Rail replacement programme (2013–present)

The latest phase of rail replacement works on the Supertram network began in July 2013. Work is currently suspended pending the start of Phase 2 of the project from the end of March 2014.
==Phase 1 (2013)==
Phase 1 of the works took place in the summer of 2013 between July and September, however over-ran into the beginning of November. Phase 1 was between Sheffield Station tram stop and Spring Lane tram stop with the rail replacement being at Park Grange Road. A dedicated bus service ran between the two stops as express (B1) or stopping (B2)
At weekends, and occasionally weekdays during the works, there were more minor tram works which affected other services. This brought in the B3 up to Gleadless Townend and the Y1 between the City Centre and Hillsborough. The B2 was often extended during this period.
==Phase 2 (2014)==
===Phase 2a===
Phase 2 of the works starts on Saturday 29 March, 2014, initially taking place between Shalesmoor tram stop and Hillsborough tram stop, with the rail replacements extending to Middlewood and Malin Bridge. This work is expected to be complete by Late April.
===Phase 2b===
Phase 2b affects Blue route services between Gleadless Townend and Halfway between April and May.
===Phase 2c===
Phase 2c affects the Yellow route and the Purple route as Rail replacement works take to the Meadowhall line between May and June between Park Square and Cricket Inn Road.
===Phase 2d===
Phase 2d starts in July and takes the rail replacement works up West Street affecting Yellow and Blue route services. This completes the work towards the end of September.
===Other works===
Minor rail replacement works may also take place at Weekends, however these are currently unconfirmed
