referendum, citing fears of increased taxes and congestion. A May 1977 state bill prohibiting extension into Arlington was vetoed by then-governor Michael Dukakis. The Environmental Impact Statement, released in August 1977, primarily evaluated the Arlington Heights terminus but also provided for a shorter Alewife extension. By the time the northwest extension began construction in 1978, opposition in Arlington and reductions in federal funding had caused the MBTA to choose the shorter Alewife alternative. The Red Line was extended temporarily to Harvard–Brattle over former yard and storage tracks on March 24, 1979. This allowed for bus transfers to be provided. The Harvard bus tunnel was closed temporarily at the time. On January 31, 1981, the original Harvard station was permanently closed, as its demolition was required. To replace it, a temporary station at Harvard–Holyoke was built across the tracks. The two temporary stations were closed on September 2, 1983 in preparation for the opening of the new Harvard station. On September 6, 1983, the new station at Harvard opened, with trains changing direction at Davis Square without carrying passengers. Eliot Yard was demolished; Harvard Kennedy School now sits inside its retaining walls. The line was extended to Davis with a station at Porter on December 8, 1984. The line was extended to its current terminus at Alewife on March 30, 1985. At the time, all off-peak trains terminated there, but due to the incomplete construction of a yard at Alewife, only Ashmont trains ran to Alewife during rush hours. Davis was the terminal for rush hour Braintree trains. These trains were finally extended to Alewife during rush hours on December 26, 1985, with the completion of the yard at Alewife. During the expansion, the MBTA pioneered an investment in the "Arts on the Line" public art program. Fill from the tunnel excavation was used to create Danehy Park on the former site of the Cambridge City Dump, and to restore Russell Field in Cambridge and Magnolia Park in Arlington. Station renovations A 1979 renovation of added two elevators, making it the first accessible station on the Red Line. In the early 1980s, the MBTA began extending platforms for six-car trains: and in 1981, in 1982, and and in the mid-1980s. (The Northwest and South Shore extensions had been built for longer trains, while had been modified in 1970.) In the mid-1980s, the MBTA spent $80 million to extend the platforms of
