Virtis bridge rating

Yesterday I started to learn AASHTO's bridge load rating software "Virtis". I used the program to rate a bridge for an off ramp on I-95 in Providence. So far I have only finished the exterior plate girder in Span #1 of a 3 simple span bridge.

Hopefully soon I will be able to use this program more and with more confidence. In the next three months we have approximately 20 bridges to rate and so far I am currently working on 4 ratings for Rhode Island and a 3 mile long highway foot print reconstruction project in Southbridge, MA.

The drainage which I have been assisting with is almost complete and the calculations are about 130 excel sheets long.

Bridge Rating Inspection

Was out in the field today doing a rating inspection in Providence, Rhode Island. The inspection was for a bridge that carries the off ramp from I-95 South to the Providence Place Mall. The inspection took about 8 hours and around 65 photos were taken to document the conditions.


The bridge consists of 10 spans, 5 of which are built up steel girders with a 64" web and the other 5 are made up of steel box girders with 66" webs. This was my first inspection of a box girder and I was able to open the access port to inspect the interior of the box girders.


I have already started the rating loads for the bridge which include the bridge deck (concrete slab), the parapet and railings.
