Windermere Ferry will be out of service for up to two weeks next month for maintenance work.
Westmorland & Furness Council said the work will help extend the ferry’s working life and improve reliability.
There will be a two-week suspension from Monday February 23.
Services on the Mallard will also have to be suspended for preparatory work on Wednesday January 21 between 9am and 3pm.
During the closure, road users are encouraged to follow the alternative route via the A591 to Ambleside then on to B5286 to Hawkshead.
The suspension is part of planned work to replace and upgrade parts of the driveline system, which have been running almost continually for more than 30 years.
Westmorland and Furness Council cabinet member for highways and ICT Peter Thornton said: “Maintaining the reliability and safety of Windermere Ferry is a key priority for the council.
“We are committed to delivering an efficient and dependable service across the lake and are continually striving to balance delivering a reliable service with the need to carry out maintenance and improvements to ensure that service is deliverable.
“By scheduling these essential upgrades during the low season and outside school holidays, we are working to minimise disruption for our users.
“We appreciate ferry users’ patience during this period and encourage everyone to sign up for our ferry user updates where we will share our progress.”
