The city of Wauwatosa has suffered adverse effects from the volumes of traffic being diverted onto the city streets by the construction. The number of vehicles on the streets increased by between 63 and 109 percent from what it was before the construction. A 2016 survey conducted by the city found that residents were concerned by the amount of traffic. The higher traffic volumes increased wear on the streets and prevented the city from doing a rebuild of North Avenue. The delay of completion of the north leg has caused concern for city officials as it interfered with plans for work on North Avenue, requiring further postponement of improvements to the deteriorating road. In February 2017, the city council sent a letter to the state legislature requesting that the completion not be delayed.
