Advisory Group Meeting – March 18, 2004


The following maps were displayed at a meeting of the Improve I-70 Advisory Group in Columbia on March 18, 2004. These maps represent the study team’s recommended preferred alternative for I-70 improvements in the Columbia area.

Additional information is provided here to assist you in understanding the reason for the study team’s recommendation. The Advisory Group Meeting Presentation summarizes the reasonable alternatives that were considered for I-70 and lists the key issues that led to the team’s recommendation. The Impact Summary Table provides the data considered by the team.

A public hearing is expected this fall to gather public input on the reasonable alternatives and the recommended preferred alternative. Details about the hearing will be posted on this Web site once they’re available.

WARNING: The maps below are very large and may be difficult to view, download and print. If you desire a paper copy, please call the hot line at 1-800-590-0066.
