Route 5 & portion of route 12, reconstruction & widening (route 2A to naval magazine/route 12)

The Government of Guam Department of Administration received a $3.4 million project grant from the U.S. Department of Transportation Federal Highway Administration on December 23, 2021 under the Highway Planning and Construction program (CFDA 20.205). The grant will fund the reconstruction and widening of Route 5 from Route 2A to the Naval Magazine facility on Guam, including rehabilitation of the existing roadway to add a minimum of two 11-foot travel lanes in each direction, 4-foot paved shoulders, and 2-foot graded shoulders. The pavement structure will include 1-inch of dense-graded friction course over 3 inches of hot asphalt concrete and 6 inches of cement-treated base on top of 10 inches of aggregate base. Four left turn lanes will be installed at the entrances to Sumay Payless Supermarket, and a double left turn lane and right turn pocket will be provided at the entrances to Naval Facilities Marianas offices. Minor drainage culverts will be installed and best management practices facilities constructed to treat pavement runoff.
