The 1936-37 ‘Report on Indian Railways’ <ref>[http://hdl.handle.net/10973/18160 “Report by the Railway Board on Indian Railways for 1936-37. Vol. I; Railway Department, Government of India” page 45 pdf 62]; Retrieved 6 Nov 2020</ref> gives the following :-
“Bridge No 19 at mile 286 on the ‘{{Assam Bengal Railway]]’(ABR) consisting of 2’ x60’, 2’ x 40’ and 1 x 147’6” girders , had proved a source of anxiety to the Administration for several years. Built in 1898, the south end and centre were destroyed by floods in July 1915. It was rebuilt and reopened in 1920, but in 1928 and later movements were noticed, which upon investigation proved to be due to the slipping of the entire hillside on which it was built. As the destruction of the bridge would have caused complete interruption of traffic for anything from six to ten months, and owing to the depth of the ravine trans-shipment would have been practically impossible. It was decided therefore to replace it with a 20 ft(6mtr) diameter reinforced concrete barrel and an eartfill on a new alignment at a cost of Rs. 2.16 lakhs. The concrete barrel was completed during thge year and good progress made with the earthfill”
