1918 Final work on shoulders and ditches is finished on Colorado's first completed Federal-aid project (3.95 miles of the Colorado Springs Highway, part of the Great North and South Highway). The project, which begins at Denver's southern limit, has a 16-foot concrete pavement, with an average thickness of 5 3/4 inches and 4-foot gravel or sand shoulders on each side. Work on the concrete pavement began July 19 and was completed November 5. Total cost is $80,703.10, with a Federal share of $37,198.49 (46.1 percent of the combined cost of construction and engineering). According to the last traffic census, the old road carried 1,200 vehicles a day, considered "very heavy."
1979 The second, eastbound bore of the I-70/Eisenhower Memorial Tunnel in Colorado opens. (See March 8, 1973.) The contract for the second bore was signed on August 11, 1975; the tunnel was "holed through" on August 17, 1978. The Colorado Department of Highways developed the project in cooperation with FHWA's Division Office. Division Structural Engineer Larry Lutz is FHWA's representative on the project.
