Work on the 11th Street underpass will pause for the Memorial Day weekend, and crews will resume work, weather permitting, on Tuesday!
A reminder for any weekend travel plans to check 511mn.org for statewide traffic impacts. The 11th Street underpass project is just one of many road construction projects happening across Minnesota. Before you go, check the 511 map to see where you may encounter work zones, detours and more. Always slow down in work zones (even when workers aren't present) and never enter an area blocked by barriers or cones.
Current work and happenings
There have been a few adjustments to the weekly workplans due to the wet conditions from the rain, but crews are still make progress where they can!
Building demolition continues throughout the project area. Silver lining of the rain: it helps to manage the dust at the demo sites. Expect restrictions in the areas immediately surrounding the demolitions—such as no parking or temporary lane closures.
At both railroad crossings on 11th Street, crews continue to prepare each site for shoofly construction. A shoofly is the temporary railroad bypass, which will move trains off of the main track while crews work underneath it to begin building the underpasses. Crews are first building up the area underneath where the shoofly will be constructed, ensuring there's a strong base for the temporary track. They must also make sure the areas properly drain water, so drainage ditches are built too. In early June, railroad crews are scheduled to be on-site to begin constructing the Hillsboro line shoofly, then the KO line once that area is prepped too.
On Eighth Street, north of First Avenue, crews have poured the foundation of the outfall structure in the park, an important part of the storm sewer system, which outfalls to the Red River.
And in the northwest corner of 11th Street and First Avenue, crews have started work on the lift station. Those who live or work near this location can expect to hear loud noises and vibrations for several weeks as crews continue to install sheet piling and shoring.
