今回は旧羽州街道の黒石市内にある部分の最終ルートです。
このルートは江戸時代になってから確立されたと思われます。
それ以前は高賀野から石名坂館へ川をわたって牡丹平に抜けて
そこから長坂を通って、上十川へ渡り、赤坂を経て三島、高舘と
通っていたと思われます。ただ、江戸時代に入って黒石に
弘前津軽藩の分家(津軽信英公)が新たに館を設けて街づくりを
行ったことにより、商人町が形成され、宿場となって賑わいが
出来たため、自然と高賀野から浅瀬石村を経由して長崎の
河岸段丘の坂を上って山形町、前町、中町、浜町という
交通ルートが新しく確立されて行った様です。
この後竹鼻集落を境にして現在の青森市内、本郷に入ります。

This is the final route of the old Ushu-Kaido road 
in Kuroishi city.This route is thought to have been
 established in the Edo period.
Before that, it was thought to have gone from "kokano"
to "Ishinazakadate", crossed the river, passed through 
"Botandaira", passed through "Nagasaka", 
crossed the "Kamitogawa", passed through "Akasaka", 
and went to "Mishima" and "Takadate".  However, 
when the Edo-period began, a branch of the Hirosaki-
Tsugaru-clan (Lord Tsugaru-Nobufusa) built a new house
in Kuroishi and started to develop the town, 
forming a merchant town and becoming a bustling post town.
Naturally, a new transportation route was established 
from Kokano via Aseishimura, up the slope of 
Nagasaki's river terrace, through Yamagata-machi, Mae-machi,
Naka-machi, and Hama-machi.
After this, the road crosses the Takehana settlement
and enters Hongo, which is now part of Aomori city.
