Marikina–Infanta Highway

The Marcos highway starts as a physical continuation of Aurora Boulevard under Katipunan Flyover. The highway slightly curves at the intersection with Andres Bonifacio Avenue connecting the Marikina city proper, then crosses the Marikina River. The Diosdado B. Macapagal Bridge that connects with C-5 merges in front of SM City Marikina. The Manila Line 2 and the Cainta - Marikina subtransmission line of Meralco parallel the highway. The highway makes another slight curve at the approach to Cainta. It soon runs over the Cainta-Marikina boundary, and then goes straight towards the Cainta-Antipolo boundary towards the Masinag Junction with Sumulong Highway wherein it continues on to Cogeo towards the rest of the Rizal Province, Sta. Maria, Laguna to Infanta, Quezon

This highway, also commonly called Marcos Highway is a divided road featuring U-turn slots, and bike lanes. Several establishments, like the Riverbanks Center, SM City Marikina, Ayala Malls Feliz, Robinsons Metro East, Sta. Lucia East Grand Mall, and SM City Masinag are primary landmarks accessible through the road. Meralco subtransmission lines line the Cainta-Masinag segment of the highway up to Santa Maria, Laguna until the Infanta, Quezon Junction

This stretch of the highway is a standard 2-6 lane road divided by lane markings typical of national highways located in the provinces. Road size varies depending on the density of the location as well as the engineering district wherein numerous road widening may occur as determined by the DPWH. The road ends and merges with Famy–Real–Infanta Road (Route 601).

Since 2014 with the implementation of the new route numbering system by the Department of Public Works and Highways (DPWH), it is the component of National Route 59 (N59) of the highway in the Philippine highway network in the Greater Manila Area. From Rizal to Quezon, the road remains unnumbered and identified as a tertiary national road.
