TIPO Road/"Manila Expressway"
This first-class expressway will cut 30 minutes off of your trip from Barrio Barretto to Bataan and vice-versa, and bypasses the "zigzag" south of Olongapo. From Barretto, go in the Kalaklan Gate and proceed just past the old McDonalds (follow the signs to Manila), then turn left onto the expressway which exits just north of Dinalupihan. From Bataan, turn onto the expressway at the traffic light north of Dinalupihan and Roosevelt Park. Turn right in front of the old McDonalds and proceed to the Kalaklan Gate. Toll is 20 pesos each way, and well worth it.
