In a press release the trust said it also plans to run a public fundraising campaign later in the year "so that people can be part of the project".
Updated construction plans were approved by Lambeth Planning Committee on 16 December, although the trust must still meet dozens of conditions before the bridge can proceed. The trust said further planning meetings are scheduled with Lambeth and Westminster Councils to discharge all planning conditions.
The trust also still needs to secure a lease on the land for the south bank landing site. Coin Street Community Builders, which owns the site, has previously indicated it will follow the decisions made by politicians.
The trust aims for the construction contract to be signed early in 2016 with construction beginning in the summer. Works are scheduled to begin in the spring with the moving of HQS Wellington to its new location about 100m down the River Thames, to provide access to the northern landing.
The trust has raised £145m towards the overall cost of the project, which is £175m. Of this, £85m has been raised privately by the trust in 18 months, the trust says.
