We will make changes on the stretch of the A406 Gunnersbury Avenue between Chiswick roundabout and Popes Lane to improve the safety of drivers, cyclists and pedestrians.
Works that began in January 2019 will continue through to the summer.
All roads around Gunnersbury Avenue will stay open during the works and there will be access to properties. However, some temporary lane closures will be needed and the area may be busier than usual.
We developed proposals to improve safety on this section of the A406 North Circular because of the number and severity of collisions and near misses there.
We will update this page with details and dates of phase three nearer the time.

Pedestrians and cyclists will have access along the A406 Gunnersbury Avenue at all times. Any temporary changes will be clearly signed.
Normal working hours are 07:30-17:00 on weekdays and 09:00-17:00 at weekends. All working times are agreed with the London Borough of Hounslow.
We will make every effort to reduce noise and disruption where possible. However, some noise is unavoidable.
We are working on this project in partnership with Conway Aecom.
We are working closely with the London Borough of Hounslow to minimise disruption and ensure the works proceed as safely, efficiently and as quickly as possible.
We consulted on these plans in early 2016. Our consultation summary report can be found on the A406 Gunnersbury Avenue consultation page. 75% of people who responded said they supported or partially supported our proposals.
