TH 10 Add-a-Lane from Hanson Blvd to Round Lake Blvd

Project Summary

Project Background / Description
Anoka County, in partnership with MnDOT, the City of Coon Rapids, TKDA and HDR, are developing a layout for the addition of travel lanes on TH 10 between CSAH 78 (Hanson Boulevard) and CSAH 9 (Round Lake Boulevard).   The expansion of this corridor of TH 10 to six lanes will provide additional capacity and reduce traffic on the local roadway network.   The project is currently in the final layout design phase; construction is anticipated to begin in the summer/fall of 2024.

Project Goals
Provided below are the project goals being considered during the design and construction phase of this project:

  • Safely accommodate all users, including motor vehicles and transit
  • Provide efficient mobility and access for all modes of travel
  • Develop a financially responsible design, which minimizes right-of-way and environmental resource impacts
  • Reduce right-of-way impacts for multiple stakeholders

Highway Traffic Noise
This project is a Federally funded, Type I project. Federally funded projects are obligated to investigate and, if necessary, mitigate for noise related issues created by the project. 

The Minnesota Department of Transportation (MnDOT), Anoka County, and City of Coon Rapids recently conducted a noise study along Highway 10 as part of the Lane Addition project. The study determined noise walls constructed along Highway 10 in Coon Rapids would reduce the traffic noise level at various properties, units, or businesses by at least 5 decibels.  We have determined that there are four locations along the corridor where noise walls are being considered for construction; see the map below for those four locations.

Property owners and residents who will experience a 5-decibel reduction in noise from of a noise wall are eligible to vote for or against their proposed wall along Highway 10 in Coon Rapids; the proposed noise walls will not be constructed unless affected property owners want them constructed.   We are currently in the process of collecting votes to determine whether those affected by the proposed noise walls indeed want them constructed; the affected residents and property owners have received ballots and supplementary information via USPS mail.   If you have been identified as one of the property owners who is eligible to vote, you are encouraged to participate in the voting process.

How voting works
A weighted voting system is used to ensure residents and property owners are given appropriate influence on the outcome of the noise wall. How much each individual influences the outcome of the noise wall is based on how much their property/unit is affected by the noise wall and whether or not they own the property/unit. Only units in apartments/multi-family residential buildings receiving a 5-decibel reduction of noise may vote. Businesses, churches, and schools receive a vote equal to that of a property owner.

If 50 percent or more of all possible voting points from eligible voters are received after the first request for votes, the majority of points (based upon the votes received) determine the outcome of the noise wall. If less than 50 percent of the possible voting points for a wall are received after the first request, a second ballot will be mailed to the eligible voters who did not respond.

The voting deadline is DECEMBER 14, 2023. Results and/or a status update will be posted on this website when results become available.

If you have any additional noise wall related questions, please contact , or join us in-person on Wednesday, November 1, 2023 from 4:00 PM - 6:00 PM for an open house to learn more. The open house will be held at the Coon Rapids Civic Center, 11155 Robinson Drive, Coon Rapids, MN  55433. 

Project Team
The team for this project is represented from multiple agencies, including MnDOT, Anoka County, the City of Coon Rapids, and consultants from TKDA and HDR.

Provided below is an overview of the project schedule identifying key milestones in the process: 

  • Final Layout Design – Spring 2023 to Fall 2023
  • Final Design – Fall 2023 to Summer 2024
  • Public Open House – Fall 2023 
  • Construction – Summer/Fall 2024 – Spring 2025 

Public Involvement Meetings
Various stakeholders, ranging from permitting agencies to residents or property owners living and/or working along or near the roadway, have an interest in the improvement of this roadway intersection. Anoka County recognizes that these interests vary in perspective, and will use information provided by the various stakeholders when making decisions on final improvements. There are several activities that will occur throughout the design process that will allow for input from the various stakeholders. Agency and public involvement activities will be scheduled through the project’s development, and will include: 

  • Agency Coordination Meetings - Throughout the project development process, various individual agencies may have concerns regarding resources that could be impacted due to the project. Project Team staff will meet with the individual agencies throughout the project’s development to gain an understanding of the concerns and work through possible mitigation strategies and any necessary design improvements.

  • Presentations at Council Meetings – staff from TKDA, Anoka County and/or the City of Coon Rapids will present project information at City Council meetings and/or workshops, in order to educate and solicit input from elected officials about the benefits of the proposed project.

  • Public Information Meetings – staff from the Project Team will provide informational materials and maps at the open house(s) to be held beginning in the Fall, 2023.  Meeting notices will be mailed to surrounding property owners and residents along the corridor. Meeting notices will also be posted on this webpage. Meetings will be an open house style format and/or online, where County and City staff provide additional information and answer any questions that arise as meeting attendees look at various boards and maps of the proposed project. Comment cards for concerns, comments or questions will be provided at the meetings; the cards can be completed and left at the meetings, or be completed and mailed or dropped off at the Anoka County Highway Department offices, located in Andover. All verbal and written comments gathered during or after the meetings will be reviewed by staff.
