Cutting a dozen or more miles off the A9 route north, and bypassing towns such as Beauly, Muir of Ord and Dingwall, the Cromarty Bridge has significantly shortened the route north from Inverness. It was opened as part of major improvement works, which also saw a new stretch of road constructed across the Black Isle. Built in 1979, a couple of years ahead of the Kessock Bridge to the south, it did not immediately become the A9. Whilst maps from the intervening years show the road from Ardullie to North Kessock is shown as an A road, it is not given a number.
The bridge is a multi-span concrete structure starting with a causeway section on the southern shore, and a much shorter embankment on the northern shore. The piers are paired under the deck, with the road, or at least the pavements, cantilevered out to either side. The whole structure is about a mile and a half long, terminating in a roundabout with the A862 on the north shore.
Long before the bridge was built, indeed probably before cars became a common sight in this part of the country, there was a ferry crossing a few miles to the west from Dingwall to Alcaig. There is also the still surviving Nigg Ferry at the entrance to the Cromarty Firth, but all other traffic would have needed to head inland to Conon Bridge.
