Many residents opposed the plans made by WisDOT for arterial street improvements prior to the interchange reconstruction. Plans included expanding Blue Mound Road in Wauwatosa to ten lanes, including three through lanes and three left turn lanes. This would eliminate on street parking, which would present challenges to local businesses. The intersecting Mayfair Road would be increased to 11 lanes. Already considered one of the busiest in the state, the intersection would see a major increase in traffic volume. Area residents feared the increased traffic would create safety hazards and overflow into the surrounding neighborhoods. Similar expansion plans on Wisconsin Avenue would cut into residential properties along the street.
