About the project

View full-sized image

We will make improvements on Hwy 14 from east of Hwy 56 in Dodge Center to west of Co. Rd. 5 / 2nd Ave. in Byron. Construction will take place spring 2024 and end late summer 2024. The project includes the following improvements:

The team looked at the three other intersections between Kasson and Byron. This project will not make changes at those intersections. We will take another look with a future project.

Rd. 9 intersection, looking norths a high risk for severe crashes due to the multi-lane crossing and high traffic speeds. There have been 18 crashes in the past ten years. Three of these crashes involved injuries and one resulted in a fatality. The project team evaluated several options and collaborated with stakeholders and the community. The community also reviewed the options and provided feedback at several public meetings. The preferred option is to build a J-turn at the Hwy 14 and Co. Rd. 9 intersection.

  • Construction Staging

    Share Construction Staging on Facebook Share Construction Staging on Twitter Share Construction Staging on Linkedin Email Construction Staging link

    Construction Stage 1

    Construction will occur in two stages; inside lanes and outside lanes. The contractor will determine which stage will occur first. However, the bridge improvements at Hwy 57 will start with the inside lanes. Once construction begins, vehicles will not be able to cross or turn left onto Hwy 14 from Co. Rd. 9. One lane of traffic in each direction on Hwy 14 will be open throughout construction.

    Stage one construction will include:

    • Median U-turns and left turn lanes at Co. Rd. 9*
    • High-tension cable median barrier installation*
    • Bridge approach panels
    • Overlay

    *When these items are complete, stage 2 will begin, even if stage 1 bridge and overlay work is still being done. This will minimize the need for the Co. Rd. 9 detour.

    Crashes


    View full-sized image


    In the past ten years, there have been 18 crashes at Co. Rd. 9

    Among the 18 crashes:

    • Three were north of Hwy 14 at the railroad crossing
    • Three were run off the road, not specific to the intersection

    Crossing or turning left across oncoming traffic is the number one risk at intersections like Hwy 14 and Co. Rd. 9. This type of crossing has more conflict points, which leads to more frequent and severe crashes.

    J-turn Intersection

    What is a J-turn?

    A J-turn is an intersection type used to decrease risk of fatalities and injuries. With a J-turn, drivers from the side street only have to be concerned with one direction of traffic on the highway at a time. Drivers only need to wait for a gap in one direction at a time to cross.

    What are the benefits?

    Improved safety: Studies show an 86 percent reduction in fatalities and a 46 percent reduction in injury crashes where J-turns are used.

    Faster to build: J-turns can be designed and built in approximately one year. Interchanges typically take 3-5 years.

    Lower cost: J-turns are a fraction of the cost of building an overpass or interchange

    How are they used?

    Motorists approaching divided highways from a side street are not allowed to make left turns or cross traffic; instead, they will turn right onto the highway and then make a U-turn at a designated median opening. This reduces conflict points and increases safety.

    We are moving forward with the design of Alternative 1 for the Hwy 14 and Co. Rd. 9 intersection.

    Two J-turn designs were evaluated. Alternative 1 allows drivers to turn left from Hwy 14 directly onto Co. Rd. 9. Alternative 2 requires drivers turning left off of the highway to use the median U-turn. We found that a majority of community members preferred Alternative 1 over Alternative 2.

    With Alternative 1, drivers approaching Hwy 14 from Co. Rd. 9 will not be able to turn left at the intersection where they do today. Instead, drivers will turn right into a wide left turn lane and then make a U-turn at a designated median opening. This means that drivers from Co. Rd. 9 will only have to look in one direction of traffic on Hwy 14 at a time.

    The design also features a wider shoulder and U-turn space. This will help large vehicles and agricultural equipment maneuver through the J-turn. Drivers will benefit by reduced travel time for vehicles crossing the highway. Separate left turn lanes will keep Hwy 14 traffic separate from traffic entering from Co. Rd. 9.

    Hwy 14 and 260th Ave. intersection

    After initial community feedback, we decided to not close the median at the Hwy 14 and 260th Ave. Future plans for the intersection will be discussed in future projects.

    Future public meeting

    A third public meeting will be held in 2023. The goal will be to let people know what they can expect from construction in 2024. We will also have information on how to navigate a J-turn.

    Thank you for your input over the last year. We began reaching out to the community in May 2022. This included in-person and virtual public meetings, online and paper surveys, newspaper and social media advertisements, as well as letters, postcards and emails to stakeholders. The feedback that we received has been incredibly helpful in determining the next steps of the project.

    As part of our design process, we gather information to help us make a choice about what changes to make. They have looked at the condition of the road surface, crash data, and more.

    Crash statistics show there is a safety risk at Hwy 14 and Co. Rd. 9. The crash data has also helped our engineers understand why those crashes happened. However, some information does not get reported. Things like near misses, or how the intersection services agricultural needs are examples.

    Feedback from the community will help us:
    • Understand issues and needs at the intersection
    • Assess improvements or alternatives that meet the needs of all highway users

    We presented these materials at a public meeting on September 20, 2022. People were asked to review then and participate in a survey. The survey has since closed.

    Crashes

    In the past ten years, there have been 18 crashes at County Road 9

    Crash pie chart showing 42% or 5 angle crashes including 1 fatality and 2 injuries all involving southbound motorists, 25% or 3 rear-end crashes with 1 injury, 25% or 3 sideswipe crashes, and 1 left turn crash

    Among the 18 crashes:

    • Three were north of Highway 14 at the railroad crossing
    • Three were run off the road, not specific to the intersection

    Crossing or turning left across oncoming traffic is the number one risk at intersections like Highway 14 and County Road 9. This type of crossing has more conflict points, which leads to more frequent and severe crashes.

    Reduced conflict intersection

    What is an RCI?

    Reduced Conflict Intersections (RCIs) are intersections that decrease fatalities and injuries. With an RCI, drivers from the side street only have to be concerned with one direction of traffic on the highway at a time. You don't need to wait for a gap in both directions to cross a major road.

    What are the benefits?

    Improved safety: Studies show an 86 percent reduction in fatalities and a 46 percent reduction in injury crashes where RCIs are used.

    Faster to build: RCIs can be designed and built in approximately one year. Interchanges typically take 3-5 years.

    Lower cost: RCIs are often less expensive than constructing an intersection with a stop light and are a fraction of the cost of building an interchange.

    How are they used?

    Motorists approaching divided highways from a side street are not allowed to make left turns or cross; instead, they will turn right onto the highway and then make a U-turn at a designated median opening. This reduces potential conflict points and increases safety.

    Sight distance

    Both design alternatives 1 and 2 allow for more than the required sight distance.

    What is sight distance? Sight distance is the distance along the road a person can see an object that is a specified height above the road. As sight distance gets shorter, drivers become less certain that it is safe to pull out onto the road.

    How much sight distance is needed? The rule of thumb we use is the distance an oncoming vehicle travels in 10 seconds. For a 70 MPH design, that distance is 1,029’. The drawings here show the sight distance for a passenger car (where the driver’s eye is 3.5’ above the ground) and a semi-truck (the driver’s eye is 7.6’ above the ground) and they want to see the windshield of an approaching car (3.5’ above ground).
