River Eachaig


The River Eachaig is a river on the Cowal peninsula, Argyll and Bute in western Scotland.
The river flows from Loch Eck to the Holy Loch, passing Benmore Botanic Garden, Rashfield and Cot House. It is joined by the Inverchapel Burn and the River Massan. The Little Eachaig joins the River Eachaig immediately before it empties into the Holy Loch.
The old route from Inveraray to the Firth of Clyde involved travelling down Loch Eck, then crossing the River Eachaig to get to Dunoon – Mary Queen of Scots went this way in 1563. A small boat or punt called a coite carried passengers over the river, and the thatched house of the ferryman became known as the Cot House, eventually the Cot House Inn.
Around 1835 David Napier built a road from Kilmun pier to Loch Eck as part of the "new route to Inveraray", and at this time the ferry was replaced by a wooden bridge. This in time needed replaced, and around the end of 1884 the Trustees of the Dunoon District of Roads, Argyllshire, arranged for engineers and contractors to construct a new malleable iron girder bridge spanning over the river; this bridge was completed in May 1885. It is a single-span wrought iron double warren lattice truss bridge, spanning between abutments at each end with splayed stone parapets.
This route was still shown in the Ordnance Survey 7th series one-inch map published in 1960, in following decades the A815 main road was realigned with a curve crossing the river on a new bridge to the north of the old bridge, and the A880 side road from Kilmun extended to join this as a side road. The old bridge is still in place, and is a listed building as a rare example of an unaltered wrought iron bridge.
