St John's Road to Spring Grove

Improve pedestrian crossings outside Sainsbury’s Local (489 London Road) by introducing signal-controlled crossings, removing the existing traffic island and enlarging the pedestrian island to provide more space for people waiting to cross
Extend the eastbound ahead and right-turn lanes between The Grove and St John's Road to improve traffic flow. An Advanced Stop Line would also be provided at the St John's Road junction, helping cyclists position themselves more visibly at traffic signals
To accommodate the westbound cycle track, five parking spaces outside 490-495 London Road would be removed. Parking on the north side (outside of 484 London Road) would be increased from eight to ten spaces
Narrow the vehicle access points to the garage west of St John's Road, reducing the distance pedestrians need to cross
Introduce a bus stop bypass at bus stop L with a pedestrian crossing outside West Thames College to provide safe access to bus services
Introduce a bus stop bypass at bus stop G
Continue the cycle route beyond Sidmouth Avenue by introducing a segregated two-way cycle track on one side of London Road. A new signal-controlled crossing would enable cyclists to safely transition between the one-way cycle tracks in the previous section and the new two-way facility

Spring Grove to Honnor Gardens

Relocate bus stop K outside the parade of shops (532-572 London Road) and move the parking and loading bays here closer to the Spring Grove junction. This would also allow us to increase the number of parking spaces from 10 to 13 while retaining one loading bay. To accommodate the cycle track, 6 parking spaces outside Warren Motors on the south side of London Road would be removed
Install a new ‘parallel’ crossing west of Thornbury Road, providing a safer crossing for pedestrians and cyclists and improving access to Thornbury Park. A ‘parallel’ crossing combines a traditional pedestrian zebra crossing with an adjacent designated lane for cyclists
Introduce ‘side-road entry improvements’ at Meon Court and Thornbury Park to slow turning vehicles and improve safety for pedestrians and cyclists
Relocate bus stop H approximately 40 metres to the east and introduce a new bus stop bypass outside Golden Court (649 London Road)
Remove bus stop J near Star Road. Passengers who currently use this stop would instead be able to access the eastbound Bridge Road bus stop (175 metres west)
Provide a new ‘parallel’ crossing at Thornbury Road, allowing pedestrians and cyclists to cross safely and improving access to Thornbury Park. A ‘parallel’ crossing combines a traditional pedestrian zebra crossing with an adjacent designated lane for cyclists
Remove the ‘uncontrolled’ pedestrian crossing outside of Access Self Storage (592 London Road). An ‘uncontrolled’ crossing is one which does not include zebra crossing markings or traffic signals

Alderwick Drive to Kingsley Road (A315 High Street)

Continue the segregated two-way cycle track through this section. To accommodate the cycle track, bus stops along this section would be relocated slightly and the central reservation repositioned
Introduce ‘side-road entry improvements’ at Alderwick Drive, Dominion Court and North Drive to slow turning vehicles and improve safety for pedestrians and cyclists
Upgrade the crossing on London Road, west of North Drive (outside Sunrise Radio), to a parallel crossing, making it easier and safer for pedestrians and cyclists to cross. A ‘parallel’ crossing combines a traditional pedestrian zebra crossing with an adjacent crossing for cyclists
Introduce a bus stop bypass at Hounslow Bus Station stop G, together with an additional zebra crossing linking the bus stop to the new parallel crossing, creating a continuous and more accessible route for passengers, pedestrians and cyclists
Simplify the Kingsley Road junction by providing wider pedestrian crossings, additional footway space and a larger central pedestrian island, making it easier and safer for people to cross

Why?

We have been working closely with Hounslow Council to develop plans that will make it safer, easier and more accessible for people to walk, cycle and use bus services between Brentford and Hounslow town centres.

Our proposals, known as the ‘Syon Park to Hounslow town centre walking and cycling improvements’, would extend the existing Cycleway 9 route and create a continuous cycling connection between Brentford and Hounslow. The proposed extension would be approximately three kilometres long, and would include upgrades to 22 pedestrian crossings, alongside other improvements to support safer and more convenient journeys for everyone travelling through the area.

