The Connel Bridge was constructed by a firm called Arrol, of the Germiston Iron Works, Glasgow[2] It was engineered by John Wolfe Barry.

In 1909, however, an additional train service started running between Connel Ferry station and Benderloch on which road vehicles could be transported over the bridge.

A single car was carried on a wagon hauled by a charabanc that had been adapted to run on rails at St. Rollox railway works in Glasgow.

After the branch line closed in 1966, the bridge was converted for the exclusive use of road vehicles and pedestrians, and the toll was removed.

[2] The large span without supporting piers was necessitated by the strong tidal currents of the Falls of Lora, just to the east of the bridge.
