 It is a matter of dispute whether the problems were caused by faulty traffic projections, too much development around the interchange or the fact that a "two leg" CFI was built, rather than a full "four leg" CFI.There are some suggestions that a full CFI was not built in order to allow land which would have been used for right-of-way to instead be retained by developers.As of early 2012, the solution to the traffic problems was also a matter of debate.
