Before the mid-1990s, the route numbers of provincial highways were limited to 1–27. In 1992, planning started for 12 east–west expressways and the West Coast Expressway, indicated by route numbers greater than 60, to ease the congestion in the freeways. Some of these expressways are still under construction. Many of these provincial highways cross through the special municipalities (i.e. Kaohsiung, New Taipei, Taichung, Tainan, Taipei) which are not part of Taiwan Province. Officially, provincial highways are now known as Taiwan highways, but many people still refer to them as provincial roads (). In
