Major roads investment in London and the south east

£1.4 billion package for 18 new road schemes in London and south east of England.

This was published under the 2010 to 2015 Conservative and Liberal Democrat coalition government


An ambitious £15 billion plan to triple levels of spending by the end of the decade to increase the capacity and condition of England’s roads, was announced to Parliament today (1 December 2014) by Transport Secretary Patrick McLoughlin and Chief Secretary to the Treasury Danny Alexander.

London and the south east of England will benefit from 18 new schemes worth around £1.4 billion creating an estimated 900 construction jobs.

Patrick McLoughlin said:

Today I am setting out the biggest, boldest and most far-reaching roads programme for decades. It will dramatically improve the network and unlock Britain’s economic potential.

Roads are key to our nation’s prosperity. For too long they have suffered from under-investment.

This government has a long-term plan to secure the country’s future and this £15 billion roads programme is a demonstration of that. It will directly benefit hardworking families across London and the south east.

This is the biggest investment in roads in a generation and will update major corridors in and around London and the south east, including the M25, A27 and A34.

A radical overhaul began in 2010 with the following major improvements in the area:

  • an upgrade to the M25 to create 4 lanes throughout by the end of 2014
  • the newly widened A23 which has opened south of Crawley
  • dualling of the Tonbridge bypass which is expected to begin next year

Spending during the next parliament on the local and national roads network across London and the south east will be boosted further by maintenance funding worth £1.9 billion.

Chair of the Cabinet Infrastructure Committee and Chief Secretary to the Treasury, Danny Alexander, said:

World class infrastructure is vital if we are to build a stronger economy, but it matters in other ways too. It invigorates communities and gives people more opportunities to get on in life. This is why I have ensured that this government has prioritised funding roads, and railways, at a high level for future generations.

For decades our roads have suffered from under investment, so I’m particularly delighted to be able to announce this expansive range of new road schemes today. Investment on this scale is only possible because we have taken the difficult decisions needed to control our public finances and stuck to our recovery plan which is now delivering strong growth and record numbers of jobs.

These projects, like the scheme on the A27 around Arundel, will help unleash the economic potential of both the regions they serve and of the overall economy.

Chancellor of the Exchequer, George Osborne, said:

I promised when I was in the south east that we would address this area’s economic needs for the future.

Our Long term-economic plan means today we can invest £1.4 billion into the region’s infrastructure to improve, repair and expand our roads.

Our plans will transform some of the country’s most important strategic routes, such as our ambitious projects to improve the M25 and A27, and spending on important local infrastructure will boost productivity and help the local economy of the south east.

For years our roads have been neglected. Now that this government is fixing the economy, we can afford to invest properly in our roads – unlocking jobs and local growth by creating a road network that is fit for the 21st century.

Highlights of today’s announcement are:

  • improvements will be made to around 10 of the 31 junctions on the M25, including
    • expanding junction 30 to improve access to the new London Gateway port
    • a major rebuilding of junction 10, improving the least-safe junction on the motorway network
    • significant capacity enhancements between junctions 10 and 16 on the main carriageway, with new smart motorway technology to improve capacity and ease congestion
    • a strategic study to look at long-term answers to conditions on the south-west quadrant of the M25, that can make the route effective for a generation to come
  • investing around £350 million to transform the A27, with a new bypass at Arundel to complete the ‘missing link’, plus further improvements around Worthing, Lancing and Lewes - this will help the A27 link together as a single route, supporting the development of the local economy and removing notorious congestion hotspots
  • better access to ports, through
    • enhanced junctions on the A20 in Dover, for better access to the port and supporting new homes and jobs
    • improvements to the M271 Redbridge junction, required to get to Southampton docks
  • the A34, the main route from the Midlands to Southampton, will see investment of £30 million to ensure a crucial freight link and enhanced junctions will improve journeys around Oxford and Winchester
  • the A31 at Ringwood will be widened to help local traffic crossing the Avon and substantially improving safety
  • a new feasibility study will look at creating an expressway link between Oxford and Cambridge via Milton Keynes, fixing a long-standing gap in the network and bringing new capacity to support the growth of Bicester
