2020 City Construction Projects Impacting Traffic

The 2020 construction season will include a number of projects that will impact traffic (vehicular and pedestrian) throughout Dubuque. These infrastructure improvement projects may involve some short-term inconveniences for residents and businesses, but they are significant community investments that will provide long-term benefits. Additional projects will be conducted during the construction season, but are not expected to impact traffic. 


The City recognizes businesses located in work zones have special needs. It’s critical that customers have access to businesses and that they continue to visit them, regardless of any road work inconveniences. The Road Construction Toolkit for Businesses is offered as a resource for businesses. It outlines what the City provides before and during road construction projects, ideas about what businesses can do to proactively prepare for construction projects in their area, and other helpful information such as the construction noise ordinance, dust control measures, parking and transportation alternatives, and temporary sign permits. Through communication and cooperation, businesses can thrive when road construction is in the area.

CodeRED Emergency Notification System

The City of Dubuque has instituted the CodeRED Emergency Notification System, a high-speed telephone communication service for emergency notifications and other important messages. This system allows local officials to telephone all or targeted areas of the city or county in case of an emergency situation that requires immediate action.

Odd/Event Snow Route Alerts

CodeRED will also be used to notify residents who live on Dubuque’s snow routes when the City’s odd/even snow route policy is implemented. Click here to learn more about the odd/even snow route policy and alerts.
