Possibilities for reducing land used for urban transportation in central city core by providing ample automotive access with deep underground tunnels and parking areas are examined; cost of conventional urban highways built through densely populated areas is described in terms of construction costs, right-of-way acquisition costs, and selected operating expenditures; recommendations are given for study of underground highway concept and developments of prototype machines capable of rapid excavation of vehicular tunnels under most rock conditions.
