The Iowa Department of Transportation (IDOT) will be reconstructing sections of Highway 1 (First Avenue) in Mount Vernon, beginning in 2027.
This two-phase project is expected to affect the following locations on Highway 1 (First Avenue):
2nd Street North to the Union Pacific Railway
2nd Street South to the US Business 30 Roundabout
Residents may see IDOT employees and subcontractor JCG in the area over the coming weeks and days. They may be knocking on doors for those who could be inconvenienced during this time of construction to answer and ask questions. If you see or experience one of these companies, they are known to be in the area by the City of Mount Vernon, and Mount Vernon Lisbon Police Department.
