At the same time roads and streets also make up 80% of London’s public spaces, providing vital places for green infrastructure, local markets, community events, and café culture. Balancing the needs of our roads to accommodate increased movement, while creating safe and distinctive places is a key challenge this exhibition explores.

London’s road network can be traced back to Roman Britain and the medieval expansion of the City of London. In the 20th century the motorcar began to dominate city planning and the capital saw the construction of a series of new arterial ring roads. Today we are more conscious than ever of the need to balance the impact of roads on the health and vitality of the city.

Through extensive footage and imagery, “Streets Ahead” offers an in-depth exploration of a range of proposals, both short- and long-term, that will radically reshape the city. New technologies will enable us to rethink how we monitor, repair and manage London’s roads. Intelligent transport systems will use live data to assess the condition of London’s streets and manage the process of road works without impacting on traffic flow. Even buses could use ‘intelligent’ sensors to pinpoint congestion, indicating where repairs are needed, and learning more about passenger movements to help improve the service. Many areas of growth and regeneration sit along key transport corridors and we will see huge transformations in public space, such as Elephant and Castle which is undergoing radical changes to form a new civic heart that extends from the site of the shopping centre.

Longer-term plans envisage dramatic potential changes to city infrastructure and lifestyle with tunnels dissecting through London; driverless cars winding through the streets of the capital; drones replacing delivery services; and highways converted into parks and public spaces. Tunnels – including major orbital and cross-city routes – have great potential to reduce congestion, perhaps by even up to 20% in central London. They would also result in more reliable journeys, improved air quality and lower noise levels, and allow removal of infrastructure routes that blights some areas. Models, renders and videos will offer a glimpse into future London, not only demonstrating where these tunnels would be positioned but also how it will look and feel to use them. With traffic underground, the land above could be developed for social and economic uses, such as new housing, shops and high quality public spaces, with opportunities for public transport and cycling. Such projects have been successfully delivered in cities around the world, such in Hamburg where sections of the A7 national motorway west of the city are being decked over with parks, trees and allotments for adjacent neighbourhoods.
