Dudley Tunnel was popular with tourists and was mentioned in guides to Dudley Castle written by The Rev. Luke Booker in 1825 and W. Harris in 1845. There were complaints that the tunnel was often blocked by unattended limestone boats but this problem seems to have been resolved by 1799 although there is no mention of how this was achieved. The tunnel was also affected by subsidence from local coal mining and was regularly closed to allow repairs to be made. Working a loaded boat through the tunnel took about 4 hours and this caused congestion. Various ways were considered to alleviate this, including rope haulage in 1840, but the cost of £6,000 was deemed to be too expensive. Subsidence in the Lapal tunnel was worse and it was closed twice in 1801 and for four months in 1805.
