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.

ライブカメラを見る三番街橋とは
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.
川の通行のために橋が開くと、再び閉じるまで車両の通行が遮断されます。カメラフィードは、タグボート、はしけ、またはレクリエーション船が通過する必要があるときに発生するこれらの瞬間を捉えます。橋の開通には約 10 ～ 15 分かかりますが、橋の管理者への事前通知が必要です。
The Bridge's Location and Traffic Role
三番街橋は、Manhattan と Bronx の間の三番街の交通を運び、イーストハーレムの三番街の商業回廊と南 Bronx の三番街を接続します。 Bronx のこのセクションの 3 番街は、モット ヘブンを通って北に伸び、Bronx 南部の重要な商業通りとして続いています。
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.
システムとしてのハーレム川渡河
Manhattan 上流と Bronx の間には、トライボロ橋 (最大) からサード アベニュー橋などのいくつかの可動橋まで、ハーレム川を渡る橋が約 12 か所あります。 NYC Live Command Center は、これらの交差点のいくつかのカメラ フィードを伝送しており、それらを一緒に見ることで、ハーレム川の交通がどのように分散しているかを把握できます。
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.
三番街の南Bronx
サード アベニュー ブリッジのカメラから見える南 Bronx 地区は、モット ヘブンとハンツ ポイント エリアです。 Bronx のこのセクションは、1970 年代の最低点以来、特に過去 10 年間の継続的な住宅および商業投資により、大きな変化を遂げてきました。
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.
橋が開くのを眺める
One of the more unusual things visible on the 三番街橋のカメラ , 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.
