County council bosses are watching out for the outcome of a trial testing out the UKs first 3D crossing and, if it is a success, it may look to bring them to Devon. The optical illusion, which creates a floating effect, has been introduced in London by Westminster City Council as part of a 12-month trial. The move follows the creation of similar schemes in other countries. Councillor Stuart Hughes, Devon County Councils cabinet member for Highways said: Im following the 3D crossing trial in North London with interest. The outcome will help us decide if a similar trial should be conducted in Devon. Email email@example.com to tell us what you think. Do you think it is a good idea?
