Background: Approximately twenty-five years ago, RIDOT stopped using granite curbing as a. standard, with the exception of bridge projects. The primary motivation was cost, as precast. concrete, the replacement, was cheaper to purchase and install.
Longest damage path and duration: The Tri-State Tornado. The longest recorded tornado journey in U.S. history was the Tri-State Tornado of 1925, which traveled almost 220 miles across southeastern Missouri, southern Illinois, and southwestern Indiana during its 3.5-hour life. The average tornado travels about 5 miles.
Across Lake County in Illinois, there was a supercell storm which rapidly produced an EF-1 tornado across Round Lake, Hainesville, Grayslake, and Wildwood, IL. This storm went on to produce a waterspout northeast of North Chicago over Lake Michigan.
