Tenzan Highway

The Tenzan Highway is a cross-border highway between Akitsukuni and Elwha, linking the cities of Hiwi and Ishimachi. Passing through the Skykomish Valley, the Tenzan Highway is the only major highway linking both nations. On the Akitsukunese side, it also services several smaller settlements and towns in the vicinity of the Tenzan foothills before arriving at Ishimachi.

A landmark cooperative project, the Tenzan Highway was built in 1993 to reinforce the older network of roads and poorly-maintained highways that served the area and revitalise the economic development of the war-affected area, as well as to display reconciliation between the two nations after the 1987 Mountain War. The Akitsukunese and Elwhan road networks were not connected before the construction of the highway. With the completion of the highway, tourism and road trade in the region has improved.

However, political rivalries and continued cold relations between the nations ensures that the border controls between the nations continues to be highly strict, resulting in long waiting times at the border crossing.
