An Inventory of Future Transit Subsurface Construction
An inventory of future transit (fixed guideway) subsurface construction in the United States and Puerto Rico was undertaken, covering the 1976-1990 time frame. A total of 19 transit constructing authorities in 17 cities were surveyed by questionnaire and on-site visitations. Information was gathered on status, routes, type of construction, costs, geology, environmental factors, and any other unique factors. A total of over 120 miles of planned construction was revealed, expected to cost over $7.5 billion, in the survey time period. However, the total is heavily influenced by planned Washington construction. Among other cities about 30 miles is totally funded; the rest is planned but unfunded. Costs of cut and cover are beginning to approach mined tunnel (except in New York), and environmental considerations often swing the balance.
