Today a wood-decked footbridge spans the river which once carried the railway.
Continued expansion of the works required a second bridge to be constructed in 1922, to carry the railway over the river channel.
The new wooden viaduct of 1846 carries the railway.
Originally, the bridge carried just the railway (a single track).
The canal is crossed by two swing bridges, one carrying the railway and the other the A835 road.
The bridge, actually two separate bridges carries the railway Saltsjöbanan and a road.
The base of the swing bridge which carried the railway over the canal is still present in Spike Island.
Nearby, a 19th-century viaduct, built outside Larbert, carries the railway into town.
The earthworks, embankments and cuttings that carried the railway into the town are clearly visible on the bare ground.
A bridge once carried the railway over the A482, but this has since been dismantled, although the track bed still remains in both directions.
