There is a proposed project idea floating around called the Thames Deckway, which would function as a floating highway that would run east-west along the river’s southern bank for about seven miles, from Battersea to Canary Wharf.
The River Cycleway Consortium said in a statement, “London needs to think outside the box of conventional solutions to solve its deep-seated traffic and pollution problems. The river Thames, London’s main transportation thoroughfare from Roman times up to the 19th century, is overlooked today as a major travel artery except for a handful of passenger boats.”
The floating highway is literally just as it sounds. It would float with the tides of the river and sensors along the route would monitor weather and storms in order to notify riders.
The cost of the project is estimated to be around $960 million, although rumors are that the highway would generate its own energy through a combination of solar, tidal and wind power.
Right now, plans are to raise money for an in-depth study on the viability of the idea and then to look for private investors interested in covering the construction costs.
