Six-lane tunnel sits on sacks of grout
Tingstad Tunnel under Gotha River in Gothenburg, Sweden, is first subaqueous tunnel with three-lane roadways; full width of structure is 98 ft built in five sections by sunken-tube method; over 1000 wood piles were driven more than 70 ft deep to support tunnel in clay; to transfer tunnel loads to piles, nylon sacks pumped full of grout to form-fit between tunnel bottom and tops of piles were inflated to about 7 in. thick between piles and tunnel bottom.
