40th Ave West Corridor Project - Study
Overview
The 40th Ave West Corridor Project begins at the Interstate 35 interchange and ends at the railroad crossing located near 9th St for a total distance of 0.8 mile. Both St. Louis County and the City of Duluth own and maintain respective segments of 40th Ave West.
The county segment of 40th Ave West begins at Grand Ave and ends at the railroad crossing located near 9th St. The road name changes at the railroad crossing to Haines Rd. The county road number designation is CSAH 91. The city segment of 40th Ave West begins at the Interstate 35 interchange and ends at Grand Ave. The city road number designation is MSAS 110.
St. Louis County is planning a reconstruction project of the county segment of 40th Ave West in 2026. In preparation for this project, St. Louis County is leading a study to identify improvements that will be included in the future reconstruction project. To ensure continuity along the corridor, the City of Duluth is participating in this study to also identify improvements on the city segment of 40th Ave West. The City of Duluth does not have a construction project currently programmed for 40th Ave West. When funding becomes available, the City of Duluth would then complete the improvements identified in this study.
