I’ve just found out a road near me is to be part resurfaced, I’ve now managed to get agreement that they consult cycling groups for projects like this, so there is in theory the possibility of changing the road layout.
Preston Road, North Tyneside

Its an A Road, 30 mph, big enough traffic volume that by any sensible measure complete segregation is required. No reasonable alternative cycle routes.
If you take the right of people to park a car outside their house on the victorian terraced sections at the southern end as a given then bike lanes or cycleways are difficult. It looks much easier to put stuff in on the northern end, there are service roads on some sections. I don’t yet know which bits are to be resurfaced and/or remarked.
North Shields Town Centre at one end, local shops midway at signalled cross-roads, secondary school and supermarket at the other. Local policy is that residential areas are 20mph, but the A Roads are excluded from this and remain at 30mph.
