Removing the roundabout and returning the traffic to two-way will let us improve pedestrian crossings and add segregated cycle lanes. A new public space to be built around a new station entrance will make it easier to walk into and around the station and change between trains and buses

Switching traffic to two-way

Old Street roundabout is now running with two-way traffic.

The southeastern arm of the roundabout is temporarily closed to vehicles. The right turn from Old Street west in City Road south is permanently banned.

Take extra care when walking, cycling and driving in the area - traffic may be coming from a different direction than you're used to.

Final road layout

Although traffic will flow in two directions after this switchover, the final road layout at Old Street will only be in place when we close off the northwestern arm of the roundabout later in 2019. We'll update this page with details closer to the time.

What we're doing

As part of the scheme we will:

  • Remove the existing roundabout and close the northwest arm to create a new public space
  • Switch road traffic movements to two-way
  • Remodel the entrances to the Tube station by closing three of the four existing subway entrances and building a new main entrance which will be accessible from the new public space and from Cowper Street - this will replace existing subway entrances
  • Improve facilities for pedestrians and cyclists travelling through the junction with segregated cycle lanes and signal-controlled pedestrian crossings
  • Build a lift connecting the public space to the subway retail concourse, replacing the subway ramps

The works

Phase A - enabling works and site investigations

We have:

  • Completed trial hole investigations on the pedestrianised area of Cowper Street
  • Closed the end of Cowper Street nearest to the roundabout for pedestrians until November 2019. This lets us finish these works and build the new Cowper Street station entrance. Diversion signs show how to get into Cowper Street

Phase B - advanced highway works

We have:

  • Removed the traffic islands on all four arms of the roundabout to make sure traffic flows safely during Phase C
  • Closed the southeastern pedestrian subway (Subway 2) leading to St Agnes Well and the Tube

Phase C - main works

Since May 2019 we have:

  • Closed the southeastern arm of the roundabout to traffic. Two-way traffic is now running around the junction
  • Created dedicated cycle and pedestrian routes through the works site

Other works in this phase include:

  • Diversion of a 24-inch Thames Water main‎
  • Building the new entrance at Cowper Street and subway works
  • Installation of a temporary service lift
  • Structural works to prepare for construction of new main entrance

Phase D - main works

November 2019 - October 2020

Main works will include:

  • Closing the northwestern arm of the roundabout to traffic
  • Building a new main station entrance
  • Building a new lift into St Agnes Well mall
  • Transforming the roundabout into a new public space
  • Permanently closing Subways 1 and 3

These works will be done Monday-Saturday, 07:00-19:00 with some night works between 20:30-05:30 because of Tube operations.

Public drop-in sessions

We hold weekly public drop-in sessions to share more about the Old Street roundabout improvement works.


  • Every Monday, 11:00-13:00
  • Every Tuesday, 11:00-13:00
  • Second and fourth Wednesday of every month, 16:00-18:00

These sessions are run in collaboration with Islington Council.

For general information about the project:



A public consultation on the proposals for Old Street was held between November 2014 and January 2015.

More than 1,300 comments were received. The headline results:

  • 87% of respondents believed that the proposals would improve conditions for pedestrians and cyclists
  • 63% believed that bus and tube passengers would also benefit
