A 12.9 km (8.0 mi) freeway tunnel passing under Xueshan to link Taipei with Yilan was opened in 2006.
It marked the completion of Taiwan's latest freeway, which was subsequently named the Chiang Wei-shui Freeway in a move that pleased all sides of the political spectrum in Taiwan.

Chiang was featured on a commemorative 10 New Taiwan Dollar coin in 2010.
