What is Virtis?
Virtis is a comprehensive bridge rating tool developed by AASHTO. For an agency's bridge inventory it stores detailed bridge descriptions sufficient for structural analysis and performs this analysis.
Why use Virtis?
In an effort to standardize load ratings and improve quality control and oversight, MDOT has purchased a super-site license of AASHTOWare Virtis. This license will allow local agencies and/or their consultants to obtain a license of the software at no cost.
