Why we need this scheme
This section of the M25 experiences congestion throughout most of the day with performance susceptible to frequent incidents on the adjacent highway network. It directly services the port of Tilbury and the Lakeside regional shopping centre and is regarded as the last major transport constraint to the development of the Thames Gateway area. As development gets under way traffic growth will increase and congestion worsen. Traffic is forecast to grow by 25% by 2032.
We've developed the scheme within the existing highways boundary. Our proposals are:
- online widening in both directions between junction 30 and the A126
- improvements to the junction 30 slip roads
- introduction of dedicated left-turn lanes from the A13 to the M25 northbound and M25 southbound to the A13 eastbound
Our main objective is to improve capacity of the highway network centred on M25 junction 30 and in particular the A13 through junction 30 and to the junction with the A126, an area recognised as the biggest remaining constraint to the development of the Lower Thames Gateway.
We've carried out air quality assessments and there are no perceptible increases of NO2 or PM10 concentrations at receptors as a result of the scheme. However, we predict the scheme will lead to small decreases at 7 receptors which currently exceed the NO2 AQ0. Air quality impact has been assessed as low.
Existing noise mitigation will be retained or replaced as necessary. Short term and long term noise impacts as a result of the scheme in operation are predicted to be negligible, with no perceptible noise changes being predicted.
During construction, there is potential for noise impacts to properties nearest the works. All construction will be carried out under a Section 61 noise agreement. This ensures control measures are in place, as established between the contractor and the local authority's Environmental Health Officers.
The scheme will include replacement planting to soften and integrate the improved road into its surroundings as far as possible.
Effects on cultural heritage were assessd as neutral.
A range of birds, mammals, reptiles and plant species are present within the scheme boundary. We'll retain existing habitats as far as possible and provide new replacement habitat as required.
Reduction of flows and pollution control devices for the drainage network will be included in the scheme to ensure there is no adverse impact.
No disruption of current land use is envisaged.
