Olive Mount cutting, which was opened in 1830, is a 2-mile (3.2 km) sandstone railway cutting on the line to Manchester, 4 miles (6.4 km) from Liverpool. The cutting is 80 feet (24 m) deep and is situated between Wavertree Technology Park and Broad Green railway stations. The railway's engineer, George Stephenson, had hoped to avoid the problem of creating the cutting for the Liverpool and Manchester Railway by routing the line further north. However, that plan was objected to by the Earl of Derby and the Earl of Sefton.
