The construction of the tunnel was not the only problem encountered in building the difficult section of the railway between Waterval Onder and Waterval Boven. Not far below the tunnel, the line had to cross the Dwaalheuwel Spruit. The N.Z.A.S.M. built a fine five-arched bridge of dressed stone. The bridge was opened to traffic on 20th June, 1894, and the rack railway ran over it until its use was discontinued. Thereafter the bridge was converted to a road bridge and continued to serve this purpose for many years.
