Bonar Bridge (Scottish Gaelic: Drochaid a' Bhanna, pronounced [ˈt̪ɾɔxɪtʲ ə ˈvan̪ˠə]) is a village on the north bank of the Kyle of Sutherland to the west and the Dornoch Firth to the east in the Parish of Creich in the Highland council area of Scotland.

In May 1900, a priceless collection of early Bronze Age jewellery known as the Migdale Hoard was discovered by workmen blasting a granite knoll behind Bonar Bridge, near what is known as "Tulloch Hill".

The Dornoch Firth was the boundary between "Cat" and Ross and was called "Ekkjal" (Oykell) by the Norse and it is mentioned in the Orkneyinga saga.

[13] "In the 11th or 12th century a contest of the inhabitants with the Danes is recorded to have occurred at Drin-leah (Drum Leadh), near Bonar Bridge, whence the invaders were driven back with great loss to their ships at Portnacoulter, [Meikle Ferry].

[14] The oldest records of local place names (on North side of the Kyle) found on maps are (in order from oldest) Sordel (Swordale, from Norse name) which is now a part of Bonar Bridge and has Swordale Farm, Little Swordale (Sordel Beg) (a mixed Norse Gaelic name with "Beag" meaning small in Gaelic) which is now abandoned, Creich (sometimes with Little Creich called out), Migdale then later Tulloch .

On the South side of the Kyle, MidFearn (Ferne 1573)[15] is the oldest location shown, with Kincardine (with its church) appearing next.

The Battles of Invercarron and Carbisdale took place in 1650 during the Wars of the Three Kingdoms close to the village of Culrain, which lies to the West of Bonar Bridge.

Most of the Jacobite officers were captured, many of the men were killed and the rest were driven onto the shore where several were drowned trying to swim the Kyle of Sutherland.

On the night of 16 August 1809 over 100 people boarded the ferry boat on the Dornoch side along with goods and stock for the market in Tain.

The fording point lies slightly downstream from the current bridge, more or less where the "Bonar shot" salmon fishing station was, below the old ice-house below Dornoch Road.

[18] The New Statistical Account for Scotland explains that consideration was given to sites at Meikle Ferry (referred to as Portnacoulter, Port a' Choltair in Gaelic, named for its shape like a "coulter" the blade of a plough) which was considered too wide, at Creich (also considered too wide) and at Portinleck (between Culrain and Invershin) which was further up the estuary and required a longer journey around and also a second bridge across the River Carron.

A plaque on the Ross-Shire side of the bridge was engraved with the following text: "Traveller, Stop and Read with gratitude the Names of the Parliamentary Commissioners appointed in the Year 1803 to direct the Making of above Five Hundred Miles of Roads through the Highlands of Scotland and of numerouse Bridges, particularly those at Beauly, Scuddel, Bonar, Fleet, and Helmsdale, connecting those Roads!"

It was designed by Crouch and Hogg consulting engineers and was built alongside the older bridge while it was still standing (but considered weak and needing renewal).
