【欢迎来到卡努萨街 Canusa Street：一条横穿美国/加拿大的街】
想象一下，你向街对面的邻居挥手，但他们身处完全不同的国家，受不同的联邦法律管辖，如果你不先通过海关就穿过人行道打招呼，你会被罚款。

欢迎来到卡努萨街，这是北美最迷人的地理和法律异常现象之一。

加努萨街有何独特之处？

加努萨街位于魁北克斯坦斯特德和佛蒙特州毕比平原之间，直接沿着北纬 45 度线延伸。加拿大和美国之间的国际边界沿着道路中间的黄线延伸：

南侧：美国佛蒙特州毕比平原

北侧：加拿大魁北克省斯坦斯特德

相传在 1800 年代，测量员醉酒或粗心时，不小心将边界线划到了定居点的中间。当地人没有搬迁道路或房屋，而是简单地进行了适应。该名称本身是一个合成词：CAN + USA = Canusa。

基础设施和边境治理的主要经验教训

1. 双重法律框架
一条双车道街道在两种不同的法律体系下运作。

留在自己车道上的司机在各自国家内行驶，但越过中心线——无论是驶入邻居的车道还是去街对面的商店——都构成国际过境，须遵守报告法。

2.不断变化的地缘政治的影响

几十年来，该社区作为一个具有共享基础设施、相互联系的单一城镇运作。从历史上看，当地邮局甚至设有一名邮政局长和两个柜台，为客户提供两种货币的服务。

然而，9/11 事件后的安全转变改变了街道的日常运作。严格禁止街对面的非官方步行交通，用持续的边境监控、摄像头和执法监督取代了非正式的社区联系。

3、共享市政维护

沿街的维护需要非同寻常的协调：

公共服务：除雪、道路重铺和公用设施管理需要严格的协议，以便市政团队在其适当的领土范围内运作。

紧急情况：紧急服务在边境线附近响应时必须遵守严格的管辖协议。

当当地社区生活和国家边界重叠时，灵活性和明确的跨境框架对于保持社会运转至关重要。

Imagine waving to your neighbor across the street—except they are in a completely different country, governed by different federal laws, and you’ll get fined if you walk across the pavement to say hello without passing through customs first.

Welcome to Canusa Street (or rue Canusa), one of the most fascinating geographic and legal anomalies in North America.

What Makes Canusa Street Unique?

Located between Stanstead, Quebec and Beebe Plain, Vermont, Canusa Street runs directly along the 45th parallel. The international border between Canada and the United States runs right down the middle yellow line of the road:
South Side: Beebe Plain, Vermont, USA

North Side: Stanstead, Quebec, Canada

Legend has it that in the 1800s, drunk or careless surveyors accidentally drew the boundary line right through the middle of the settlement. Rather than moving the road or houses, locals simply adapted. The name itself is a portmanteau: CAN + USA = Canusa.

Key Lessons in Infrastructure & Border Governance

1. Dual Legal Frameworks

A single two-lane street operates under two separate legal systems.

Drivers staying in their lane travel within their respective nation, but crossing the centerline—whether to pull into a neighbor's driveway or visit a shop across the street—constitutes an international border crossing subject to reporting laws.

2. The Impact of Evolving Geopolitics

For decades, the community operated as a single interconnected town with shared infrastructure. Historically, the local post office even featured one postmaster with two counters serving customers in both currencies.

However, post-9/11 security shifts transformed the street's daily operations. Unofficial foot traffic across the street was strictly prohibited, replacing informal community ties with continuous border monitoring, cameras, and law enforcement oversight.

3. Shared Municipal Logistics

Maintenance along the street requires unusual coordination:

Public Services: Snowplowing, road repaving, and utility management require strict protocol so municipal teams operate within their proper territorial boundaries.

Emergencies: Emergency services must navigate strict jurisdictional protocols when responding near the border line.

When local community life and national boundaries overlap, flexibility and clear cross-border frameworks become essential to keeping society moving. http://t.cn/AXlliXwZ
