Unusual combination of precast and cast-in-place concrete used for lining 280-ft long highway tunnel in Mt. Rainier National Park in Washington; precast rings, 2 ft wide by 10 in. thick, were placed first and supported forms for cast-in-place concreting, serving also as form templets; purpose of tunnel lining is to protect traffic from falling rock fragments and from dripping water.
