The provision of services in densely built up city areas often requires the solving of a large number of varied problems and in most instances involves the responsible authorities in considerable expenditure. Frequent breaking-up of streets and pavements causes inconvenience to the public and is inevitable if services are supplied by the conventional method under road surfaces. The construction of accessible multi-service tunnels appears to provide a solution to the problem and this paper examines the possibility of constructing tunnels under local conditions. The question of cost has been taken into account but due to the need to deal with the subject in a general manner it has not been possible to include detailed estimates of cost. The conclusions reached indicate that no insoluble problems exist and that accessible multi-service tunnels can provide a sound solution to many of the difficulties which arise from the installation of services in densely built-up areas.
