We're working closely with Islington and Hackney Councils to make Old Street roundabout more pedestrian- and cycle-friendly. Preparatory works are underway - main works will begin in spring 2019.
The roundabout is being removed and traffic returned to two-way - this will let us put in segregated cycle lanes. A new public space will be built around a new station entrance.
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 building a new main entrance which will be accessible from the new public space and from Cowper Street and will replace existing subway entrances
- Close three of the four existing subway entrances, replacing them with new surface-level, signal-controlled pedestrian crossings
- Improve facilities for cyclists travelling through the junction with segregated cycle lanes and separate traffic signals
- Build a lift connecting the public space to the subway retail concourse, replacing the subway ramps
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 March 2019 - Site investigation works will include:
- 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
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 late 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-Sunday, 20:30-05:30 to minimise the impact on traffic during the day. Our contractor will try to keep noise levels to a minimum
- 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
Phase C - main works
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
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
