Depends on what part of the CBBT you are referring to. The 3rd/4th are closer than the 1/2nd just because of the way the bridge curves. Anyway I used to make that run all the time from the boatel. If I recall it was about 36 miles or thereabouts from the hole in the wall. On a good day you can make it in a little over an hour, probably an hour on a really good day.
