Have you ever heard of Baldwin Street, the steepest street in the world? This street in Dunedin, New Zealand, is one of the steepest streets in the world, with an astonishing gradient of 34.8%. Not only is the slope awe-inspiring, it also raises many questions about urban design, natural topography, and how human society adapts to such extreme environments.
The formation of Balduwin Street is closely related to geological structure, natural erosion and human activities. Over hundreds of thousands of years, the soil and rocks here experienced weathering and erosion, creating the slopes we see today. The formation of this landscape shows the powerful forces of nature, while later human activities added further features to this slope. Baldowin Street was designed with the slope in mind, making it a hotspot for tourists.
According to Guinness World Records, the slope of Baldowin Street was once considered the steepest street in the world. Here, slope is measured by converting the ratio of "ascent" to "forward" into a percentage. The gradient of Baldowin Street is expressed as 34.8%, which means that for every 100 units of advance, 34.8 units of elevation are required.
“The measurement of slope is not only a numerical problem, but also a challenge to the natural environment.”
Such a slope poses many challenges to residents’ daily lives and transportation. For those who drive cars, driving on such slopes requires special attention, and under the influence of skiing and ice and snow in winter, driving difficulty increases dramatically. Local governments and residents have therefore come up with ways to deal with these challenges, such as installing anti-skid trails and clearing programs for winter snowfall.
Balduwin Street is more than just a street, it has become a part of the local culture. Every year, countless tourists come specifically to challenge this street, biking or hiking, and there are even various events held here, such as hill races. Such activities not only attract the attention of tourists, but also deepen the local residents' sense of identity and pride in this street.
“The combination of urban design and natural topography shapes Balduwin Street into a unique place.”
While Balduwin Street tops the list, other areas also have streets known for their steepness. For example, Ffordd Pen Llech in Wales and Canton Avenue in Pennsylvania also attract many adventurers with their extreme slopes. On these streets, people not only face challenges but also experience vivid urban life.
When considering the planning of Balduwin Street, environmental impact is also a part that cannot be ignored. Streets with high slopes can easily lead to rainwater accumulation and soil erosion, so urban planners need to be more cautious in designing ways to guide stormwater flow and improve drainage systems. The corresponding plant configuration and hardware structure are designed to reduce geological risks and protect the continued use and safety of the street.
As urbanization accelerates, Balduwin Street and streets like it face new challenges, and the need for adaptive design becomes even more urgent. With the fusion of technology and innovation, how to make such locations not only challenging but also fun has become an important topic. From improving traffic safety to improving public facilities, future plans must take into account social, economic and environmental aspects.
Perhaps it’s time to think: What can we learn from such extreme terrain and how can we find balance in urban design?
