Show IRK STARTED Oil BINGHAM TOOELE TUNNELJONDAY EXPECTED TO BE COMPLETED WITHIN TWO YEARS, SAY OFFICIALS Expected to be two years in construction, con-struction, excavation on the Bingham-Tooele transportation and drainage tunnel began Monday near the International Smelting and R fining company in Tooele. The long-expected long-expected project will' link Tooele and Bingham with a 23,000 foot tunnel and will cost between $750,-COO $750,-COO and $1,000,000. i An 800 feet long open cut 18 feet wide at the bottom and 24 feet deep at the tunnel entrance will be excavated ex-cavated first under direction of W. E. Ryberg. This is necessary before actual tunneling can begin. The tunnel tun-nel itself will be 12 feet by 12 feet with a four-foot drainage ditch and with a standard gauge railroad track. Ryberg Brothers will grade a spur track 2.6 miles long from the Tooele Valley railroad to the tunnel tun-nel portal. National Tunnel and Mines company, com-pany, formed by the merging of the old Utah-Apex Mines and the Delaware Dela-ware Mining company, which was a subsidiary of the International com pany is in charge of the tunnel construction. con-struction. Save Cost The tunnel will facilitate entrance Into the underground mines as the bore level is from 1,000 to 2,500 feet lower than the present entrance, and will save pumping costs, eliminate elimi-nate hoisting and reduce transportation transpor-tation expense. From 10 to 20 second feet of water wa-ter will be available for industrial and irrigational purposes. Because of this additional water residents at Tooele have been planning water projects. As the floor of the tunnel at Its portal will be 100 feet higher than the street level of Tooele's business district, all but the southwest south-west part of the town will benefit from the new water source. The tunnel grade will be approximately approxi-mately a 17 foot rise per mile from the portal. The tunnel will follow underground in nearly a parallel line the aerial tramway from Bingham to the smelter. Plans for the tunnel provide that it will pass about 300 feet underground and a raise to the surface in the smelter area .will probably pro-bably be driven from the tunnel.
