History
The first phase of the road project, a 14-kilometer segment between NLEX and Plaridel, was opened in March 2012 and funded through Japan's official development assistance.[4]
During the administration of President Benigno Aquino III, the road was initially planned to be a toll road named Plaridel Bypass Toll Road.[5] However, it was revised to become an untolled road, which was later known as the Plaridel–San Rafael Bypass Road Project.[6]
Construction of the road began in 2016, funded by a loan agreement with the Japan International Cooperation Agency. On April 30, 2018, Arterial Road Bypass Project Phase II was inaugurated.[7] followed by the 10-kilometer (6.2 mi) Phase 2 section from Balagtas to Bustos on May 5.[8]
