were erected in key locations, varying from narrower pillars for bus and tram stops and the railway station to much broader pillars outside key attractions, each showing information on the immediate surroundings, a map and (in some cases) a clock. All junctions on the Inner Ring Road have been numbered and marked with a strong landmark feature. Travel information panels in bus interchanges have been made clearer and the YourNextBus system was rolled out onto departure boards at bus stops telling passengers when the next bus is due at their stop using GPS technology. Sheffield's shopping areas are in the process of being redeveloped and when finished will attract business from further afield than ever before. The Moor, once Sheffield's busiest shopping street, is being gradually redeveloped by private owner Scottish Widows and a new £18 million indoor market was opened in 2013, relocating traders from the ageing Castle Market in the Castle Gate Quarter of the city.

It had been on hold since 2008 due to the recession and was cancelled in its current form all together in July 2013 when Sheffield City Council decided to relieve developer Hammerson of their development rights. Sheffield City Council announced in late 2013 that they will proceed with their own development scheme to replace the axed Sevenstone project.
