Cromarty Bridge will be closed overnight at the weekend next month.
Refurbishment work will be carried out at the bridge on Saturday, October 1, from 7pm until 6am.
Workers will remove the temporary barrier system from the east side of the crossing.
The timings of the closure have been planned to take place off-peak to minimise disruption to the travelling public.
A signed diversion route will be in place with motorists diverted from Tore Roundabout to Ardullie Roundabout via the A862 through Dingwall and vice versa.
The majority of the parapet works took place at night from February to this month.
It is one of the four schemes to take place on Cromarty Bridge within 2016, totalling more than £4million of investment by Transport Scotland.
Consultation has been carried out with Emergency Services, transport operators and Highland Council ahead of the planned bridge closure.
Eddie Ross, BEAR Scotland’s north west representative, said: “We are pleased to complete the final stages of the parapet replacements on Cromarty Bridge, with the removal of the temporary barrier allowing the bridge to be reinstated to its full width.
“Due to the nature of the work, a closure of the bridge is required to ensure the safety of our teams as well as for the protection of motorists.
“A diversion through Dingwall will be in place and we will look to complete the works as quickly and safely as possible.
“We’d advise motorists to plan ahead by checking the Traffic Scotland website and leave some extra time for their journey.”
