Bonny Serrano Avenue

The Philippine National Police Headquarters on Bonny Serrano Avenue

The four-lane avenue begins as a continuation of Pinaglabanan Street at P. Guevarra Street in the Corazon De Jesus area of San Juan. It proceeds due east and runs through the boundary between barangays Bagong Lipunan ng Crame in Quezon City and West Crame in San Juan, passing through the San Juan Municipal Cemetery before arriving at the northern side of Camp Crame. East of the Epifanio de los Santos Avenue junction, the avenue runs the northern boundary of Camp Aguinaldo with the villages of Socorro (Cubao), San Roque, and Bayanihan, and intersecting with 15th Avenue at Camp Aguinaldo Gate 1. It then intersects with Katipunan Avenue (C-5) via an overpass, passing through barangays Blue Ridge A, Blue Ridge B, and Saint Ignatius before terminating at Eulogio Rodriguez Jr. Avenue (C-5) in Libis near Camp Atienza where it continues as FVR Road all the way to the Marikina–Infanta Highway in Calumpang, Marikina and Santolan, Pasig. This section of the avenue connecting Katipunan and Eulogio Rodriguez Jr. Avenues is designated as a component of Circumferential Road 5 (C-5) and National Route 11 (N11), while its section from EDSA to Katipunan Avenue is designated as the National Route 185 (N185).

The Avenue is a problematic major road that has frequent traffic jams.

Bonny Serrano Avenue was formerly called the Carretera de Santolan (Santolan Road) which ran from the Santolan pumping station on the Mariquina River to El Deposito water reservoir in San Juan del Monte, the main source of water for Manila residents during the Spanish colonial period. It was built around 1901 during the early years of the American colonial period at a cost of $150 (150 pesos).[4] In 1935, the road, also known as the San Juan–Santolan Road, became the location of Camp Murphy, home of the United States Army Philippine Department, and eventually the Philippine Commonwealth Army, which was named after then Governor-General Frank Murphy. The military camp eventually became Camp Aguinaldo and Camp Crame when the Philippines gained independence after World War II. The San Juan–Quezon City segment of Santolan Road was then renamed after Colonel Bonny Merioles Serrano in 1970, three months after the war hero's death.[5]
