A3 Huguenot Bridge

We have completed refurbishment work to the 35 year old bridge to prolong its life and ensure no major maintenance will be required for many years. The refurbishment involved the construction of new run-on slabs, installation of a new waterproofing system, replacing the expansion joints and resurfacing the deck. Works were also carried out underneath the structure along the A214 Trinity Road to carry out repairs to the concrete abutments, refurbish the bearings and install new pigeon netting.

A406 Southend Road

The A406 Southend Road (North Circular Road) at South Woodford, has been the subject of a Transport for London TLRN carriageway renewal scheme, that successfully completed in November 2014.

The works involved the removal of old road surface material, repair of the underlying concrete road base construction, and installation of a bespoke new wearing course material. Innovative processes were used to repair concrete slabs using technology recently used on the M25.

The scheme resulted in 38,637m2 eastbound and 35,941m2 westbound of renewed carriageway, which at 74,578 is the greatest combined total area of resurfacing of a single works site in our history.

Chiswick Bridge refurbishment

Work to strengthen and refurbish the 82-year-old Grade II listed Chiswick bridge is now complete; restoring its heritage features and extending its life for many years to come. Refurbishment works started on the 185m long Chiswick Bridge in April 2014 and ended in June 2015.

We conserved much of the bridge's original stonework in its original position, or sourced replacements when required from the same quarry that supplied the Portland stone in the 1930s. A new segregated walkway and cycleway has also been installed, and new heritage lighting has been placed across the bridge deck and staircases to help maintain its classic 1930s style. The project also helped out the Tideway Scullers School rowing club, which stores its equipment under the bridge, by re-building racking for their boats, constructing a concrete ramp for the boats and installing new fencing and gates.

Colliers Wood

We worked with the London Borough of Merton, the Mayor of London and a developer to successfully upgrade the carriageway and footways around Colliers Wood, improving pedestrian links and cycling infrastructure. This has also improved the urban realm between Colliers Wood Tube station and The Tower, including the northern section of Christchurch Road.

Cycle Superhighway 1

We have completed works on Cycle Superhighway 1 (CS1) from White Hart Lane to Liverpool Street Station. CS1 aims to provide safe and convenient journeys along its 11km north-south route, improving conditions for cyclists and reducing conflict between motor vehicles and cyclists. For much of its length, CS1 runs along residential streets, away from the majority of car, freight and bus traffic.

Cycle Superhighway 2 upgrade

We have improved Cycle Superhighway Route 2 (CS2) between Aldgate and Bow Roundabout by introducing segregated cycle tracks. Through upgrading 11 major junctions with innovative cycle facilities we have given more time and space to cyclists.

The link between the upgraded section of CS2 and the already segregated extension of CS2 between Bow and Stratford was completed as part of the Bow Vision interim scheme.

Cycle Superhighway 5

We have completed works on Cycle Superhighway 5 (CS5), creating a two-way segregated cycle track from Oval to Pimlico. CS5 has transformed Vauxhall Gyratory, removing a previously hostile environment that posed a significant barrier to cyclists in the Vauxhall area. CS5 provides a connection to Cycle Superhighway 7 at Oval (via Kennington Oval) and intersects with Cycle Superhighway 8 at Millbank.

Cycle Superhighway 8

Cycle Superhighway 8 (CS8) runs between Wandsworth and Westminster. We completed cycle safety improvements on Chelsea Bridge at the junction with Grosvenor Road in 2016.

Elephant and Castle

We have changed the northern roundabout at Elephant & Castle to provide two-way traffic, dedicated cycle lanes and pedestrian crossings at surface level. We introduced a new two-way traffic system by closing in the south-eastern arm of the roundabout.

The former subway network has been replaced with seven new direct street-level pedestrian crossings, and we have provided segregated cycle lanes to support the growing number of people cycling through the area.

We have planted 32 new trees and nearly 1000 new shrubs across the junction, alongside 880m2 of lawns and an impressive 7,000 plant, 120m2 green wall on the Bakerloo line station. We've also installed 50 new benches and new street furniture across the junction, along with the creation of a new accessible public space.

Euston Circus

We have worked with Camden Council to radically transform the junction at Euston Circus. The new design has resulted in:

  • A simplified traffic layout and improved access to nearby Tube stations and University College London Hospital (UCLH)
  • Enhanced contraflow cycle lane along Euston Road providing simpler and safer journey options for cyclists
  • A new public space which provides a more welcoming environment with wider pavements, new trees and additional landscaping improvements throughout the area

Fore Street Tunnel

Work to upgrade the Fore Street Tunnel in north London was completed in September 2015. The refurbishment, which included minimising the damage caused by groundwater leakage and replacing the existing lighting with LEDs, has helped to lower energy consumption and keep the tunnel safe and fully functional for the 60,000 vehicles that travel through it every day.

