What % is grade on I-75 east of Chattanooga?

[Illine]

There is a pretty good hill on the east side of Chattanooga on I-75. It's actually between Chattanooga and Cleveland, TN I think. I'd like to know the percent of the grade and how long it is. Is there a book to be purchased with this information?? Thanks!

I am not positive about this but believe that all Interstate highways have no more than 6% grades but the length and altitude determines the difficulty of the grade.  Maybe someone out there knows for sure.
