“Work will begin immediately on Farnham, Surrey, by-pass, plans including a ‘fly-over,’ cycle tracks, pedestrian footbridges, and subways,” reported the Portsmouth Evening News in June 1938.
However, construction was halted the following month, with workers diverted to building a nearby army camp. The full two-mile-length of the bypass was not completed until 1947, with the central section being the last to be built. The two outer sections were opened to traffic in February 1940, and it’s likely that a rudimentary cycle track, on one side of the road only, was also usable at this point.
