A47 Alliance / Upgrade
There is a group of councils and others (including the RAC) calling itself A47 Alliance with a website at http://www.a47alliance.co.uk/ calling for a road upgrade.
The A47 is a significant barrier to cycling in many places, such as the single-carriageway stretch from Tilney All Saints near King's Lynn to Swaffham that blocks several desired east-west cycle routes - it is narrow with much heavy HGV traffic, so it's a challenge to cross and feels no fun for most people to ride along. It is possible that any upgrades could be "cycle-proofed" (to use current jargon) to unblock these routes.
KLWNBUG has asked if CycleNation and CTC groups can be be invited to join the alliance.
