For the bridge over Ydseelva in Verdal, which had a main span of only , construction started in April 1903 and was completed on 21 November. The area has quick clay, so the bridge needed piling. At Røra, a spur was originally planned to Hylla, but this was discarded late in the planning phase. At Hellem in Inderøy the right-of-way had to be moved because of poor soil mechanics. There were similar issues north of the Lunnan Tunnel, forcing the tunnel to be extended and a support being built. Construction of the tunnel was performed by 40 men during the winter of 1904 and 1905. It cost NOK 90,179 and took 23.9 man-hours per meter to build.
