A grass bridge for walkers, cyclists and horse riders is one of the project's green schemes.

A “landmark” agreement will see green issues take centre stage in the planning of Gloucestershire’s road networks.

National Highways and Natural England have signed a memorandum of understanding on the £460m A417 Missing Link project.

The Gloucestershire Way Crossing, a 37m (121ft) bridge over the A417, will be funded by a £402m investment into environmental schemes which “maximise biodiversity and ensure conservation”.
