London Underground has advised passengers catching the Northern line at Elephant & Castle to use the Bakerloo line entrance in London Road during work to refurbish lifts at the station.
Refurbishment work on the lifts from the Northern line ticket hall next to Elephant & Castle Shopping Centre is due to start on Tuesday 4 March and will continue until late September.
"This is crucial work to improve the reliability of the lifts at Elephant & Castle," said Peter McNaught, London Underground's operations director.
"In order to keep the station open and minimise disruption, we will be working on one lift at a time and keeping one lift open in the Northern line ticket hall.
"Customers can avoid queues to enter and leave the station by using the Bakerloo line ticket hall entrance, where three lifts are available.
"The Bakerloo line ticket hall is just on the other side of the roundabout and a walking route will be clearly signed."
LU says that access to the staircase from the Northern line ticket hall will be restricted "for safety reasons".
Tube bosses have also reminded passengers that they can use First Capital Connect train services from Elephant & Castle Railway Station to reach several Northern line destinations including St Pancras International and Kentish Town.
