after the 1323.7 meter Hachinoe Oohashi Bridge. Previously the longest bridge in Aomori City was the 993.9 meter Aomori-nishi Bypass overpass which is currently the third longest bridge in Aomori Prefecture.
Emphasis was placed on the aesthetics of the bridge causing the total cost of construction to come to approximately 27 billion yen in comparison to only 8.9 billion yen for the longer Hachinoe Oohashi Bridge. An example of the emphasis on the bridge's appearance is the emblazoning of the letter "A", for "Aomori", at various places such as the base of the bridge and in the shape of the suspension cables. The use of the letter "A" continues on from the nearby Aomori Prefecture Tourism Center “Asupamu”, which is built in the shape of a triangle so that it would look like the initial "A".
The bridge's main tower is made from high strength concrete.
In response to the bridge's long standing problems with ice in the winter months, a plan was made to lay pipes circulating sea water under the road surface to melt the ice. However, due to problems related to the cost and construction time, only one section was able to be completed. As yet there are no indications of when the system will be implemented over the remainder of the bridge as originally planned. Even so, since the installation of the system the number of traffic accidents has drastically decreased.
