There are three of these small pyramids standing here in a car-parking area at the riverside, next to Bonhill Bridge; of these, only the one shown in this image bears a plaque (by 2015, the plaque had gone). Its text reads:

"Bonhill Bridge
erected by
the County Council of Dunbarton
was opened for traffic
on 2nd July 1898.

Convener of the County
The Rt. Honble. Lord Overtoun.
Chairman of the Road Board
John Gilmour Esqr."

Note that the plaque does not describe the existing (as of 2009) bridge (see NS3979 : Bonhill Bridge), but, rather, its immediate predecessor.

The white building visible through the trees, in the background, was (when this picture was taken) used by a dental practice.
