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 and San Juan–Santolan Pumping Station Road,^[5] 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 road was then renamed after Colonel Bonny Merioles Serrano in 1970, three months after the war hero's death.^[6]
