The roundabout is being removed and traffic returned to two-way - this 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

We plan to switch the roundabout to two-way traffic over the Whitsun Bank Holiday weekend (Friday 24-Monday 27 May 2019).

  • Work will start from 21:30 on Friday 24 May and continue until 00:01 on Monday morning 27 May 2019. City Road south and Old Street west will be closed during this time. The footway on the southeastern arm will also be closed for pedestrians
  • From 00:01 on Monday 27 May two-way traffic will be introduced at Old Street and the southeastern arm of the roundabout will be closed to vehicles

Final road layout

Although traffic will flow in two directions after this stage of works, 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

Drivers should expect minor delays while travelling through the area. Please plan ahead, allow more time for your journey, and travel outside of peak periods if possible. Check before you travel at tfl.gov.uk/trafficnews and follow @TfLTrafficNews on Twitter.

Phase B - advanced highway works

Until late May 2019:

  • Works include removing the traffic islands on all four arms of the existing roundabout to make sure traffic flows safely when the main works start in Phase C
  • These works will be carried out at night, Monday-Saturday, 20:30-05:30 to minimise the impact on traffic during the day. Our contractor will try to keep noise levels to a minimum. The noisiest activities will be done in the earliest parts of the shift and no noisy work will take place after midnight
  • No road or subway closures will be needed for the advanced works. Bus stops may be relocated temporarily. We will display notices on bus stops ahead of any changes
  • No road closures, subway closures or bus stop relocations will be needed for these works. Three bus stops will be moved permanently before the main work, not far from where they are now. We will display notices on bus stops ahead of any changes.

Phase C - main works

May 2019

Main works will start in 2019, including:

  • Closing the southeastern arm of the roundabout to traffic on 24 May 2019. Two-way traffic will be able to flow around the junction. 
  • Creation of a dedicated cycle and pedestrian routes through the works site
  • 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.

When: Every Wednesday, 16:00-18:00 

Where: At the retail unit opposite the Old Street Tube station ticket hall, in the subway area (this is known as St Agnes Well)

These sessions are run in collaboration with Islington Council.
