One of the bridges over the Trent at Clifton Bridge includes a section of the former B680 (which followed the route into Nottingham now used by the A453). The 275 ft east bridge opened in 1958, being officially opened by Princess Alexandra, The Honourable Lady Ogilvy. The bridge was widened, with the west bridge, to dual-carriageway as the A614 as part of a £3.2 million section, opening in 1972. This was the completion of the dual-carriageway Nottingham ring-road. It enters the borough of Rushcliffe where it crosses the former Great Central Main Line and meets the A60 (for Ruddington and the Nottingham South Premier Inn), then the A606 at busy roundabouts. This section from the A606 roundabout, near the Wheatcroft Garden Centre, to the Dunkirk junction (current A6005, then the A453) - the Nottingham Ring Road - was opened in 1963 as mostly single carriageway. The section from Clifton Bridge to the A60 roundabout was dualled in December 1968. The £6 million section from Gamston to Lings Bar opened in September 1981 as "Gamston Lings Bar Road". It passes close to Tollerton Airfield and a large Morrisons (former Safeway), and crosses the Grantham Canal meeting the former route (A6011) at a busy roundabout near the "Bridge" pub. The section from the QMC to the A606 "Wheatcroft Island" roundabout used to be the A614 until the Gamston section was opened. The former route of the A52 into Nottingham is now the A6200 and A6011.
