Runway 9/27 at Boston Logan International Airport (KBOS) closed today for the start of the first of two 75-day safety construction project phases. The $110 million project, which will be largely funded by the FAA, will install an engineered material arresting system (EMAS) at the end of Runway 27, which abuts Boston Harbor.

“EMAS is a vital safety system at Boston Logan and other airports located near water or ground elevation changes,” said Massport, which operates the airport. Constructed of a lightweight, collapsible material, it is intended to stop an airplane that has overshot the runway. In place at airports around the world, EMAS has prevented scores of serious accidents.
