The FAA extended to September 22 the public comment period for a draft reevaluation of a proposed centerfield taxiway at Boston Logan International Airport. The FAA deferred its decision on the proposed centerfield taxiway until the taxiway operations north of Runway 15R/33L were assessed. If approved by the FAA, the centerfield taxiway would be a 9,300-foot parallel taxiway between Runway 4L and 4R. According to the FAA, “It would reduce the chance of conflicts between taxiing aircraft and aircraft operating on the runway. The centerfield taxiway would also allow aircraft to taxi to the runway or to the gate more efficiently. Additionally, it would reduce the number of aircraft queuing on existing taxiways, thus reducing delays and air emissions.” The proposed centerfield taxiway is included in a list of actions aimed at improving the airfield’s safety and efficiency and was studied extensively in the Boston-Logan Airside Improvements Planning EIS/EIR (1995 to 2002).
