74号州道Ortega公路拓宽安全工程进入收尾阶段：9,610万美元改造埃尔西诺湖段
加利福尼亚州交通厅（Caltrans）74号州道（Ortega Highway）车道拓宽与安全工程正在河滨县埃尔西诺湖市（Lake Elsinore）附近推进。据交通厅项目页，该工程总投资9,610万美元，施工范围为 Monte Vista Street 以西至 Grand Avenue 一段，内容包括拓宽车道与路肩并增设多项安全设施。
施工期间，Monte Vista Street（El Cariso Campground Road 以西）至 Grand Avenue 之间路段在工作日夜间晚8时至10时实行旗手交替放行；因该公路为狭窄的双车道山路、路肩有限，夜间全封闭将视需要实施，驾驶人应预留延误时间。
承包商 Granite Construction 表示，其承担的合同额约8,800万美元，工程内容包括拓宽路肩与路面、安装中央与边缘隆声带、重新铺设路面等，资金来自州与联邦渠道。工程自2025年4月开工，预计2026年11月完工。
Ortega 公路是连接橙县与河滨县的重要山区通道，穿越圣安娜山脉。加州交通厅提醒驾驶人行经施工区减速慢行，并通过项目页登记接收工程进度通知。

SR-74 Ortega Highway Safety Project Nears Completion: $96.1 Million Upgrade on the Lake Elsinore Stretch
The California Department of Transportation (Caltrans) State Route 74 (Ortega Highway) lane widening and safety project is advancing near the City of Lake Elsinore in Riverside County, California. According to the Caltrans project page, the $96.1 million project runs from just west of Monte Vista Street to Grand Avenue and will widen lanes and shoulders and add safety features along the mountain corridor.
During construction, weeknight flagging operations run from 8 p.m. to 10 p.m. between Monte Vista Street, west of El Cariso Campground Road, and Grand Avenue. Because Ortega Highway is a narrow two-lane road with limited shoulders, nightly full closures will occur as needed, and drivers should expect delays.
Contractor Granite Construction said its approximately $88 million contract covers widening the shoulders and roadway, installing centerline and edge line rumble strips and resurfacing, funded by state and federal sources. Construction began in April 2025 and is expected to be completed in November 2026.
Ortega Highway is a key mountain link between Orange and Riverside counties through the Santa Ana Mountains. Caltrans reminds drivers to slow down in the work zone and to sign up on the project page for construction updates.