Busch Corner Junction illustrative visualisation of proposed scheme

In the summer 2024 we held a consultation on Brentford to Syon Park walking and cycling improvements (between Alexandra Road and Beech Avenue). The proposals we are now consulting on, cover the sections needed to complete the route from Syon Park to Hounslow town centre (between Beech Avenue and School Road/Laurence Road junction).

Similar improvements delivered along other sections of Cycleway 9 have already led to increases in cycling, with counts showing substantial growth in the number of people choosing to travel by bike. By extending the route, we aim to encourage even more people to make everyday journeys by cycle.

Safety is the main reason for the proposed improvements between Syon Park and Hounslow town centre. Data from the most recent three-year period (to late 2025) shows:

126 recorded road traffic collisions
37 collisions involving cyclists
25 collisions involving pedestrians
25 serious injury collisions

Our proposals are also in line with our Vision Zero strategy which aims to eradicate deaths and serious injuries from our roads. The proposals for this scheme have also been designed according to our Healthy Streets approach, which aims to make London a safer, healthier and greener place to live and travel.

How it may impact you

While the impact may vary for individuals, the proposals are expected to have a largely positive overall effect.

Improvements for walking

The proposals include a range of improvements to make walking safer, easier and more comfortable. These include upgraded crossing facilities, safety improvements to side roads and junctions, and more space for pedestrians at key locations.

Key measures include wider zebra crossings, upgraded signal-controlled crossings, new pedestrian crossing opportunities, and changes such as footway build-outs and raised tables designed to reduce crossing distances, improve visibility and slow turning vehicles. Wider footways, larger pedestrian islands and waiting areas are also proposed at several locations along the route.

Improvements for cycling

The proposals will extend Cycleway 9 between Brentford and Hounslow, providing a more continuous route for people cycling. We would therefore expect people who cycle to benefit from our proposals.

The scheme includes new segregated cycle facilities, improvements at key junctions and crossings, safer side-road treatments, and floating bus stops which avoid cyclists having to pull out around buses and enhanced links to local destinations and existing cycle routes. These changes are intended to reduce interactions with motor traffic and provide a safer and more consistent cycling experience along the corridor.

Cycling levels have grown over recent years, with a 43% increase in journey stages between 2019 and 2025 across London. Recent data suggests there is already strong demand for cycling in the area - cycling levels on the completed Chiswick section of Cycleway 9 increased by between 25% and 40% between 2019 and 2024.

Changes impacting bus passengers

The proposals include changes to some bus stops and surrounding streets to help maintain reliable bus services while introducing new walking and cycling facilities. Improvements would make it easier and safer for passengers to access bus stops, including upgraded crossing facilities and changes to some bus stop locations along the route.

The scheme also includes new bus stop bypasses, at several locations, allowing cycle routes to pass behind bus stops. Mini zebra crossings would be provided to help passengers access bus stops safely and conveniently, with the designs following Transport for London and the Department for Transport’s best practice guidance.

Traffic and journey times

Our traffic modelling assessed journey times across the full route in both directions during the morning and evening peak periods. Predicted changes vary by direction and time of day, with general traffic journey times increasing by up to approximately 2 minutes eastbound and up to 3 minutes westbound across the route during the morning peak period assessed. Bus journey times are forecast to vary by direction and time of day, with increases of up to 100 seconds westbound and up to 50 seconds eastbound across the route. As with any forecast, actual journey times may differ from the modelled results because traffic conditions vary from day to day.

Other impacts

To enable the delivery of the proposed new cycle infrastructure, some trees will need to be removed. The locations of these trees are shown on the consultation maps. If any trees need to be removed as part of the scheme, we will seek opportunities to provide replacement trees in nearby locations, as has been done on other schemes.

During the detailed design stage, we will also continue to explore opportunities to introduce additional tress and other green infrastructure wherever possible. TfL's green infrastructure and biodiversity policies focus on protecting, connecting and enhancing green infrastructure across its network.
