Quezon Zigzag Road, or Bitukang Manok, was constructed in 1969 during President Ferdinand Marcos’ administration. Engineers faced the challenge of traversing the rugged slopes of the Sierra Madre mountains to link the southern towns of Quezon to the broader Bicol Region. The road’s tight switchbacks and steep gradients — reminiscent of a chicken’s intestines, hence the local nickname — were a solution to ascending and descending the mountainous terrain without extensive tunneling or earthworks. Over five decades later, it remains a remarkable example of engineering adapting to geography.
