\r\nShimukappu village (\u5360\u51a0\u6751), the center of Hokkaido (\u5317\u6d77\u9053). It has a railway and highway, not inconvenience to traffic. But it is a mountain village like a solitary island by topographic map. Niniu (\u30cb\u30cb\u30a6) area is more like a solitary island, is in this village. Akaiwa tunnel (\u8d64\u5ca9\u30c8\u30f3\u30cd\u30eb) opened in 2007, from Chuo (\u4e2d\u592e) the central of village to here, and occurred old road simultaneously.\r\n

\r\nI started Niniu by bike, and running on 1 lane gravel road. This road looks old road, but I don’t entered the old road yet. Far from it, it is active road and main prefectural road. Number is 136, name is Yubari-Shintoku line (\u5915\u5f35\u65b0\u5f97\u7dda, y\u016bbari shintoku sen). Famus bad prefectural road (\u7370\u9053, d\u014dd\u014d), isn’t it? And it is prefectural road No.610 simultaneously.<\/P>\r\n

\r\nEntrance of old road is here. Active road curve like a crank, I’ll go straight here to enter old road.<\/P>\r\n

\r\nAkaiwa bridge (\u8d64\u5ca9\u6a4b, akaiwa bashi) welcomes me, while 10 seconds after entered. It’s the largest relic of the old road. 60.8 m long, single spaned half-through arch bridge. It has some reason, the orderer is Asahikawa regional forest office (\u65ed\u5ddd\u55b6\u6797\u5c40), notwithstanding prefectural road.<\/P>\r\n

\r\nI heard half-through arch is rare in Hokkaido. Exactly, I’ve never seen.<\/P>\r\n

\r\nThis large bridge is new Akaiwa bridge. I haven’t heard too much, is it curved chord deck truss? New and old roads are piled up like Tokyo expressway. New Akaiwa bridge connect to Akaiwa tunnel at right, and it doesn’t appear until the last.<\/P>\r\n

\r\nThe road after the bridge is good condition that no current no go to ruin.<\/P>\r\n

\r\nLogs pop out from broken road side. The culvert made by logs? Is it forest road?<\/P>\r\n

\r\n

\"20110908085400DSC_1338.JPG\"<\/A>
\r\nIt looks forest road completely. In fact, this road was forest road really.<\/P>\r\n

\r\n

\"20110908092220DSC_1350.JPG\"<\/A>
\r\nThe road between Chuo and Niniu went through Oni pass (\u9b3c\u5ce0, oni t\u014dge), about in 1960, road has changed river side like now. This road is 1 line, but it stringed village road, road of forest owner’s cooperative and road of forest office. Akaiwa bridge ordered by Asahikawa regional forest office because that is a road of forest office. Location that wooden culvert is road of forest owner’s cooperative. Designated to prefectural road was a long time later. So understandable that it looks forest road.<\/P>\r\n

\r\n

\"20110908093824DSC_1358.JPG\"<\/A> \"2011090805.png\"<\/A>
\r\nI can see current road.<\/P>\r\n

\r\nActive Akaiwa tunnel is 2,115 m long. Start work in 2001, propose to finish in 2006. But unexpected design change \u2192 increase the cost \u2192 cheat at office processing \u2192 leak out and stop construction. Finally, somehow tunnel opened on April 9, 2007.<\/P>\r\n
