Transportation guru Fred Salvucci said on the Codcast that the proposed West Station is needed now to deal with congestion in Kenmore Square and the Seaport District, not future congestion caused by Harvard University's creation of a new neighborhood in the Allston Landing area.Salvucci’s position is sharply at odds with the views of the Baker administration, which believes current ridership projections for the station are too low to justify building West Station in the near future. Transportation Secretary Stephanie Pollack has said it would be wise to hold off on West Station until around 2040 when Harvard's development plans for the area are more fully formulated.But Salvucci, who served 12 years as state transportation secretary under former governor Michael Dukakis and now teaches at MIT, said the transit connections offered by West Station are needed now to relieve existing congestion on the Massachusetts Turnpike.
