[[File: Bridge_32_20150610.jpg |thumb|300px|right| The south portal of Knowlesands Tunnel, looking towards Bridgnorth]]This is the shortest tunnel shorter of the two tunnels on the SVR, and being just over 40 yards long. It is numbered as Bridge 32. It and is located between [[Bridgnorth]] and [[Hampton Loade]], just north of milepost 149, between [[Bridgnorth signal box|Bridgnorth]] Down Distant and Down 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.
