Clachan Bridge

Clachan Bridge is a stone arch bridge in Argyll and Bute that links mainland Scotland to the island of Seil. It crosses the Clachan Sound with a single arch and carries the B844 road for everyday traffic between the two shores.

Engineer Robert Mylne built this bridge in 1792 to connect the mainland with Seil and support maritime trade. The structure was later listed as a category A building, marking its importance as a work of Scottish engineering.

The nearby Tigh an Truish pub sits where islanders once changed out of kilts into trousers after the 1745 Highland dress ban took effect. The location holds memory of a time when people had to hide their traditional clothing to live safely.

The bridge is open to traffic daily and provides straightforward access between the mainland and Seil. It is wise to drive carefully, as the structure is narrow and the road can become slippery in poor weather.

The narrow waterway beneath carries connections to the Atlantic Ocean at both ends, earning it the nickname Bridge over the Atlantic. This geographical feature makes it an unusually positioned link between two relatively close landmasses.
