This offramp is a few dozen yards west IRL

Described locally as the "stone bridge" (as one side has a stone wall) and "Landshipping Bridge". It's more like a dyke with a gap than a bridge. Grass grows on top and there is only a small gap through for water.

There is a lagoon here that, at high tide, seems larger than on this map. It has salt-marshy areas, from a distance looks like large areas with reeds growing etc.

There are public footpaths in this area listed on OS maps but not here.

Sign says "Landshipping Quay" but the sign is the name of the settlement, the UK uses another style of sign for roads.

New roundabout here and another one somewhat further north on West Lane. They changed the road layout after building very large warehouses nearby.

Allotments here. Photos are of the allotment and the path going up to it (grassy/muddy). The gate has a lock, I couldn't get in to properly survey.

Sign implies it's open only to local tenants. URL on the sign just gives 404s. Actual site doesn't show this allotment site: https://www.nottinghamcity.gov.uk/leisure-and-culture/events-markets-parks-and-museums/parks-and-open-spaces/allotments

The site is clearly being used, though.
