Route description

N305 was constructed by the United States Government when the Olongapo was a Naval Reservation. U.S. Navy personnel used the route to provide access to Manila while the U.S. Naval Base Subic Bay existed in Olongapo.

Magsaysay Drive

N305 starts at the Magsaysay Bridge as its southern terminus, a pedestrian walkway that used to be a roadway for vehicles, then provided access to the Subic Bay Freeport Zone until 2011 when SM City Olongapo was built. The route is entirely a one-way road for northbound vehicles. Magsaysay Drive ends at the Friendship Rotunda, a roundabout intersection that was built in the 1970s.

Rizal Avenue

Going further north, N305 continues the route after the Friendship Rotunda, as Rizal Avenue. the Bajac-Bajac Bridge also crosses the route. N305 terminates north at the Ulo ng Apo roundabout – intersecting with other major roads of Jose Abad Santos Avenue (N3) and Olongapo–Bugallon Road (N306).


N305 was maintained by the City Government of Olongapo and the Department of Public Works and Highways.


The route was equipped with CCTV camera, traffic cones and proper traffic signage to provide safety features and guide direction for motorist. the whole route has assigned traffic personnel enforced by Office of the Traffic Management and Public Safety.
