Shaft and Station near Leadville, Colorado for the American Smelting and Refining Company in the amount of $50,000. Lookout Point Dam Highway and Railroad Relocation - Construction of this Willamette River dam necessitated twin highway and railroad relocations. Adjoining contracts totaling $6,113,000 were undertaken by Utah Construction Company in 1949, and completed in May, 1952. All conditions of construction were encountered, from tough rock cuts to treacherous mud slides. At some points it was necessary to strip to a depth in excess of 40 feet to find stable foundations for fills. In many earth cuts, it was necessary to revise slopes as many as three times to take care of the unstable clay material. In spite of these difficulties, the work was completed in time to lay track and reroute trains to permit construction of the dam. Tunnel Demolition - A low cost but interesting and highly successful railroad project was the demolition of a 100 foot tunnel for the Denver & Rio Grande Western Railroad in Gore Canyon, Colorado, in August, 1952. Lifters were drilled at track grade for the entire length of the tunnel. Down holes, spaced over the surface of the rock and line drilled along the cliff side of the tunnel, were loaded and all detonated simultaneously. The single blast totally demolished the tunnel and threw the shot rock clear off the track and into the river. A minimum of excavation and track realignment was thus required, and the busy track was restored to full operation with virtually no service interruption. Labor and supervision were furnished by Utah Construction Co. and the cost of the project was $31,000. Quindio Highway - Columbia National Highways - The work on Columbia's highway system consisted of relocation, widening, some pavement, and general improvement of 343 miles of roads, providing access to the extremely rugged terrain west of Bogata. In addition to the construction, the completed portions of the road had to be maintained in good condition and native crews trained to carry on after completion of the contract. Our original contract signed in 1951, called for some $10,600,000 worth of work. An extension was awarded early in 1954 to continue work through 1956 in the amount of $8,200,000 an indication of the complete satisfaction of the Minister of Public Works.
