Kumanichi reported on the tunnel under construction between Ozu and Aso to replace that crumbled section of Rt. 57. Apparently, building a tunnel is similar to cooking in that the most efficient way to proceed is not necessarily how the food comes out but different in that you also have to excavate evacuation routes (something perhaps recommended for some places I’ve eaten). Anyway, they’re proceeding at what for boring is a lickety-split pace, with over 10% of the entire 3.7km length complete across various sections. The tunnel is expected to open in 2020. - William
