Work to reduce the risk of flooding to homes and businesses in Cumbria is due to start.
Culvert replacement work, carried out by the Environment Agency, will begin in Appleby in January.
The work aims to reduce the risk of collapses and blockages in the underground Doomgate watercourse.
Preliminary work will start at the junction of Holme Street and Doomgate on 10 January. Some roads will be closed to allow the work to take place.
Sections of Shaw's Wiend could be closed for up to two-and-a-half months.
There may also be disruption on to the road from Colby Lane.
Mike Harper, Environment Agency project manager, said: "It is essential that we carry out this work, to bring the culverts up to the required condition and restore their capacity, to reduce flood risk to the town.
"Unfortunately, due to the nature of the works, this will mean some unavoidable road closures and we apologise for any disruption this essential work may cause."
