The Mayor's Roads Task Force report aims to ensure the capital can cope with major population growth, support jobs and thousands of new homes in the coming years.
The ambitious £30 billion road improvement plan for London was produced by a task force set up by Mayor Boris Johnson.
The 20-year vision includes improvement to the North and South Circular roads, new "flyunders" and major schemes at Vauxhall, Waterloo, Elephant and Castle and Old Street.
There are also plans for improved bus services, more 20 mph zones, and proposals to improve cycling and walking.
The 100 designs from 21 countries submitted to a competition run by the Royal Institute of British Architects will be displayed around Vauxhall's riverside, railway arches and small parks.
Entrants were encouraged to take inspiration from New York's High Line - an historic elevated railway that was turned into a leafy urban park - to make green links along the river and through the parallel viaduct.
Chris Law, from the Vauxhall Vauxhall One Business Improvement District said:
"There is a lively variation of ideas and many reoccurring themes. Our aim is to help create a great public realm for Vauxhall."
On April 15, a shortlist of three, plus a student winner, will be chosen. The shortlisted four will be asked to submit more detailed proposals.
