Details are given of the Seattle transit tunnel scheme which has been chosen by the Municipality of Metropolitan Seattle (metro) to solve the traffic congestion problem of the central area of Seattle. Central Seattle's employment population is expected to grow to 150,000 by 1990 and transit is expected to absorb the added commuter load. Metro has steadily increased the number of buses in response to growing demand and now channels approx 500 buses onto congested streets during each peak-use hour. The scheme, said to be an innovative and cost effective solution to Seattle's problem, is for a 1.3 mile long tunnel for electric buses through the heart of the city. The tunnel project will provide shorter commuting time and a more reliable service to transit patrons while maintaining an efficient transit system and relieving downtown Seattle congestion. The scheme is less expensive than a new rail system and will provide for transit system capacity past the year 2000. Construction on bored sections could begin by March 1986 with the tunnel opening by 1990. (TRRL)
