After completion of an FAA-approved redesign and reconstruction of taxiway Alpha-2, Van Nuys (Calif.) Airport officials commissioned parallel taxiways Alpha-2 and Alpha-3 last week. Both A2 and A3 are approximately 50 feet wide by 1,300 feet long and are installed with unidirectional centerline lighting to enhance night operations. The airport said the project increases operational safety by reconfiguring A2 into two parallel taxiways, permitting traffic in only one direction on each lane.
