The M80 motorway crosses the River Carron immediately to the west of Denny on a pair of bridges. Each carriageway is carried on a separate, but identical structure, spanning the river, with a riverside path running underneath on the south bank.
The two bridges appear rather spindly from below, with slender concrete beams forming a pair of arched trusses under each road deck. The decks are supported by slender concrete pillars which support transverse beams. However, as they have supported two lanes of motorway for many years they are obviously more substantial than they appear!
