密西西比河新桥提前数月通车：1.65亿美元连接威斯康星与爱荷华，旧黑鹰桥将拆除
威斯康星州州长托尼·埃弗斯（Tony Evers）11月6日与威斯康星州交通厅（WisDOT）、爱荷华州交通厅官员及地方社区领袖一道，在爱荷华州兰辛（Lansing）庆祝密西西比河上新建的 WIS 82／Iowa 9 大桥通车。这座桥连接爱荷华州兰辛与威斯康星州克劳福德县，比原定的2027年春季通车时间提前了数月。
埃弗斯说：「兰辛新桥通车是威斯康星州和爱荷华州伙伴的一大成就，显示出跨州合作能为两州居民、企业和访客的生活带来怎样的便利。」威斯康星州交通厅厅长克里斯蒂娜·博德曼（Kristina Boardman）说，提前通车是各方辛勤工作与合作的成果，从跨州施工协调到维持临时轮渡服务，团队一路合作让两岸社区保持相连。
这项耗资1.65亿美元的密西西比河大桥工程于2023年底开工，取代历史悠久的黑鹰桥（Black Hawk Bridge）。黑鹰桥在2025年多次临时关闭后，于2025年底永久关闭。2025年11月起，两州交通部门合作提供免费临时汽车轮渡，弥补大桥施工期间的过河需求；轮渡运行约一年，运送车辆超过16万辆。
新桥使用了约11,400立方码混凝土和6,600吨钢材，外观仿照旧桥设计——旧桥是兰辛社区的标志。新桥基础深达150英尺，接近原收费桥基础深度的三倍；新桥车道和路肩更宽，预计每天通行约2,500辆车。整个工程有60多家承包商、咨询机构与行业伙伴参与。州长办公室称，埃弗斯任内全州自2019年以来已改善11,685英里道路和2,772座桥梁。
新桥通车后仍有收尾工程，包括恢复汽车轮渡码头区域、拆除旧桥桥墩与基础。2027年春季，桥面后续施工将带来交通干扰，但预计不需要完全关闭大桥。整个兰辛大桥工程预计2027年春末完工。

New $165 Million Mississippi River Bridge Opens Months Ahead of Schedule, Reconnecting Wisconsin and Iowa
Wisconsin Governor Tony Evers on November 6 joined the Wisconsin Department of Transportation (WisDOT), officials from the Iowa Department of Transportation and local community leaders in Lansing, Iowa, to celebrate the opening of the new WIS 82 / Iowa 9 Mississippi River bridge connecting Lansing, Iowa, and Crawford County, Wisconsin. The bridge opened months ahead of its original spring 2027 schedule.
"The opening of the new Lansing Bridge is a major achievement for Wisconsin and our partners in Iowa, and it shows just what we can accomplish when we work across state lines to make life easier for our states' residents, businesses, and visitors," Gov. Evers said. WisDOT Secretary Kristina Boardman said opening ahead of schedule was a testament to the hard work and partnership behind the project, from coordinating construction across two states to maintaining a temporary ferry service that kept the communities connected.
The $165 million Mississippi River Bridge project began in late 2023. The new bridge replaces the historic Black Hawk Bridge, which was permanently closed in late 2025 after temporary closures earlier in 2025 and in 2024. In November 2025, WisDOT and Iowa DOT partnered to provide free temporary car ferry service during construction; over its year of service, the ferry carried more than 160,000 vehicles.
The new bridge was built with about 11,400 cubic yards of concrete and 6,600 tons of steel and was designed to resemble the former structure, an icon of the Lansing community. Its foundations are 150 feet deep, nearly three times deeper than the original bridge built by a private toll company. The new bridge has wider traffic lanes and shoulders and is expected to carry about 2,500 vehicles daily. More than 60 contractors, consultants and industry partners worked on the project. The governor's office said Wisconsin has improved 11,685 miles of roads and 2,772 bridges statewide since 2019 under Evers.
Additional work remains, including restoration of the car ferry landing areas and removal of the prior bridge's piers and foundations. In spring 2027, further work on the bridge deck will cause traffic disruptions but should not require full closures. The entire Lansing Bridge project is expected to be completed in late spring 2027.
