Final Phase of Northwest Passage Skywalk Construction

Published: Expires: 9/12/2015

Closure of Lake Avenue on-ramp to southbound I-35 and the frontage road alongside southbound I-35.

DULUTH, MINNESOTA (September 4, 2015) – As reconstruction of the Northwest Passage Skywalk enters the final stage, a lane shift on Southbound I-35 will take place Tuesday, September 8, 2015 at 6:00 a.m. The on-ramp from Lake Avenue along with the right lane on Southbound I-35 will be closed at that time. The left lane on Southbound I-35 will be open for thru traffic.  Additionally, the frontage road alongside Southbound I-35 from 1st Avenue West to 5th Avenue West is currently closed. These closures are expected to last three weeks or less.

The detour routing during these closures are as follows: Traffic coming from downtown Duluth or Canal Park will access Southbound I-35 via the 5th Avenue West on-ramp rather than the Lake Avenue on-ramp. Traffic from Canal Park will be routed via Railroad Street and 5th Avenue West.  Traffic from other areas will travel to 5th Avenue West to re-enter the freeway via the on-ramp.

The Duluth Transit Authority’s (DTA) DECC & Downtown Shuttle Bus (Route 22) will continue to run on Railroad Street during weekdays with the main DECC stop located just below the Northwest Passage.

This press release contains the most current information regarding the project’s timeline. Progress reports with timeline updates will be provided on a weekly basis. The most current closure/detour maps are available at
