The A82 crosses the Douglas Water at Inverbeg on the banks of Loch Lomond. Those who use the road will be familiar with the Inverbeg Inn (recently rebranded as the Inn on Loch Lomond) and holiday park, but perhaps few realise that the road crosses a bridge here. Even less will know that there is a rich history of old bridges to be discovered just a short distance upstream.

The Old Bridge

The oldest crossing here is to be found a short distance upstream from the A82, acting as access to the Inverbeg Gallery from the Glen Douglas road. The downstream face is easily visible, and appears to be a relatively modern concrete arch structure, built on a curve to facilitate the difficult turn that the road takes as it loops away from the lochside to cross the river. However, closer examination will reveal that the bridge has been widened and that this is the newer side, probably dating from the 1930s.

From the river bank to the west of the bridge, it is clear to see that this is a much older bridge, built of rubble stone and now held together with iron straps. The parapet is new, built when the bridge was widened, and some of the other stonework has been replaced - probably. The true date of this part of the bridge is uncertain. It presumably dates from at least the 1810s when Telford rebuilt the military road up Loch Lomondside. However, the stonework suggests that this could actually be the bridge built by Caulfeild in the late 1740s, as such bridges seem to have been built without parapets and were designed to use the minimum of stonework.

Newer Bridges

Next we come to the bridge that crosses the water between the old bridge and the modern bridge - in chronology at least. It also once stood in reality, but has since been demolished. The evidence for its existence is the line of the tarmac on the Glen Douglas road, which comes up from the A82 and turns to terminate at a wall on the riverbank, while a different section of tarmac, much narrower, continues the road up the hill. This is clearly the site of an old bridge, probably added in the 1950s or 60s to remove the tight bends of the old road over the surviving old bridge. At present its design can only be speculated at.

The A82 now crosses by another bridge, built wider and straighter than any of its predecessors, and crossing the river in two spans with a concrete pier sitting in the river. The bridge carries a wide S2 carriageway, with pavements cantilevered out from the pier and abutments on a substantial concrete deck. Metal railings act as parapets.
