Illinois: Lessons learned from 2017 Solar Eclipse

NOCoE, Illinois DOT

Overview

On August 21, 2017, a total solar eclipse moved west to east across the United States, covering fourteen states. This was a special event that required extensive planning by transportation agencies across the united states. It is important to look back at the 2017 Total Eclipse to see how state and local agencies managed the traffic operations for the traveling public.

The National Operations Center of Excellence will play an active role by being the facilitator in gathering the after action reports, action plan reports, and coordination plan reports. In six years, on April 8, 2024, we will have another total solar eclipse in the U.S. The totality starts at Mexico, crosses U.S. in a diagonal from Texas to Maine, and passes through Canada. NOCoE intends to be the main point of reference for transportation agencies by creating a national repository for the 2024 solar eclipse.

In April 2018, NOCoE hosted a virtual peer exchange where representatives from 10 agencies described their findings and observations about the 2017 solar eclipse in an online web meeting. As a proceeding to the peer exchange, NOCoE has created a dedicated webpage for each state to gather the agency’s lessons learned and findings on the 2017 solar eclipse. The below content includes the information gathered from the state of Illinois.
