ODOT District 12 Complex Bridge Inspections (2020-2022)

Strinteg, as sub-consultant to Palmer Engineering, assisted in the routine, in-depth, and fracture critical inspections of the Detroit-Superior, Lorain-Carnegie, and Main Avenue truss bridges in downtown Cleveland, OH between 2020 and 2022. Work included performing industrial climbing techniques and rope access to gain proper hands-on access to fracture critical members, documenting defects, and recommending repairs and retrofits.
