All Adults C-tran bus passes will now as of September 1st, 2010 will no longer allow Adult All zone access to Portland. That basically means all travel passed Jantzen Beach or the Delta Park - VanPort Maxx station will require additional fare.
The only exception to this rule it seems is the Youth Pass, which will continue to have this attached to it.

I first saw the elimination on the #37 Highway 99 bus tonight while I was riding home. So if you are concerned about this, please contact your local C-tran representatives by phone at 360-695-0123, email off the c-tran website: http://www.c-tran.com
