Construction progress updates

About this project

  • In 2015 and early 2016 work took place from I-35 to 83rd Avenue West. The original bid for this work is $10,385,411.
  • In 2016 work will take place from 83rd Avenue West to Becks Road. The cost of the work being done in 2016 is $8,830,000. This phase involves reconstruction of drainage, new signal system, a bridge to replace an old box culvert at the Knowlton creek, new sidewalks and 3.29 miles of new bituminous pavement.

Summary of work

  • The pavement in the project area will be removed to the underlying concrete. Then the surface will be repaved with a new bituminous.
  • Driving lanes in the project area will be reduced from 12-feet-wide to 11-feet-wide. This will increase the shoulder width to 6-feet on each side to accommodate bicyclists.
  • Americans with Disabilities Act improvements will be made at intersections.
  • Pedestrian-activated, high-visibility crosswalks will be added in various locations throughout the project to improve pedestrian safety.
  • Sidewalks will be included/improved on both sides of Hwy 23 (Grand Avenue) from I-35 to the end of the urban section.
  • The sidewalk will be extended on the riverside of Grand Avenue to the Pleasant View Mobile Home Park.
  • Additional trail connections will be made from Hwy 23 to the adjacent bike trail.
  • Bike lanes will be added on each side of Hwy 23.
  • Trees will be added (locations are yet to be determined).
  • Bus pull-outs are being added based on discussions with the city of Duluth and the Duluth Transit Authority.
  • Culverts will be replaced or repaired.
  • New curb, gutter and sidewalks will be built on both sides of Hwy 23 from I-35 to approximately 83rd Avenue West.
  • Curb and gutter will be replaced where needed.
  • A few city street connections onto Hwy 23 will be closed due to proximity to other street locations and safety considerations (between the zoo and I-35).
  • A new bridge will be constructed over Kingsbury Creek in front of the zoo.
  • A new bridge will be constructed over Knowlton Creek below Spirit Mountain.
