The single-span steel bridge will replace the existing concrete bridge which was immediately closed to traffic over 7.5 tonnes because of the poor condition of the structure.
It will provide safe access to vehicles up to 44 tonnes across a width of 4.2m, including a 1m pedestrian walkway.
The original Bernera Bridge was built in 1953 and is believed to be the first pre-stressed concrete road bridge in the UK. The vital transport corridor connecting the two islands crosses Loch Roag, a fast-flowing inlet of the Atlantic.
The Delta bridge design alleviates the need for intermediate piers, allowing quicker, easier installation – a significant advantage, particularly in time-critical projects such as this.
Michael Treacy, CEO Mabey Bridge, said: “We’re delighted to be supplying the first Delta bridge to Scotland, and proud to have been selected to take part in this important project to restore a vital crossing to the benefit of the residents of Great Bernera.”
The Delta bridge in Scotland is expected to be completed this summer.
