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.

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
  • Re-model 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

Site investigations

We have started some preparatory work to make sure that the main transformation can start on time. Our initial investigations include:

  • Recording in detail the condition of St. Agnes Well subway retail concourse
  • Excavating to confirm the location and depth of utilities in the area
  • Digging holes in the footway to confirm where we might plant trees and provide street furniture in the future

The impact on traffic will be kept to a minimum but minor diversions for pedestrians are needed.

The works - What's happening and when

Phase A - enabling works and site investigations

Until late April 2019

  • Trial hole investigations on the pedestrianised area of Cowper Street - weekdays 08:00-17:00 - will make it possible for Thames Water, Cadent Gas and UKPN to divert utilities at Cowper Street/Old Street roundabout and a new stepped entrance to be built
  • From 18 March until November 2019 we will need to close off the end of Cowper Street nearest to the roundabout for pedestrians. This will let us finish these works and build the new Cowper Street station entrance. Diversion signs will 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

From 20 March 2019 to 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:

  • Closure of 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 dedicated cycle and pedestrian routes through the works site
  • Diversion of a 24-inch Thames Water main‎ 
  • Construction of 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
