The building of the Meadowhall shopping centre on the site of a former steelworks in 1990 was a mixed blessing, creating much needed jobs but speeding the decline of the city centre. Attempts to regenerate the city were kick-started by the hosting of the 1991 World Student Games and the associated building of new sporting facilities such as the Sheffield Arena, Don Valley Stadium and the Ponds Forge complex. Sheffield began construction of a tram system in 1992, with the first section opening in 1994.
