The Department of Public Works and Highways (DPWH) has completed the improvement of loading and unloading bays along the Old Zigzag Road. The off–street parking areas or bays are meant for travelers to temporarily park their vehicles and enjoy the view of Pagbilao.
According to OIC-District Engineer Rody A. Angulo , the P15.275 million project under T.A.D. Construction was carried out to improve not only traffic flows but also the travel experience of motorists and local tourists as they journey hours from Manila to Bicol or Visayas and vice versa.
This 2,072 lineal meter road is considered as one of tourist attractions in Quezon Province. It has been known for its steepest path, many tight curves and blind corners. This road is popularly known among visitors especially during Pahiyas festival .
