The Third Avenue Bridge crosses the Harlem River between Manhattan at 129th Street and the South Bronx at 132nd Street. The NYC Live Command Center carries the NYCDOT camera feed for this crossing, giving a real-time view of one of the Harlem River's smaller but consistently active moveable bridges.

The Third Avenue Bridge is a swing bridge — a moveable structure that rotates horizontally to allow river traffic to pass. Completed in 1898 and rebuilt in 1898-1899, the current bridge dates from the early 20th century and is operated by the City of New York. It's one of several moveable bridges crossing the Harlem River between upper Manhattan and the Bronx.
عندما يفتح الجسر أمام حركة المرور النهرية، يتم حظر حركة مرور المركبات حتى يتم إغلاقه مرة أخرى. يلتقط موجز الكاميرا هذه اللحظات، التي تحدث عندما تحتاج القاطرات أو المراكب أو السفن الترفيهية إلى المرور. تستغرق عمليات فتح الجسر حوالي 10 إلى 15 دقيقة وتتطلب إشعارًا مسبقًا لمشغل الجسر.
The Bridge's Location and Traffic Role
يحمل جسر الجادة الثالثة حركة المرور في الجادة الثالثة بين Manhattan وBronx، ويربط الممر التجاري في الجادة الثالثة في شرق هارلم مع الجادة الثالثة في جنوب Bronx. يمتد الجادة الثالثة في هذا القسم من Bronx شمالًا عبر Mott Haven ويستمر كشارع تجاري مهم في جنوب Bronx.
For vehicle traffic, the Third Avenue Bridge is one of the lower-traffic-volume Harlem River crossings because it doesn't serve a major highway connection and it's a moveable bridge (which means it can be delayed by river traffic). Higher-volume crossings nearby include the Triboro Bridge to the east and the Madison Avenue Bridge and Third Avenue Bridge cluster further west.
معابر نهر هارلم كنظام
هناك ما يقرب من عشرة معابر لنهر هارلم بين Manhattan العلوي وBronx، بدءًا من جسر تريبورو (الأكبر) إلى العديد من الجسور المتحركة مثل جسر الجادة الثالثة. يحمل جهاز NYC Live Command Center لقطات الكاميرا للعديد من هذه المعابر، ومشاهدتها معًا تعطي فكرة عن كيفية توزيع حركة المرور عبر نهر هارلم.
On days when a major crossing is constrained , the Triboro has a traffic incident, or the Major Deegan upstream is backed up , the smaller bridges like Third Avenue absorb some overflow traffic. The camera at Third Avenue Bridge shows this overflow effect when it happens: a noticeable increase in vehicle volume on a structure that normally operates well under capacity.
جنوب Bronx في الجادة الثالثة
حي South Bronx الذي يمكن رؤيته من كاميرا Third Avenue Bridge هو منطقة Mott Haven وHunts Point. لقد شهد هذا القسم من Bronx تغييرًا كبيرًا منذ أدنى مستوياته في السبعينيات، مع الاستثمار السكني والتجاري المستدام خاصة في العقد الماضي.
The camera shows the transition between the bridge structure and the South Bronx street grid: Third Avenue in this area has a lower building scale than the Manhattan side, more surface parking, and a commercial strip that reflects the neighborhood's working-class character rather than the tourist or office-district character of the neighborhoods across the river.
مشاهدة جسر مفتوح
One of the more unusual things visible on the كاميرا جسر الجادة الثالثة , less common on the large fixed bridges , is the bridge opening cycle. When a vessel needs to pass through the Harlem River at this point, the bridge operator receives a request, barriers drop on the vehicle roadway, and the bridge span swings open on its central pivot. Waiting vehicles at both the Manhattan and Bronx ends stop, the vessel passes, and the bridge swings back to its closed position before vehicle traffic resumes.
This takes place a handful of times per day depending on river traffic, and the camera captures it in full. Watching a moveable bridge in operation is a piece of New York infrastructure that most residents who don't cross at this specific point have never seen.
