Highway Strip 58 60

The primary reason for its closure was irreversible infrastructure development. The construction of the Taoyuan Elevated Railway Project (桃園鐵路高架化計畫) required building support pillars and tracks that permanently obstructed the clearway of the highway strip, making it physically impossible for aircraft to land or take off safely.

The site has reverted to being solely a public transportation corridor. It is a regular, heavily used section of Provincial Highway 66. The elevated railway tracks now run parallel to and across the path of the former runway. All specific military markings, communication hookups, and designated aircraft parking areas associated with its former role have been removed. It no longer serves any military function.

Highway Strip 58 60, also known as the Zhongli War-Preparedness Runway (中壢戰備跑道), was one of five strategic highway strips in Taiwan. These strips are a critical component of Taiwan's defense strategy, designed to ensure the Republic of China Air Force (ROCAF) can continue operations if its main airbases are destroyed or disabled in an attack. The strip's most significant historical event occurred on May 15, 2007, during the annual 'Han Kuang 23' military exercise. In a major public demonstration of its capabilities, the ROCAF successfully landed, refueled, re-armed, and launched multiple fighter aircraft from the strip, including US-made F-16s, French-made Mirage 2000-5s, and domestically-produced AIDC F-CK-1 IDF (Indigenous Defense Fighter) jets. This exercise validated the concept and showcased the military's readiness to use public infrastructure for defense.

There are zero plans or prospects for reopening this highway strip. The permanent and obstructive nature of the elevated railway infrastructure makes it impossible to restore the site to its former function as an emergency runway. The Ministry of National Defense has officially written off this location and focuses its readiness drills on the four remaining operational highway strips in Taiwan (Huatan, Minxiong, Rende, and Jiadong).
