Southwest Region Highway Projects and Studies

WisDOT COVID-19 information

WisDOT continues to monitor the public health crisis as it applies to essential highway maintenance and construction projects. Workers who support the construction of critical or strategic infrastructure are considered essential by the U.S. Department of Homeland Security.
Workers are expected to continue to take precautions against the spread of COVID-19 at the office and job site.

Monitor the Wisconsin Department of Health for latest information and guidance.

With our partners in industry, we will strive to keep this construction season on schedule.
