Richmond-San Rafael大桥西行今夜全封9小时，安装开放式道路收费龙门架
加州交通厅（Caltrans）第四区通告：Richmond-San Rafael大桥西行方向将于11月14日（周六）23时至15日（周日）8时全线封闭9小时，封闭段自Canal Street与Castro Street一带起，施工内容是为大桥安装新的高架收费龙门架系统，驾车人须提前改道。
这座大桥将成为湾区州属桥梁中第一座改用高架读取器的开放式道路收费（open road tolling）的桥梁：车辆无需在收费站减速停车，龙门架上的设备在车辆通过时自动读取车牌与 FasTrak 标签完成扣费。封闭期间，桥上的行人和自行车通道也同步关闭。
Caltrans给出的绕行路线是：西行车辆改走37号州道（SR-37）西行，再转101号国道（US-101）南行，前往Marin县一侧。由东湾前往Marin县、圣拉斐尔（San Rafael）方向的车程将明显增加，建议预留额外时间。
Richmond-San Rafael大桥横跨旧金山湾北部，连接Contra Costa县的Richmond与Marin县的San Rafael，是580号州际公路东湾段的关键通道，平日承担大量跨湾通勤车流，因此施工安排在周六深夜至周日清晨的车流低谷时段。

Richmond-San Rafael Bridge Westbound to Close for Nine Hours Tonight for Open-Road Tolling Gantry Installation
Caltrans District 4 has announced that the westbound direction of the Richmond-San Rafael Bridge will be fully closed for nine hours, from 11 p.m. on Saturday, November 14 to 8 a.m. on Sunday, November 15, beginning around Canal Street and Castro Street, so crews can install a new overhead toll gantry system; drivers should plan alternate routes.
The bridge will become the first state-owned bridge in the Bay Area to convert to open-road tolling with overhead readers: instead of slowing down at a toll plaza, drivers will be charged automatically as gantry-mounted equipment reads license plates and FasTrak tags at highway speed. The bridge's bicycle and pedestrian path will also be closed during the work.
The signed detour takes westbound drivers onto State Route 37 westbound and then south on U.S. Highway 101 toward the Marin County side. Trips from the East Bay toward Marin County and San Rafael will take considerably longer, and drivers are advised to allow extra time.
The Richmond-San Rafael Bridge carries Interstate 580 across the northern reach of San Francisco Bay between Richmond in Contra Costa County and San Rafael in Marin County, handling heavy cross-bay commute traffic on weekdays — which is why the closure is scheduled for the late-Saturday-night to early-Sunday window.
