There's the strong possibility that OCTA hasn't arrived at a means of revenue apportionment for drivers directly accessing one tolled system (the 241/261/133 South County tollways) and the other (the 91 dedicated commuter lanes). It certainly took them long enough to make a deal with Riverside County to extend the lanes into Corona and I-15; at this point -- since two county agencies are now involved with the administration of the 91 toll lanes, adding an additional variant on the existing bi-jurisdiction formula is something OCTA and their Riverside counterparts are intending to postpone as long as they can -- or until an interagency deal that puts extra driver $$ into their working pockets can be cobbled together. Knowing OCTA and their political handlers, it won't be just the possibility of congestion that is stalling the direct-connection process -- it's who gets what in terms of income-sharing; once that's sorted out, expect a good deal of backtracking about the congestion concerns.
