Duluth´s Lakewalk to reopen by Grandma’s Marathon

Duluth has finished reconstructing the boardwalk portion of its popular Lakewalk, but people should not be tempted to use the fenced-off stretch of path running toward Canal Park quite yet, warned Mike LeBeau, construction project manager.

“That section of the Lakewalk remains a construction site that’s closed to the public. We need people to stay off it and stay safe,” he said.

Favorable weather has enabled crews to make quicker progress on the project than anticipated, and LeBeau referred to the work as “probably about 95% done.” But he said grading, landscaping and the installation of a paved asphalt path for wheeled traffic still awaits.

LeBeau said the project is fully on track to meet the goal of reopening before Grandma’s Marathon, June 19.

The Lakewalk was badly damaged by back-to-back storms that undermined the path, leaving holes in it up to 3 feet deep after an October 2018 battering.

Since then, more than $16 million has been invested in efforts to bolster the shoreline and rebuild a path through Canal Park that would be less susceptible to future damage. A combination of state, federal and local funding have all been brought to bear on this Phase 3 of the restoration project.

To lessen the pounding the Lakewalk receives from storms, LeBeau described the revetment that has been installed, beginning with 10- to 12-ton toe stones, many of them the size of an automobile, that were dug into the lake bottom roughly 30 feet from the water’s edge. These base reinforcements then were backfilled toward shore with what LeBeau described as filter stone and core stone topped by two layers of armor stone.

Finally, an 18-inch-thick concrete wall was installed, with the top lip of that structure sitting about 2 feet above the surface of the newly constructed Lakewalk.

The Lakewalk, too, has been elevated about 3 feet above its original level.

“We know that waves will still break over the top in really big storms. But it’s a matter of protecting the Lakewalk, so the wave energy won’t undermine it again,” LeBeau said.

In addition to building a more resilient Lakewalk, the city is significantly enlarging it. The original 6-foot width of the boardwalk will grow to 10 feet, and the paved trail will go from 7 to 12 feet wide.

LeBeau explained that the city enlarged the Lakewalk in recognition of its current popularity and in anticipation that the volume of users it accommodates will continue to grow.
