The Royal Borough of Greenwich and Newham Council have begun a major campaign for two new river crossings between East and South East London.
They are calling for a new tunnel between Greenwich Peninsula and Silvertown, and a new bridge at Gallions Reach between Beckton and Thamesmead.
Both authorities say the crossings would promote economic growth in the area, as well as relieve traffic congestion.
Transport for London are consulting on the river crossings package with the consultation running until 1 February 2013.
