TUNNEL 1
Above: A train bound for Grangeville winds through the horseshoe tunnel. There is no US 95 going under bridge 20 as that was completed in 1960. There is also a small wooden bridge that was filled at a later date. Google Earth shows 2 culverts in its place.
Right: Tunnel 1 from Lapwai. A modification to Bridge 20 was constructed to provide room for US95 to pass under.
