Six community projects have been selected to vie for up to £50m of lottery money through a televised public vote.
Sustrans and the Eden Project are among the organisations shortlisted by the Big Lottery Fund to go through to the second stage of The People's Millions, its televised funding scheme.
The shortlisted organisations will present their project proposals on an ITV programme in 2007, when viewers will be able to vote to decide which project gets the grant of up to £50m.
The organisations have until then to work on their proposals.
Sustrans is seeking funding for its Connect2 project, which aims to connect communities by developing foot or cycle bridges and other links over obstacles such as rivers, roads and railways.
John Grimshaw, chief executive of Sustrans, said: "We will now begin work with communities to identify barriers that separate people from the places where they want to be."
Also competing in the vote are Nottinghamshire County Council, the National Museum of Science and Industry, Somerset County Council and the Black Country Consortium.
The TV vote is part of the £140m Living Landmarks grants programme, which was launched in June 2005 to support large-scale capital projects that transform local environments.
