  • Load Rating for all superstructure types
Ohio Bridge News

Did you know?
All Ohio counties must have their inventory of bridges load rated in Load Factor Design (LFD) to determine the structures safe load carrying capacity. Also, beginning in 2010, FHWA will require all new bridges be load rated using Load and Resistance Factor Rating.

We are Here to Help!
WD Transportation can provide load ratings for all superstructure types including steel trusses in an efficient and cost-effective manner!
