From this story in the Pueblo (CO) Chieftain:
The U.S. Bureau of Land Management on Thursday released the final environmental impact statement for New York artist Christo's Over The River project, paving the way for the plan to proceed if final approval comes this fall. After 2 1/2 years of study, the approved form is much how Christo envisioned the grand-scale artwork. It will allow for the suspension of eight silvery, luminous fabric panel segments totaling 5.9 miles over portions of the Arkansas River between Salida and Canon City. _Christo has projected a $50 million cost to build the grand art display. The final report projects that Over the River will generate $121 million in economic impact and draw 400,000 visitors during construction and display. The Arkansas Headwaters Recreation Area, from Leadville to Pueblo, attracts more than 740,000 visitors in a normal year. Construction is anticipated to begin next year and culminate with a two-week display in August 2014.
