'''Knowlesands Tunnel ''' (Bridge 32) is the shorter of the two tunnels on the present day SVR, being just over only 40 yards long2 feet in length.<ref name=Marshal>[[Bibliography#Books|Marshall (1989)]] pp. 40, 104. </ref> It is located between on the 1 in 100 climb from [[Bridgnorth]] and towards [[Hampton Loade]], just north of milepost 149, between [[Bridgnorth signal box|Bridgnorth Down Distant and Down Outer Home signals]]. The main B4555 Bridgnorth-Highley road passes over the railway at this location, but the railway is not visible.
In common with other portions Although the foundation and bridges of the original Severn Valley Line it was built were laid out to accommodate a double track at a later date, so [[Mount Pleasant Tunnel]] and [[Bridgnorth Tunnel]] were both built to single track width as an economy measure, while [[Bewdley Tunnel]] on the later [[Kidderminster Loop Line]] was also built to single width. However Knowlesands Tunnel was classed as an overbridge and therefore has much more clearance than other tunnels, having a segmental arch roof of 25ft span.<ref name=Marshal>[[Bibliography#Books|Marshall (1989)]] pp. 40, 104. </ref> 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.
On [[Severn Valley Railway Timeline 2000-2009#2000|5 November 2000]] torrential rain caused a major landslip at the Bridgnorth end of the tunnel with 3 lengths of track left hanging in space and the embankment spread across the field below. Contractors completed the reinstatement later that month<ref>SVR News 134</ref>.
