This has been in the wind for years. Beacon is a very popular HS on the upper west side that takes kids from all over the city. They have been cramped into a building on W. 61 St. for years. School officials plan to move Beacon to new construction on the north side of W. 43rd St. that is currently used by the NY Public Library for document storage. It will be a 3 year long construction project. The new home for the school will expand capacity to 1400 students.
