Have you passed by Picong Tunnel yet? Located in the town of Picong (formerly Sultan Gumander) in Lanao del Sur, it is the only road tunnel in Mindanao located along the National Highway which connects the cities of Cotabato and Pagadian.

The 60-meter long tunnel was built by the Americans during World War II and up to this day, motorists traveling for the first time along this route will always make a stop and marvel at the tunnel which remains operational for nearly 70 years.

Here’s the map.
