Tagudin–Cervantes–Sabangan Road (also known as Mountain Province–Ilocos Sur Road or Bessang Pass), signed as National Route 205 (N205) of the Philippine highway network, is a 98-kilometer (61 mi) national secondary road in the Philippines that connects between the provinces of Ilocos Sur[1] and Mountain Province.

[2] The road starts at the junction of Halsema Highway as its eastern terminus.

Along the way, it provides an access to the Bessang Pass Natural Monument, which is located at the highest elevation of the road before going to the lowlands of the province.

From the World War II memorial marker in Tagudin, the road traverses Suyo and Cervantes in Ilocos Sur.

The road continues to Sabangan, where Halsema Highway is.
