At first, I came Notsuto Tunnel (能津登トンネル, notsuto tonneru) east end of Suttsu Town, Cape Shiribetsu (尻別岬, shiribetsu misaki) located border with Rankoshi Town (蘭越町, rankoshi chō). It is in overlapping section of route No.229 and 276 – called Raiden Route (雷電国道, raiden kokudō), current Notsuto Tunnel was completed in 1994. Old one was completed in 1968 at same place. 2 generations ago was been located near tip of cape.
I looked forward to this tunnel because it was drawn in topographic map in the Taisho Period. I see what I can researched about this, it was completed in 1910. It is reputation of being a brilliant born in the Meiji Period.
This is old Tanemae Tunnel. The nameplate, “北海道の道路トンネル“, and “橋梁現況調書” are all said completed in 1963. Design of entrance is same with design of this period R229. But actually, this tunnel is in aerial a photograph taken in 1947. It’s a mystery. If I researched it may became clear, but today I came to see Fukuroma so I didn’t it. If it became clear, I’ll postscript the truth here.2017-01-01Postscript The informations came from comment. Before 1963, it called Arito Tunnel. Its completion year is unknown.
You the tunnel geek may think “Suttsu has more 2 tunnels in southern of urban area”. Unfortunately they are open-cut already. Northern one is in a aerial photograph taken in 1948, isn’t in a aerial photograph taken in 1965. Southern one Tateiwa Tunnel (建岩トンネル, tateiwa tonneru) opened-cut in the past few years. Incidentally it is still drew on GSI map as I write this. 2017-01-01Postscript The informations came from comment. Tateiwa Tunnel was once called Tateiwa No.1 Tunnel. And northern one (名称不明トンネル in the map) called Tateiwa No.2 Tunnel.
