Tunnel speed limit is 35mph which is a bit slow, and westbound especially it is natural to speed up when exiting the tunnel, but around the bend is where the cops like to sit. I have also seen them sitting on the east side of the tunnels, and even within the ventilation shaft in the long tunnel! Better to set the cruise control at 37 and just take it easy through this area (anyway it’s safer when tourists are about at the dam parking lot entrance).
