Gas Stations Along the Route (in travel order, from OpenStreetMap)
- ⛽ CPCapprox. 37.5K /
Distances between stations are approximate values calculated along the route geometry (only gas stations within 500 m of the route are counted). OpenStreetMap is edited by volunteers, so stations may be missing or closed; check business hours on site. On remote stretches, plan your fuel carefully rather than relying on this data alone.
Elevation Profile (Shiding ⇄ Toucheng; highest approx. 555 m, lowest approx. 25 m)

The horizontal axis is distance along the route; the vertical axis is elevation (the height scale is exaggerated, so slopes look steeper than they are). Dots mark cameras (tappable) and stations. Elevation is estimated from AWS terrain data; tunnel and bridge sections are interpolated between their ends, so errors of several tens of meters are possible. For planning reference only.
Map
After opening the map, use the buttons to toggle layers. Dot colors follow the estimated road surface; tap a dot to see weather and the camera. Rainfall, temperature, and wind are from the nearest station to each point; road surface moisture is an estimate. Gas stations, stores, restaurants, and attractions come from OpenStreetMap and only include places near the route; check business hours and conditions on site. For closures and traffic control, rely on the Highway Bureau live traffic information ↗. The route line runs from Shiding to Toucheng, joined from the OpenStreetMap road network.

Beiyi Highway is the mountain section of Provincial Highway 9 between Xindian and Toucheng/Jiaoxi in Yilan. Pinglin is a common stop for riders. The stretch from Pinglin toward Yilan is known as the “Nine Bends and Eighteen Turns,” with closely spaced curves and steep grades. Weekend traffic includes many motorcycles.
Highlights & Attractions
A favorite motorcycle destination connecting Taipei and Yilan, known for its winding road. Nearby sights include Crocodile Island in Shiding, the Pinglin Tea Museum, and Shipai County Boundary Park.
Typical Weather
Fog is common between Pinglin and the county boundary. Northeast monsoon conditions bring winter drizzle, leaving parts of the road damp or slippery for long periods even after the rain stops.
Riding Tips
There are multiple average-speed enforcement sections, mobile speed cameras, and roadside photographers. Blind curves are frequent. Never cross double yellow lines, and watch for oncoming vehicles drifting wide through curves.
