Guam - Construction along Andersen Air Force Base's Arc Light Blvd. will result in a closure of the base front gate this weekend. AAFB officials report all traffic will be diverted through the Santa Rosa gate. The visitor's center will also be closed from 2am to 5am on both Saturday and Sunday, and services at the facility will not be transferred to the back gate. Those requiring a visitor's pass are asked to plan accordingly. Commercial traffic coordinated prior to the closure will be the only exception during this period. The main AAFB gate is scheduled to close May 5 and 6 from 1am Saturday to 5pm Sunday.
