Route description

From its western terminus at the mainline of National Route 7, the bypass makes its way east to the middle of Aomori. It first meets with a bypass of National Route 280, then it crosses under the tracks of the Hokkaido Shinkansen near Shin-Aomori Station. It is then carried by the Aomori Viaduct (993.8 meters or 3,260 feet) over the Tsugaru Line; this bridge is the third-longest in Aomori Prefecture. The bypass meets the southern terminus of National Route 280 at the east end of the viaduct. It then crosses over the Ōu Main Line and Aoimori Railway Line near Aomori Station meeting its end shortly after at the northern terminus of National Route 4. National Route 4 continues along the same roadway south towards Tokyo.
