I know this has been proposed before, but I wanted to add an issue to Cyclescapes in the hope that it might come up again. We can collect reports and evidence here.
Reopening the Belmont Viaduct to cyclists and pedestrians could greatly shorten and improve a lot of journeys into and across Durham.
Previously Durham Council (before the County Council?) were awarded lottery funding for this. I think the issue was with landowners, and so the funding got diverted to projects outside of the city.
