Kingston Bypass: Typical cross-section
|Location||National Archives (see all files stored here)|
|File base||Series MT, subseries MT 57|
This is one large plan sheet, rolled up and hermetically sealed in many layers of archival swaddling, that shows the cross section of the Kingston Bypass as originally designed. It's dated 11 April 1923.
It shows the cross-section of the road, including details of the drainage underneath, and indicates the road was designed with one 30-foot carriageway in the middle of broad verges, with footpaths at the very outside. It seems clear that, while only one carriageway was provided, the grading of the whole road width, and the location of drainage gullies, were designed to facilitate later conversion to dual carriageway.
Received wisdom says that the Kingston Bypass was, in reality, opened as a dual carriageway, so it's not clear whether these plans were ever put to use or whether the road was completely redesigned before it was built.
