It was built between 1865 and 1867 for the Midland Railway extension from Bedford to London St Pancras. The ceremony of laying the first brick was performed on 27 January 1865[2] by Mr. Price, the chairman of the company, at Barham Road, Haverstock Hill. The contract price for the tunnel was £250,000 (equivalent to £30,190,000 in 2023).[3]

The last brick was laid on 20 June 1867 by the chairman when the directors of the railway travelled along the line between Bedford and London.[4]

The construction of the line out of St Pancras consisted of four tracks for the first 6 miles (9.7 km), with the exception of the Belsize Tunnel which only had two tracks.[5] This was remedied in 1884[6] by the completion of another tunnel running parallel, to allow the full route of 6 miles to expand to four running lines. It was built under the Midland Railway (Additional Powers) Act, 1881.[7] The additional tunnel was designed by W.H. Barlow, with James Campbell as reference engineer.[8]

It comprises two tunnels 1 mile (1.6 km) long plus strainer arches and buttressed cuttings in the east arch.[9]
