Gazeteer of Samuel Brown's works

Kalemouth Bridge
Samuel Brown's Kalemouth Suspension Bridge (c.1835) over the River Teviot near Kelso in the Scottish Borders. It is one of only three of Brown's chain bridges that have survived. Many were destroyed by flood or storm, and many were replaced in the 19th and 20th centuries.
