I-535 and US 53 (Blatnik Bridge), Superior to Duluth, Minn. - Douglas County and St. Louis County, Minn.

Loc​​ation

The John A. Blatnik Bridge carries I-535 and US 53 over the Saint Louis Bay, a tributary of Lake Superior, between Superior, Wis., and Duluth, Minn.

Overvie​w

The Wisconsin and Minnesota Departments of Transportation are planning a future project to replace the bridge and its aging infrastructure, improve safety and accommodate oversize/overweight loads. The bridge currently is load posted for 40 tons.

The structure, built in 1961, is jointly owned and managed by the two agencies. MnDOT is taking the lead on the project. Access MnDOT's Blatnik Bridge project site.

Sched​​ule

Here is the current schedule:

  • 2020-24: Preferred alternative selection and environmental documentation.
  • 2023-25: Preliminary design.
  • 2025-26: Final design.
  • 2025-32: Phased construction, with complete bridge closure for four to five years.

Bicycle/​​Pedestrian Survey

The Minnesota and Wisconsin Departments of Transportation conducted a survey to assist in evaluating the possibility of adding a walking and bicycling path to the Blatnik Bridge as part of future reconstruction or rehabilitation project later this decade.

Public Inv​​olvement

The Minnesota and Wisconsin Departments of Transportation are hosting a public hearing for the project from 5 to 7 p.m. Tuesday, Oct. 3 at the Superior Public Library, 1530 Tower Ave. There will be a presentation of the environmental assessment at 5:30 p.m.
