Have you ever driven through an intersection that feels like a rollercoaster ride? Well, that's the experience awaiting drivers at the intersection of 55th Street NW and West Circle Drive in Rochester, Minnesota. Let's dive into this unique road design and explore why it's causing quite a stir.
The Hilly Intersection
Dear readers, today we're tackling a curious question from 'Driving Diane,' who wonders why this particular intersection was designed with such an extreme elevation change. It's a valid concern, as the sudden incline and decline can be a jarring experience, especially for those with low-hanging vehicles.
Historical Context
The story behind this intersection's design is an interesting one. When West Circle Drive was constructed three decades ago, it was designed as a high-speed county road with a 55 mph limit. The focus was on facilitating smooth traffic flow, and the 'superelevation' or banking of the road was a feature to help vehicles navigate the curve safely. However, the intersection with Members Parkway was an afterthought, and the original pavement remained unchanged.
A Complex Roadway System
Here's where it gets intriguing. West Circle Drive is an Olmsted County road, while 55th Street NW and Members Parkway are city roads. This intersection, therefore, is a collaboration between the city and county, reflecting their respective roles in the roadway system. The addition of Members Parkway and the removal of the Retail Drive intersection led to the creation of this unique crossing.
The Challenge of Change
One thing that immediately stands out is the challenge of retrofitting an intersection onto an existing road. When West Circle Drive was built, the 'grade breaks' within the median weren't a concern as there was no east-west movement. However, with the addition of Members Parkway, drivers now cross the superelevation at a right angle, creating the noticeable change in grade.
Personal Perspective
Personally, I find this situation fascinating. It's a perfect example of how infrastructure can evolve and adapt over time, often leading to unexpected outcomes. In this case, the original design of West Circle Drive, while suitable for its initial purpose, didn't account for future developments and the changing needs of the community.
A Speed Bump Solution?
One interesting take on this situation is the idea that this intersection could be seen as a natural speed bump. After all, it forces drivers to slow down and navigate carefully. However, as the Answer Man points out, this solution isn't without its drawbacks, especially for those with low-hanging vehicles.
Looking Ahead
What many people don't realize is that road design is a complex art, and every decision has consequences. In this case, the historical conditions and the collaboration between the city and county have led to a unique and challenging intersection. While there are no immediate plans to add signage, it's an interesting case study in the evolution of our roadways.
Final Thoughts
This intersection serves as a reminder of the importance of forward-thinking in infrastructure design. While it may be a challenge for some drivers today, it also offers a fascinating glimpse into the complexities of urban planning and the ever-evolving nature of our cities.
