The National Forest in Leicestershire has been chosen as the site for a proposed East Midlands landmark.
The vault will be visible for miles around
The Sky Vault, a net cable structure suspended from steel arches, will straddle the A42 in North West Leics.
It was selected ahead of four other sites after months of consideration by a panel of designers.
The experts selected the National Forest site because it is an area free from strong, symbolic association with one particular county.
Tom Hughes, one of the judges, said: "Bids from the National Forest and Newark and Sherwood District Council made it to the final stage of assessment. Both presentations were very strong.
"However, it was felt the National Forest site presents the Sky Vault team with the best opportunity to deliver a project that the whole of the East Midlands community can identify with.
"This will help to develop a sense of ownership throughout the region."
The team behind the project, which includes Nottingham Trent University, will decide the exact location for the landmark.
The scheme is being paid for by the National Lottery Landmark fund.
The other areas considered were two sites on the A1 and two locations on the M1.
Detailed designs are to be put to the Highways Agency and the project is scheduled to be completed in summer 2008.
