鎌倉幕府の頃、全国に街道が整備され、旧羽州街道もその一つで、
現在の藤崎町の「唐糸御前史跡公園」の唐糸御前は五代執権
北条時頼の時代なのでおそらく羽州街道を通ってきたと思われます。
しかし、当時の羽州街道は大鰐もしくは石川城のあたりまでで
藤崎までの道のりは記録が無く不明です。
江戸時代初期に常盤村の庄屋を勤めていた三上氏
(現在は弘前市御幸町に住まい)の古文書によると戦国時代までは
常盤村は浪岡北畠氏の領地であったが、津軽為信が津軽を
支配するようになってからは盛んに干拓と新田開発が行われる
ようになり、新たな部落とその部落をつなぐ交通路が整備される様に
なったと記載されているそうです。
また、常盤周辺は十川や浪岡川が頻繁に氾濫するため直線の連絡道路
は構築されず、あちこちに萢や沼地が存在していたそうです。
一方、黒石の市内を通る羽州街道はやはり明暦二年の「津軽信英公」
が黒石にやってきてから徐々に羽州街道を黒石市内に導いたものであり、
それ以前の戦国時代までは高賀野から直接浅瀬石川の橋を超えて
「石名坂館」へ向かう道が有ったと思われます。
現在、その区間は水害修復の耕地整理がなされ、道の形跡はありません
が「石名坂館」周辺にはその街道の痕跡を伺うことが出来ます。

During the Kamakura Shogunate, roads were built all over
 the country, and the old Ushu-Kaido was one of them.
Karaito-Gozen, which is now in the "Karaito-Gozen Historical
 Site Park" in Fujisaki-town, was built during the time
 of the fifth regent, Hojo-Tokiyori, so it is likely
 that he traveled along the Ushu-Kaido.
However, the Ushu-Kaido at that time only went as far as
 Owani or Ishikawa Castle, and there are no records
 of the route to Fujisaki, so it is unknown.
According to an old document from the Mikami-clan
(now living in Miyuki-cho, Hirosaki City),
 who served as the village headman of Tokiwa-mura
 in the Edo period, Tokiwa-mura was the territory
 of the Namioka-Kitabatake-clan until the Sengoku period,
 but after Tsugaru-Tamenobu came to control Tsugaru,
 reclamation and new rice fields were actively developed,
 and it is written that transportation routes connecting
 new villages to each other were developed.
Also, because the Togawa and Namioka rivers frequently
 flooded around Tokiwa, no straight connecting roads were
 built, and there were vineyards and swamps here and there.
Meanwhile, the Ushu-Kaido road that runs through Kuroishi
 was gradually led into the city after Lord Tsugaru-Nobufusa
 arrived in Kuroishi in 1652, and it is believed that up
 until the Sengoku period, there was a road that went
 directly from Kokano to Ishinazaka-Tate, crossing
 the bridge over the Asaseishi-river.
Currently, that section has been reclaimed for farmland
 repairs after flood damage, and there are no traces of the road,
but you can see traces of the road around Ishinazaka-Tate.
