St. Clair, Missouri is the only place the line of highest degree of solar occultation (maximum eclipse) crosses Route 66. This will occur August 21, 2017, at 1:17 in the afternoon. The eclipse will last for 2 minutes, 40 seconds, down on the south side within the city limits near the St. Clair High School. The St. Clair Chamber of Commerce will be heading up many events the preceeding weekend, and we're preparing for many of our visitors to stay over until midday Monday to see the show. We're only 52 miles west of the St. Louis Gateway Arch, and you never need to leave the interstate to get here! Come join us in 2017, and check back here as events develop!
