Work to repair a major road that connects an island to the mainland will start later.
Ferry Bridge, which carries the A354 between Portland and Weymouth, will be partially closed for structural repairs after cracks started to show in its concrete.
One lane will be open with two-way traffic lights and abnormally heavy vehicles that exceed normal legal limits will not be allowed to use the bridge.
The closure is expected to last until 1 March. Pedestrians and cyclists will still be able to use the bridge throughout the work.
