While tracks and points are being replaced around The Forest, trams will be unable to run between Wilkinson Street and Old Market Square, and a dedicated replacement bus will operate between the two stops until the completion of the works on August 31.
A full tram service is set to resume on Friday, September 1.
In the meantime, the replacement bus will operate every ten minutes to connect with the rest of the tram network, and members of the NET Customer Experience team will be on hand to offer travel advice to passengers who are also being asked to allow extra time for their journeys.
Buses on this section of the network will also be accepting tram tickets.
Trevor Stocker, NET Head of Operations, commented: “We would like to thank customers for their patience and understanding while this essential work is carried out as part of planned infrastructure renewals that are vital for the safety and reliability of future tram services.”
