Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will make an assessment of the effect on traffic congestion in (a) Brentford and Isleworth constituency and (b) the London borough of Hounslow of the proposed third runway at Heathrow.

The Airports Commission undertook a range of detailed assessments to support its Final Report published in July 2015. The analysis included a detailed assessment of transport network impacts for each of the Commission’s three short-listed options.

Copies of the Commission’s Surface Access: Dynamic Modelling Report its Local and Strategic Roads Modelling Study for the Heathrow Airport North West Runway Proposals, and the Commission’s Freight Impact Study were published alongside its Final Report, and are available from the Commission website at the following links:
