I’ve just found out that the plans for the Rainhall Road bridge (No. 11) are held at The National Archives, Kew.
They are in RAIL 491/1205 and shows plan, elevation and sections in 3 parts. It is dated 1911 and has not been digitised.
The MR seems to have been considering quite a lot of work at Barlick in this period including a footbridge and subway for Station Road, probably killed off by WW1. It would tie in with the visit by the MR photographer in 1913 and shown in Midland Record 7.
