PLANNING SUBWAYS BY TUNNEL OR CUT-AND-COVER. SOME COST- BENEFIT COMPARISONS

The largest single cost for any new transit system is construction, accounting for up to 70 percent of the total system cost. But intangible social costs, borne by the affected neighborhood community, may add as much as 25 percent to the total system cost. When these intangibles are taken into account in terms of loss of local economy, decrease of social activities, and general community disruption, high speed and deep tunneling methods become more competitive with cut and cover construction.
