GLENWOOD CANYON, Colo. (KKCO) -- The Glenwood Canyon stretch of the I-70-- an engineering feat -- celebrates its 20th anniversary on Sunday.
The I-70 cooridor 13 years and nearly $500 million to construct. Still, the elevated highway remains a vital piece of transportation, a popular attraction and an important link to recreation.
During the planning stages, a citizen’s advisory group greatly influenced the design of the canyon project. Many art techniques were used for the rock excavation, traffic handling and re-vegetation. The project received the 1994 ASCE Outstanding Civil Engineering Achievement award, as well as many more than 30 other awards and recognitions.
Around 50 project engineers, consultants, designers and many others gathered at the historic Hotel Colorado in Glenwood to celebrate the 20 years. There they enjoyed a day of cycling along the canyon bike path they constructed.
The Glenwood Canyon project involved 300 engineers and other crew members. There were 40 bridges, 15 miles of retaining walls, two 4,000-foot-long tunnels, 150,000 new trees and shrubs planted, 30,000 tons of structural and reinforcing steel, and 810,000 tons of concrete put down.
