About the instructor
Michael Craig, PE is Senior Vice President and Southeast Director at Strinteg Corporation, leading bridge inspection and structural engineering across eight states and Puerto Rico. In 27+ years he has inspected over 4,000 structures and completed 3,000+ load ratings and 160+ load tests. He has managed repair and preservation design for complex bridges, including cable-stayed bridges. He holds PE licenses in twelve states, DC and Puerto Rico, SPRAT Level 1, and FAA Part 107 credentials.
Arkansas's bridge program is governed by ARDOT guidelines published in July 2026, among the newest in the region. ARDOT sorts every maintenance need into priority codes from CF (critical finding) through D, treats a load rating below 3 tons as a critical finding, and sets clear criteria for 48-month extended intervals. This one-hour course covers those rules, the history behind Arkansas's scour program, and ARDOT's Bridge Division Policy Guidelines for design and repair.
