Pedestrians crossing Putney High Street, London

NOTES: This concrete block crossing was one of several types constructed by local boroughs complying with the Ministry of Transport's directive that demarcation should be by a lane of studs terminated by a Belisha beacon. Such crossings were superseded by the zebra crossing which, having been experimented on a 1000 sites throughout the UK in 1949, was introduced into law in 1951.
