New Hwy 210 Bridge completed and open
The new Hwy 210 Bridge is open and may be accessed from Jay Cooke State Park. Motorists may drive across the new bridge and travel as far as Oldenburg Point, where they are required to turn around.
Highway 210 will remain closed from Oldenburg Point to Jay Cooke Road until Minnesota Power completes the construction work they are doing in the Forbay Lake area.
Public meeting held August 22
A public meeting was held August 22 to discuss the future of Hwy 210 through Jay Cooke State Park
The meeting provided an opportunity for area residents, visitors, local leaders and other citizens to offer input and express any concerns about the roadway that has been closed since the June 2012 flood. The input will be used to help guide potential investment in road reconstruction in the Jay Cooke Park area.
For information about future meetings please contact Andy Hubley, Regional Planning Division, Arrowhead Regional Development Commission, at 218-529-7512 or by email to firstname.lastname@example.org

Week of November 4
Work on the new Highway 210 Bridge is finished. Hwy 210 will remain closed at the Jay Cooke State Park Headquarters until Minnesota Power completes the construction work they are doing in the Forbay Lake area. This work is expected to be completed in late-November or early-December.
Week of October 21
The new Highway 210 Bridge is expected to be completed in early-November.
Week of September 23
The contractor continued deck forming and rebar placement. Roadway grading resumed on the east approach to the bridge. The bridge deck concrete was placed Friday, Sept. 27.
Week of September 16
The contractor continued forming the bridge deck. Placement of the bridge deck reinforcement began.
Grading operations at the west approach to the bridge included placing the select granular and aggregate base for the roadway construction.
Week of September 9
Forming for the bridge deck continued, placement of the steel reinforcement began. Slopes were graded between the bridge abutments and the piers.
Week of September 3
The concrete beams were installed in the last two spans. The contractor formed the bridge deck in the first two spans from the west. The east abutment wing walls were formed and poured.
Week of August 26
The east abutment was formed and poured. Precast concrete beams were delivered and placed in the first two spans from the west or spans 0 and 1.
Week of August 19
The piling was driven for the east abutment. The concrete footing for the east abutment was poured.
Week of August 12
Pier 2 was completed. The piling for the east abutment was installed.
Bridge beams will be placed the week of August 26. Once that has been completed, the bridge decking work will follow.
The grading operation will resume the week of September 3.
Week of August 5
Pier 1 was completed. The Pier 2 stem was constructed.
Week of July 29
Work continued on the bridge substructures. The pier cap for Pier 0 was formed and the concrete was placed. The pier column form was removed from Pier 0, moved to Pier 1 footing, reassembled and the concrete was poured for that. No grading work occurred this week.
Week of July 22
Grading work continued. Work began on pier stems.
Week of July 15
The steel piling placement has been completed for pier 1 and the new pier 0. The west abutment concrete has been placed, as well as the footings for piers 0 and 1. Only minor grading work was performed this week. Next week, work will begin on the pier stems.
Week of July 8
The concrete footings for the west abutment and pier 2 have been poured. The drilled piling for pier 1 has been completed. The installation of the driven piling for the new pier 0 has started.
Grading work for the drainage channel slopes has continued.
Week of July 1
Grading work continued east of the bridge. Slope shaping continued on the west-side channel. Pile drilling for pier 2 was completed. Crews drove the H-Piling for the west abutment. Bridge forming materials were delivered to the job site.
Week of June 24
Wet weather slowed progress on grading work again this week. Crews placed embankment material at the proposed east abutment location and graded the slopes along the drainage channel north of the bridge. Crews began installation of the 12-foot pipe-piling for Pier 2. Each rotary-drilled piling is approximately 40-feet-long and will be embedded 5-feet to 8-feet into ledge rock.
Week of June 17
Engineering staff determined that the soils beneath the surcharge were less stable than early analysis revealed. Rather than rely on only the surcharging process to strengthen the soil, an additional bridge pier and 95-foot-long span will be added, which will push the west bridge abutment into the area of the existing road core that was not disturbed during the washout, and the need for additional surcharge will be eliminated. This will also allow for the construction of flatter finished slopes, which will reduce the weight of the embankment on the underlying unstable soils.
The cost of project will increase due to this plan revision. The additional cost is still being determined. The number of trucks hauling material into the project is not expected to increase as a result of this plan change. The project is still scheduled to be completed this year.
Rock drilling for two of the center piers will begin next week. Folks living close to the site may hear noise generated by this work.
Week of June 10
Work continued on the placement of surcharge* for the west abutment. Clearing work continued on the east-side of the proposed bridge. A temporary access-road for crane-access to piers 1 and 2 was completed. Temporary crane-pads were constructed near piers 1 and 2 to provide a stable base for the cranes to sit on during all phases of the bridge construction.
*In areas where poor-quality soils have been identified, engineers use surcharge to improve the density and quality of the soil. This is accomplished by piling loads of rock/gravel over the area of poor soil. This rock/gravel is called surcharge. The surcharge is left in place for varying amounts of time depending on the soil analysis of the poor soil beneath it. Over time, the weight of the surcharge compacts the poor soil and makes it more stable.
A public meeting held June 4 in Carlton drew a large group of citizens interested in learning more about the Hwy 210 new bridge project. MnDOT and Minnesota Power Company engineers were on-hand to hear attendees concerns and answer questions.
The concerns discussed included dust control, road maintenance, noise and speeding. MnDOT plans to address these issues on a regular basis.
Dust: Dust will be controlled with applications of calcium chloride and water.
Road maintenance during construction: Graders will be used to blade the roads being used by trucks hauling material to the construction site.
Noise: Both Minnesota Power and MnDOT are making efforts to control noise as much as possible. Minnesota Power has stipulated that its contractor can only install pilings during daylight hours. They are using a "sheet vibrating" process that is quieter than other processes. Construction of the new Hwy 210 bridge will require two-to-three weeks of pile driving.
Speeding: The posting speed in the construction area is 30 mph. This speed will be enforced.
Brian Larson, MnDOT D1 resident engineer, listens and takes notes as a citizen comments about the project.
