Map feedback we have received:

"NCN7/75 in Glasgow is diverted for (at least) six months at the foot/cyclebridge over the M8 and railway line. At the moment the diversion is very badly signposted (as a pedestrian diversion). There are two alternative footbridges, both have steps in the access ramps (OK for a fit (conventional) cyclist to get up but definitely not DDA compliant)
Details apparently available at swtrunkroads.scot"

Presumably this is this location?
