The latter help traffic using any of the six road bridges west of London Bridge to access the arterial road to and from the south-east quadrant of the orbital motorway, Old Kent Road. Specifically, eastbound traffic from New Kent Road to Old Kent Road can use the flyover; the reverse flow can use the ground-level bypass lane.
A succession of inns, the original name which may have been the documented Bricklayers Arms, served this junction for more than six hundred years. Excavations during the rebuilding of the inn in the 1890s came across very old foundations and a hidden hoard of ancient coins.[3]
Approval of plans for construction of the roundabout and flyover to replace the junction of, and some buildings at, the Old Kent Road (A2), New Kent Road (A201) and Tower Bridge Road (A100) was given by the London County Council in December 1962 with an initial budget cost of £3,510,000 (equivalent to £95,000,000 in 2023). Works were scheduled for 1967.[6] Such construction involved demolition of buildings in all three roads and surrounds as part of a larger regeneration programme. The north end of the Old Kent Road has since the 1750s been bifurcated into Great Dover Street and Tabard Street. These briefly re-combine north of this junction and have taken the greater street's name since the roundabout was built.
The work done made pedestrian underpasses from adjacent roads into the roundabout heart, as London Underground safeguarded a possible extension route of the Bakerloo line from its terminus at Elephant & Castle tube station. This could run along and under the main road under the route of tracks of the demolished station and branch, to join surface services at South Bermondsey station. The roundabout could host a station, akin to Old Street station. Neither remains in the budgeted Bakerloo line extension to Lewisham. The circuitous subways became ugly. In 2013 these were filled in and levelled, becoming wider pavements.
Crossings
Since 2009, pelican crossings exist across New Kent and Old Kent Roads, as pedestrians preferring to cross at-grade were causing accidents.
