91号州道东向连续两个周末55小时收缩车道：Corona涵洞更换施工
加州交通局（Caltrans）提醒，位于加州河滨县Corona市的91号州道东向路段，将连续两个周末实施55小时车道封闭：第一轮为11月6日（周五）晚10时至11月9日（周一）清晨5时，第二轮为11月13日晚10时至11月16日清晨5时，封闭区间在241号州道与Green River Road之间，施工点位于Green River Road以西。
封闭期间东向仍保留三条车道通行，但北向241号州道通往东向91号州道的连接道、东向Gypsum Canyon Road入口匝道与东向Green River Road出口匝道将全线关闭。交通局呼吁驾驶人绕行避堵、按绕行指示行驶，并在施工区附近减速，注意运送物料进出工区的车辆与设备。
这项施工属于总投资600万美元的涵洞更换工程：拆除并更换现有82英尺长的涵洞段，同时改善野生动物穿越通道的衔接。工程2025年秋季开工，预计2027年秋季完工；封闭安排视天气与物料情况可能变更或取消。（来源：加州交通局）
Eastbound SR-91 Faces Two Straight 55-Hour Lane Closures: Culvert Replacement in Corona
Caltrans advises that eastbound State Route 91 in the City of Corona, Riverside County, California, will see two consecutive 55-hour lane closures between State Route 241 and Green River Road: the first from 10 p.m. on Friday, November 6, to 5 a.m. on Monday, November 9, and the second from 10 p.m. on Friday, November 13, to 5 a.m. on Monday, November 16. The work takes place just west of Green River Road.
Three lanes will remain open to eastbound traffic during the closures, but the northbound SR-241 to eastbound SR-91 connector, the eastbound Gypsum Canyon Road on-ramps and the eastbound Green River Road off-ramp will be fully closed. Caltrans asks drivers to seek alternate routes, follow detour signage and slow down near the work zone, where equipment and vehicles will be moving material in and out.
The closures support a $6 million project to demolish, excavate and replace 82-foot-long segments of the existing culvert while improving wildlife crossing linkage. Work began in fall 2025 and is expected to be completed by fall 2027; the closures are weather and material dependent and may be changed or canceled. (Source: Caltrans)
