National Freeway 1 (Taiwan) is the primary north–south freeway on the island of Taiwan, connecting the port city of Keelung with the southern metropolis of Kaohsiung. It serves as the backbone of intercity motor transport alongside Taiwan High Speed Rail and Taiwan Railways Administration routes, linking major urban centers such as Taipei, Taichung, and Tainan while intersecting with other corridors like National Freeway 3 (Taiwan) and National Freeway 5 (Taiwan). The freeway's infrastructure, tolling, and traffic management have been influenced by agencies including the Freeway Bureau and the Ministry of Transportation and Communications (Taiwan).

Route description

The freeway begins near the port and urban district of Keelung and proceeds southwest through the metropolitan Taipei basin, passing near landmarks such as the Taipei 101 skyline, the National Palace Museum, and the administrative center of Zhongzheng District, Taipei. Continuing through Taoyuan, it skirts the Taoyuan International Airport access corridors before entering the central plains around Hsinchu, where it parallels corridors used by the Science and Technology Park and industrial facilities tied to companies like TSMC and Foxconn. From Miaoli and Taichung, the freeway traverses an agricultural plain adjacent to the Zhonggang River and approaches the coastal plain near Chiayi, then proceeds past Tainan into the metropolitan area of Kaohsiung close to the Port of Kaohsiung and the industrial zones of Zuoying District.

History

Planning for the north–south motorway corridor emerged during the 1960s amid development projects promoted by leaders such as Chiang Kai-shek and institutions including the Economic Planning Council. Construction milestones tied to contractors from firms influenced by foreign advisers occurred in the 1970s, with formal opening phases in 1978 supported by the Ministry of Transportation and Communications (Taiwan), the Freeway Bureau, and municipal governments of Taipei City and Kaohsiung City. Subsequent upgrades paralleled national infrastructure initiatives like the expansion of Sun Yat-sen Freeway capacities and integration with the Taipei Mass Rapid Transit and Kaohsiung Mass Rapid Transit networks. Major modernization projects in the 1990s and 2000s addressed capacity demands associated with economic shifts tied to the Asian financial crisis aftermath, regional trade through the Port of Kaohsiung, and the growth of technology clusters in Hsinchu Science Park.

Interchanges and exits

The freeway's interchange network links to urban expressways and national routes, including connections to National Freeway 3 (Taiwan), the Old Taipei Highway corridors, and provincial routes serving New Taipei City districts like Banqiao and Sanchong District. Major interchanges include those serving Taoyuan International Airport, the Hsinchu Interchange near the Hsinchu Science Park, the Taichung Interchange adjacent to Taichung Port, and southern nodes near Tainan Station and Zuoying. The distribution of exits coordinates with municipal planning authorities such as the Taoyuan City Government, Taichung City Government, and Kaohsiung City Government, and with transportation planning agencies like the Urban and Rural Development Commission.

Services and facilities

Service areas and rest stops along the route are operated by contractors and municipal authorities, offering fuel from brands known to supply Taiwanese markets and retail amenities akin to those at Taipei Main Station concourses. Facilities include parking, restrooms, food courts, convenience stores similar to those in Ximending, EV charging stations aligned with providers servicing regions including Taoyuan and Tainan, and emergency telephones tied into the Freeway Bureau control centers. Adjacent park-and-ride and logistics hubs coordinate with freight operators serving the Port of Kaohsiung and distribution centers near Taichung and Hsinchu.

Traffic volume and tolling

Traffic volumes reflect peak commuter flows into Taipei and Kaohsiung with heavy freight movements to and from ports like Keelung and Kaohsiung Port, and commuter transfer patterns that intersect with Taiwan High Speed Rail schedules. Tolling was historically managed via toll booths administered by the National Freeway Bureau and later transitioned toward electronic toll collection systems interoperable with transit payment schemes used at Taipei Metro and regional bus operators such as Kuo-Kuang Motor Transport. Traffic monitoring integrates ITS technologies used by agencies including the Freeway Bureau and the Ministry of Transportation and Communications (Taiwan) to manage congestion and incident response.

Incidents and maintenance

The freeway has experienced incidents ranging from multi-vehicle collisions near urban interchanges to weather-related disruptions from typhoons impacting sections adjacent to the western coastal plain; response and recovery operations have involved the National Fire Agency (Taiwan), local police forces of New Taipei City Police Department and Kaohsiung City Police Department, and emergency medical services coordinated with hospitals such as National Taiwan University Hospital and Kaohsiung Medical University Chung-Ho Memorial Hospital. Maintenance programs have included pavement rehabilitation projects contracted through firms influenced by standards from organizations like the International Road Federation and coordinated with national disaster preparedness plans after events such as Typhoon Morakot and strong seismic events monitored by the Central Weather Administration (Taiwan).

Future developments and expansions

Planned improvements focus on capacity enhancement, safety upgrades, and integration with clean-energy initiatives promoted by agencies such as the Ministry of Economic Affairs and the Environmental Protection Administration (Taiwan). Projects under consideration include interchange reconstructions near growing urban zones like Taoyuan and Taichung, EV infrastructure expansion in collaboration with suppliers serving Taiwan Semiconductor Manufacturing Company facilities, and resilience upgrades informed by research from institutions like Academia Sinica and engineering departments at National Taiwan University and National Cheng Kung University. Coordination with national transportation strategies aims to balance freight links to the Port of Kaohsiung and passenger mobility tied to Taiwan High Speed Rail and regional transit investments.
