40th Ave West - Reconstruction

Overview

St. Louis County is leading a project in 2026 to reconstruct 40th Ave West (CSAH 91) beginning at Grand Ave and ending near the railroad crossing (USDOT #251887W) for a total distance of approximately 0.42 mile. The project design is based on the preliminary layout that was developed from the 40th Ave West Corridor Study which started in September 2023 and completed in June 2024. This reconstruction project is necessary because the pavement section and curb and gutter on 40th Ave West are at the end of their service life. Likewise, the traffic signal system at the intersection of Grand Ave and 40th Ave West is nearing the end of its service life. The City of Duluth will replace city utilities along 40th Ave West in conjunction with the roadway reconstruction.

Key project components include:

1. Remove the traffic signal and construct a mini-roundabout at the intersection of Grand Ave and 40th Ave West.
2. Construct a raised center median along 40th Ave West beginning at Grand Ave and ending at 8th St. Openings in the median will be provided at intersections and alleys.
3. Construct a 10-ft path along the east side and a 6-ft sidewalk along the west side of 40th Ave West. Lighting will be provided for the 10-ft path and intersections.
4. Install an enhanced pedestrian crossing that utilizes a RRFB (pedestrian activated flasher) on 40th Ave West at 6th St.

The roadway reconstruction project in 2026 will stop approximately 100 ft short of the railroad crossing. A separate roadway reconstruction project for this gap is planned for 2027 in conjunction with a project to replace the signals and gates at the railroad crossing and extend the crossing surface. This separate roadway construction project will complete the connection of the 10-ft path on the east side of 40th Ave West to the existing sidewalk on the east side of Haines Rd.
