I-90 South Dakota Ramp Closure

Navigating teh Interstate 90 Brandon Interchange Project: What Drivers Need to Know

The ongoing Diverging Diamond Interchange (DDI) construction project on Interstate 90 (I-90) near brandon, South Dakota, is entering a new phase that will affect eastbound traffic. Understanding these changes is crucial for commuters and travelers alike to minimize disruptions and ensure safe travels. Motorists need to stay informed to navigate detours and understand the long-term benefits of this infrastructure upgrade.

Eastbound On-Ramp Closure at Exit 406: What’s Changing?

Beginning may 12, the eastbound on-ramp to I-90 at Brandon (Exit 406) will be closed.This closure is a necessary step in the construction of the Diverging Diamond Interchange,a design aimed at improving traffic flow and reducing accidents. This closure can cause additional delays for motorists if they aren’t prepared.

Detailed Detour Information: Avoiding the Closure

If you’re planning to travel eastbound on I-90, you’ll need to use Exit 410. Follow the signed detour route, which utilizes S.D. Highway 11, County Road 138 (Aspen Boulevard), and County Road 105.Plan your route in advance to avoid unexpected delays.

Pro Tip: Download a real-time traffic app like Google Maps or Waze to get up-to-the-minute traffic updates and detour suggestions. These apps can help you avoid congestion and find the fastest route around the closure.

Closure Timeline: How Long Will the Detour Be in Place?

According to the South Dakota Department of Transportation (SDDOT), the closure and detour will be in place until mid-July 2025. This extended timeline is due to the complete reconstruction of the eastbound on-ramp at Exit 406. Patience and planning are key during this period.

Project Scope: What Does the Reconstruction Involve?

The second phase of this DDI project is complete. It includes:

• Completing the remaining on- and off-ramps
• Reconstructing the eastbound lanes of I-90
• Rebuilding the Exit Bridge
• Replacing the eastbound I-90 bridge over the BNSF railroad

This phase of construction will continue until November. The entire $41.3 million project is slated for completion in June 2026. Once completed, the DDI is expected to substantially improve traffic flow and safety in the area.

Did You Know? Diverging Diamond Interchanges have been shown to reduce traffic accidents by as much as 50% compared to conventional intersections. The design minimizes conflict points and allows for smoother turns.

Benefits of a Diverging Diamond Interchange: Why the Change?

Diverging Diamond Interchanges (DDIs) offer several advantages over traditional interchanges:

• Reduced Congestion: DDIs allow for more efficient traffic flow, especially during peak hours.
• Enhanced Safety: Fewer conflict points reduce the likelihood of accidents.
• Improved Pedestrian Access: DDIs frequently enough include dedicated pedestrian crossings, enhancing safety for those on foot.
• Cost-Effective: DDIs can often be built within the existing right-of-way, reducing the need for extensive land acquisition.

Across the United States, states like Missouri and Utah have successfully implemented DDIs, resulting in significant improvements in traffic management.

Construction Timeline: Major Milestones

Milestone	Anticipated Completion
Eastbound on-Ramp Closure at Exit 406	May 12
Eastbound On-Ramp Reconstruction Completion	Mid-July 2025
Phase Two Construction Completion	November
Overall Project Completion	June 2026

Future Trends in Interchange Design: Beyond the DDI

While Diverging Diamond Interchanges represent a significant advancement in traffic management,transportation engineers are continually exploring new designs and technologies. Some emerging trends include:

• Roundabouts: Increasingly used in urban and suburban areas to improve traffic flow and reduce accidents.
• Smart Intersections: Employing sensors and algorithms to optimize traffic signal timing in real-time.
• connected Vehicle Technology: Allowing vehicles to communicate with each other and with infrastructure to improve safety and efficiency.

These innovations promise to make our roadways safer and more efficient in the years to come.

FAQ: Your Questions Answered About The I-90 Brandon project

Why is the eastbound on-ramp at Exit 406 closed?

The on-ramp is closed for reconstruction as part of the Diverging Diamond Interchange (DDI) project, aimed at improving traffic flow and safety.

How long will the detour be in place?

The detour will be in place until mid-July 2025, as the eastbound on-ramp is fully reconstructed.

What is a Diverging Diamond Interchange (DDI)?

A DDI is a type of interchange where traffic temporarily switches to the opposite side of the road, allowing for easier and safer left turns onto and off the highway.

Where can I find updates on the project?

Check the South Dakota Department of Transportation (SDDOT) website,local news outlets,and SDDOT’s social media channels for the latest updates.

Q: Considering the potential impact on local businesses during this I-90 Brandon Interchange project, what specific strategies could be implemented to mitigate any negative effects on their revenue?

navigating the I-90 Brandon Interchange Project: An Interview with Transportation Engineer Amelia Hayes

Welcome to Archyde News. Today, we have Amelia Hayes, a leading Transportation Engineer, to discuss the ongoing I-90 Brandon Interchange project. Amelia,thanks for joining us.

An Overview of the Project

Archyde News: Amelia, can you give us a general overview of the Interstate 90 Brandon Interchange project and what it entails?

Amelia Hayes: Certainly. The project involves constructing a Diverging Diamond Interchange (DDI) at the Brandon interchange. This is a significant upgrade designed to improve traffic flow, reduce accidents, and ultimately, enhance the commuter experience in Brandon and the surrounding areas.
