Naming The Republic of China government named the controlled highway Sun Yat-sen Freeway in honor of Sun Yat-sen, the country's founding father.
National Freeway 1 is a tollway where the amount charged varies by distance traveled, with vehicles being fitted with an electronic tag to facilitate toll calculation; the term "freeway" refers to "free of signal", and not free from charge. There are eleven toll stations on the turnpike.
History The construction began in 1971. The north section between Keelung and Zhongli was completed in 1974, and the entire highway was opened in 1978. Saudi Arabia supported the construction of the highway by providing an interest free loan.
A viaduct on top of the freeway between Xizhi and Wugu was completed in 1997 in order to expand the capacity of the road. An extension of the viaduct south to Yangmei was opened in 2013, at a cost of nearly 3 billion US dollars.
The 2019 Han Kuang Exercise featured takeoff and landing practice by Republic of China Air Force aircraft on the Huatan section of National freeway 1 in Changhua County.