Hammersmith flyover

We are well on the way to finishing a major programme of works to strengthen Hammersmith flyover. By summer 2015 the entire flyover was waterproofed and resurfaced, the bearings replaced and a new carriageway drainage system installed.

Hogarth flyover

We have also completed work to strengthen and repair Hogarth flyover to prolong its life and ensure no major maintenance will be required for many years. The refurbishment involved replacing the deck, replacing and upgrading the parapets, repairing the steelwork, and improving the lighting on the slip road where the A316 merges with the A4.

Holborn Circus

Holborn Circus junction has also been transformed with a new layout, making it safer for pedestrians and cyclists. As part of the works, the Grade II-listed bronze statue of Prince Albert has been restored by conservation experts and relocated to the west.

Lane rental scheme

The introduction of our lane rental scheme in 2012 means that all roadworks are now co-ordinated with other utility companies on our busiest roads during peak times. This helps to reduce the length of time in which work is carried out and minimises disruption. As part of this scheme, we co-ordinated roadworks on Borough High Street, reducing the time needed for the work by six months. You can find out more about all the work we're doing in Improvements & projects.

Malden Rushett

We have improved the busy junction at Malden Rushett in the Royal Borough of Kingston upon Thames to reduce road collisions and make the area safer for pedestrians.

The work, which began in September 2014, has improved road safety and will reduce congestion at the junction of the A243 Leatherhead Road, B280 Fairoak Lane and Rushett Lane. Right turn traffic signals and wider roads at Fairoak Lane and Rushett Lane have been installed, as well as direct crossings for pedestrians and advance stop lines for cyclists. After a period of monitoring, our new traffic signals will operate under SCOOT technology which will bring a substantive change to current traffic conditions. SCOOT technology allows signal timings to adapt and respond to traffic levels on a second-by-second basis so that light sequences can adapt and respond to live traffic situations quickly and effectively.

Drainage in the area has been improved, and the roads resurfaced to provide smoother, safer driving conditions. We have also fitted new street lights and signs and are carrying out landscaping which includes seasonal hedgerow planting and replacement fencing.

Oval Triangle

As part of the redevelopment of four junctions around Oval station to create segregated cycle lanes, enhance public spaces and improve pedestrian crossings, works at the A23 Kennington Road Junction and A3 Kennington Park Road have now been completed.

A23 Kennington Road junction improvements

A banned turn from Kennington Road into Kennington Park Road has been implemented to reduce the time and the number of separate road segments it took for pedestrians to cross over Kennington Road. It has also increased footway space at the corner of this junction. 

A hold on the left turning traffic has reduced the potential for conflict between those motorists and ahead cyclists. Cyclists at this junction now receive a green light to proceed ahead at the same time as ahead motor traffic. Ahead cyclists and traffic will then be held to allow for left turning cyclists and vehicles. This new design feature will reduce the collisions at the junctions.

A3 Kennington Park Road improvements

New segregated/stepped cycle tracks have now been opened on the Cycle Superhighway 7 alignment in both directions along Kennington Park Road. The tracks join the improvements previously delivered at the junction with Kennington Road.

Cyclists now benefit from a second 'hold-the-left' junction at Brixton Road, where left turning traffic is separately signalled from cyclists wishing to continue south on Kennington Park Road.

Pedestrian countdowns

We have been installing pedestrian countdowns at traffic signals to tell pedestrians how long they have to cross the road safely. More than 900 pedestrian countdown sites have been installed as of December 2016.


To make Stockwell safer for cyclists we have built a new cycle route and reconstructed the junction next to the Stockwell Memorial Garden, removing the gyratory. We have also created a new public space at the garden making it more accessible to residents and visitors.

Southall Broadway

The westbound closure of Southall Broadway between July and December 2014 allowed Ealing Council to carry out improvement works. The works are part of the council's Southall Big Plan, which is changing the street layout to improve safety, widen the footways and help smooth the flow of traffic.

Thurlow Park bridge

We have worked with Network Rail, Lambeth Borough Council and local residents to install a detector system to spot vehicles that are too high to pass through the bridge at Tulse Hill.

The Overheight Vehicle Detection (OVD) system uses sensors to spot vehicles that are too high to pass under the bridge and sets off a series of warning signs. There are now six sets of electric warning signs triggered by the OVD around the bridge, along with a signposted alternative route.

Tottenham Hale

The huge roundabout - or gyratory - at Tottenham Hale is just one example of the work we've been doing. Work to convert the roundabout from a one-way to a two-way system is now complete. This has resulted in improved road safety, improved cycle routes and cycle parking, more pedestrian crossing points, improved street lighting and a better bus station.

Woodlands Retaining Wall

Work to replace and strengthen the woodlands retaining wall along the A406 North Circular Road near Golders Green has been completed. This new permanent wall, which replaces the original 1920s structure, protects the land and trees behind it from falling onto the road, making it safe for pedestrians and other road users. The structure features an additional 'green wall', which provides a home for more than 10 plant species and also improves local air quality.
