How many rows are in the 600 level of the Superdome?

Depends on the section there are more rows on the sidelines than in the endzones. I think some of the sections go 40+

21-43, depending on location

seating chart

It varies. There are more rows between the 35 yard lines than there are in the end zones.

I went to the New Orleans Bowl and went early into the Dome so I could go and check out my seats in the Terrace. Had to request to go check them out as the Terrace was closed. Anyway, sections 611-617 has 43 rows in each section. The good thing was that there are bathrooms behind the sections.
