An assessment of the impact of the London Gateway port on road congestion in Essex was made as part of the Government decision giving consent for the port. The then Parliamentary Under Secretary of State, my hon. Friend the Member for Lincoln (Gillian Merron), was satisfied that the impact of additional road traffic in Essex resulting from the port would be adequately addressed by the proposed highway capacity improvements set out in undertakings given by the London Gateway port promoters to Essex county council.
