Some loose ends were left behind because of the abandonment. Amongst the most infamous examples are the access to the unbuilt south section at Tradeston which was left as a "ski-jump" (the road abruptly terminates in mid-air, and has remained so despite the 2010 M74 extension, as other plans were used to link the roads), the tangle of slip-roads at Tradeston, and the two infamous "Bridges to Nowhere"; a concrete podium over the Charing Cross section that was left empty for nearly 20 years before finally acting as a base for an office building constructed in the early 1990s (this was always its intended purpose although it had the appearance of an overbridge) and a pedestrian bridge over the carriageways that terminated in mid air as a result of the incompleteness of the adjacent Anderston Centre commercial complex. Signs saying "Ring Road" were still displayed both above and on the approaches to the central section until the late 1980s. The Anderston pedestrian bridge was finally completed in 2013 when it was joined to Waterloo Street as part of a cycle route.
