Along the stretch of highway between Boston Bar and Yale are
7 tunnels, built between 1957 and 1964, as part of the Trans-Canada Highway. From South to North the tunnels are: Yale (1963), Saddle Rock (1958), Sailor Bar (1959), Alexandra (1964), Hell's Gate(1960), Ferrabee (1964) and China Bar (1961).
Following that order, driving from south to north, our second Benchmark is 66C110, monumented in 1966 in the face of the east end of Yale Tunnel. It's in the centre of the north face, right at ground level, lower than indicated in the NRCAN report.
There's not really a safe place to park at the east end of the tunnel. Better to park west of the tunnel and walk through on the sidewalk along the north side of the tunnel.
