Knowlesands Tunnel (Bridge 32) is the shorter of the two tunnels on the SVRSevern Valley RailwaySVRA:Severn Valley Railway AssociationSVRS:Severn Valley Railway Society, being just over 40 yards long. It is located between Bridgnorth and Hampton Loade, just north of milepost 149, between Bridgnorth DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) Distant and DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) Outer Home signals.
In common with other portions of the original Severn Valley Line it was built to accommodate a double track at a later date, so has much more clearance than other tunnels. Insufficient traffic materialised to justify the widening to a double track. The main B4555 Bridgnorth-Highley road passes over the railway at this location, but the railway is not visible.
