Bunker Lake Boulevard (CSAH 116) from Armstrong Blvd (CSAH 83) to Sunfish Lake Blvd (CSAH 57)

This project is currently under construction.   Please see the Construction Weekly (https://www.anokacounty.us/1578/Construction-Weekly) for regular updates on this and other current construction projects.

Project Background


Anoka County, in partnership with MnDOT and the City of Ramsey, is developing construction plans for Bunker Lake Boulevard (CSAH 116) from Armstrong Boulevard (CSAH 83) to Sunfish Lake Boulevard (CSAH 57).  Construction is anticipated to begin in late summer of 2021, with completion of the work in November of 2021.

This project proposes to construct additional designated turn lanes, increase the length of merge lanes, restrict left turn movements at designated locations and driveways onto Bunker Lake Boulevard, and install a traffic signal system at the Sunwood Avenue intersection, along with lane geometric modifications, and other improvements along the corridor.

This project was developed from a MnDOT Traffic Management Study, where the focus of the study is to review anticipated traffic volume increases on parallel routes during construction of the Anoka Solution and Rum River Bridge project in the City of Anoka. Bunker Lake Boulevard is the only parallel route adjacent to Trunk Highway 10 and is currently a 2-lane county highway.

Current traffic volumes along the corridor are in the range of 5,000 – 9,300 vehicles per day; MnDOT has estimated the traffic volumes on Bunker Lake Boulevard will double in volume during morning and afternoon peak travel times. The increased traffic will occur during the construction years of 2022 through 2023. Anoka County is committed to ensure Bunker Lake Boulevard continues to be a safe and efficient 2-lane roadway with these proposed traffic volume increases.

Project Goals

  • Safely accommodate all users, including motor vehicles, freight, pedestrians, and bicyclists
  • Reduce impacts and avoid the natural resources and wetlands adjacent to the highway corridor, where appropriate
  • Provide efficient mobility and access for all modes of travel
  • Improve emergency response times to serve the community
  • Develop a financially responsible design, minimizing impacts to right-of-way and environmental resources
