About one student a year would be seriously injured after being hit by a car crossing Buchtel Avenue in the early 80's. In 1983, a young woman was killed by a car and that is when they started seriously discussing closing it. We did close the street in 1981 when we had the May Day celebration there.And it might not have been a campus improvement but at least no one past 1984 ever had to use punch cards to write computer programs ever again.
