Tram customers will face further disruption as the ongoing £32million rail replacement project moves into a new phase next week.
A revised timetable with fewer trams each hour during the day will be in operation on the yellow and blue lines for around five weeks, with the purple route not running.
The second phase of work this year between White Lane and Halfway is coming to an end and is due to be completed on time, with services to be restored from Halfway from Monday.
But the next stage of work will begin the following day on Cricket Inn Road, Parkway Viaduct in both directions and at the junction at Woodburn Road.
Revised timetables will mean that during the day, the yellow and blue lines will operate a 12-minute frequency rather than 10 minutes.
From Hillsborough to Fitzalan Square trams will run every six minutes.
The purple route will not run during the works and a bus replacement service will run between Gleadless Townend and Herdings Park to connect with trams at Gleadless Townend.
But works will be suspended on July 5 and 6 as the Tour de France comes to Sheffield, with an enhanced service on the Sunday.
Tram network owner South Yorkshire Passenger Transport Executive and operator Stagecoach Supertram are funding the project, with most work being undertaken during the next four years.
Tracks have already been replaced between Spring Lane and Park Grange Croft, as well as in the Hillsborough-Malin Bridge area.
