor to open phase one of the scheme before the Christmas Embargo (November 2009).

Project delivery and innovation

The work was carried out over two phases, introducing the innovative diagonal pedestrian crossing and improving the streetscape around Oxford Circus.  Key elements included:

  • Stakeholder management, including coordination of communications for the Crown Estate, Transport for London, and the Regent Street Association.
  • Concrete and metal barriers around the tube station entrances/exits were removed.
  • High quality natural stone finishes were used – some of this was reused to achieve cost savings.  
  • Lighting and signage were enhanced.

Key facts

  • Pavement capacity has been significantly increased and the new diagonal layout offers a more efficient crossing.  Pedestrians can now cross the intersection in an ‘X’ as well as straight ahead, doubling its capacity.
  • At peak times 2,000 vehicles and 100,000 pedestrians per hour use Oxford Circus, this flow had to be managed throughout the project.
