The Wisconsin Department of Transportation (WisDOT) retained Ayres to complete the routine and fracture critical inspection of the Cass Street bridge over the Mississippi River in La Crosse. The 2,532-foot bridge carries two lanes of westbound USH 14 and USH 61 traffic to Barron Island near the Minnesota state line. Ayres provided a four-person field team to complete the inspection. The team gathered notes and digital photos and provided a report regarding the bridge’s condition to WisDOT. Ayres used rope access techniques and a lift truck to safely complete the inspection.
