All lanes have been restricted in both directions over the Erskine Bridge due to high winds.
Traffic Scotland announced the change from 6:37am on Tuesday morning.
Western Ferries, which operates crossings between Gourock and Dunoon, also said on Tuesday morning that it had suspended its service due to high winds.
It comes as a number of households across Scotland remain without power following storms Malik and Corrie.
In an update on Monday evening, Scottish and Southern Electricity Networks (SSEN) was at red alert level as it responded to “significant damage” caused by the storms.
As of 8pm, they said that power had been restored to around 100,000 customers, with about 16,900 remaining off supply.
SSEN said that the he main areas which continue to be affected are rural Aberdeenshire and the Angus border, with some customers also off supply in Perthshire, the Highlands, Western Isles and the Moray Coast.
With support from over 400 additional engineers and support staff, SSEN’s teams sought to reduce the number of customers off supply to around 7000 overnight.
They added that restoration efforts will continue into Tuesday with the possibility that for small clusters of customers affected by Storm Corrie, this may extend into Wednesday.
Meanwhile, service largely returned to operation on Scotland’s railways on Tuesday morning following disruption caused by the weather.
Network Rail announced that lines between Aberdeen and Inverness, and Inverness and Edinburgh/Glasgow Queen Street, have now fully reopened.
They said that the only routes that remain closed after Storm Corrie is between Inverness and Wick/Kyle.
