Circumferential Road 4 (C-4), informally known as the C-4 Road, is a network of roads and bridges that all together form the fourth beltway of Metro Manila in the Philippines.[1] Spanning some 27.35km (16.99miles), it connects the cities of Caloocan, Makati, Malabon, Mandaluyong, Navotas, Pasay, Quezon City, and San Juan.
The section of C-4 Road is simply known as such from R-10 at the Bangkulasi Bridge over Tullahan River in Navotas to Paterio Aquino Avenue (Letre Road) at the boundary of Malabon and Caloocan.
After passing Paterio Aquino Avenue (Letre Road), C-4 becomes General San Miguel Street, a four-lane road in Caloocan.
See main article: Samson Road. After passing the junction with Marcelo H. Del Pilar and A. Mabini Streets in Caloocan, C-4 becomes Samson Road. Also called "Caloocan Road" and "Monumento Avenue", it is a main road in Caloocan with four lanes, running up to the roundabout at Monumento, a monument to Andrés Bonifacio.
See main article: EDSA. EDSA is a 10-lane highway that utilizes interchanges and grade separations. EDSA forms the majority portion of the Circumferential Road 4 (C-4) in Metro Manila, passing through the cities of Caloocan, Quezon City, San Juan, Mandaluyong, Makati, and Pasay. The C-4 segment of EDSA starts at Monumento in Caloocan and ends at the intersection with Roxas Boulevard (R-1) in Pasay.
