Project Overview
Highway 65 Corridor Study
The Minnesota Department of Transportation in partnership with Anoka County and the cities of Blaine, Ham Lake and Spring Lake Park are studying the Highway 65 (TH 65) corridor between Bunker Lake Boulevard and County Road 10/Mounds View Boulevard to identify cost-effective solutions to address the following issues:
Congestion |
| Access |
| Safety |
The study team collected and reviewed extensive data along the highway between 2013 and today. The team researched and modeled traffic conditions, studied crash data, and reviewed sidewalks and trails, wetlands, foodplains and land-use. The information that was collected helped to develop better understanding of key issues and problems for the study.

Problems and Considerations
Community Input and Corridor Insights
The first step in the study was to identify the key problems along this stretch of Highway 65. We do this by developing a “Purpose and Need statement”.
Project Need
The need is the problem to be solved.
Project Purpose
The purpose is what the project intends to do about the problem.
Next, we combined what we heard from the community with our own research and data to identify primary, secondary, and additional transportation problems and considerations for this corridor.
The primary transportation problems are:
The secondary transportation problem is:
Some additional transportation considerations are:
Identify Existing Solutions
Evaluate Effectiveness
The next step in the process is to look at several solutions to address these corridor issues. This is where we are now! We use the Purpose and Need discussed in the last slide to help determine if each proposed solution solves the transportation problems.
Our potential solutions must address the following questions in order to be considered:

If the solution proposed does answer these questions, then we look at other considerations such as:
Practicality
- Would the solution cause other traffic problems outside the corridor?
Natural and Built Environment
- Does the solution require additional right-of-way?
- What impacts to the environment does the solution have?
- Does the solution remove direct access to/from Highway 65 at certain locations or change how drivers currently travel through the area?
Implementation
- How much does it cost compared to the solution?
- What construction-related impacts does the solution have?
Explore New Solutions
Creative Ideas for Corridor Improvement
Traditional solutions, like major bridges and converting Highway 65 to a freeway, may not be feasible, so we’re exploring new tools, like innovative intersection designs, to make corridor improvements.
Innovative Intersection Benefits

Newer innovative intersections can improve safety and help move traffic better by reducing the number of different traffic movement such as right turns, left turns, through traffic and cross traffic.
We’re not sure what the solutions for the corridor will be yet, but the project team is evaluating what designs will work well and where, and gathering input from the public to understand their reactions to the new intersection designs.
