This month, the intersection accruing the most feedback was Hall (M-59) at Schoenherr. All callers stated a similar issue: the westbound traffic was experiencing queues, especially during rush hour. The MCDR TOC responded quickly and found that the controllers at the crossovers lost communication to the main intersection. TOC engineers resolved the situation by reestablishing communications from the crossovers to the main intersection.
