Columbus市中心I-71南向高架匝道第二车道开通 2.8亿美元市中心匝道工程预计今秋完工
位于俄亥俄州富兰克林县的Columbus市，据《Columbus电讯报》10月14日报道，俄亥俄州交通厅当天开通市中心71号州际公路南向高架匝道的第二条车道。今后从70号州际公路西向或芒德街驶上匝道的车辆无需再并入单车道通行。
该匝道自去年12月开通以来一直限单车道运行，施工人员同期完成第二车道及周边州际公路工程。交通厅第6区10月14日通过社交媒体视频宣布开通消息。
这条高架匝道属于交通厅「市中心匝道提升」项目第4R／6R阶段，工程造价2.8亿美元，2022年开工，预计今年秋季末完工。在此之前，驾驶人从已关闭的三街匝道驶入70号公路西向后，须在一英里内跨越三条车道才能留在71号公路南向车道。

Second Lane Opens on I-71 Southbound Flyover Ramp in Downtown Columbus; $280 Million Phase Due This Fall
Columbus is a city in Franklin County, Ohio. The Columbus Dispatch reported on October 14 that the Ohio Department of Transportation opened a second lane that day on the Interstate 71 southbound flyover ramp in downtown Columbus. Drivers entering the ramp from Interstate 70 westbound or Mound Street no longer have to merge into a single lane.
The ramp had been restricted to one lane since it opened in December while crews finished the second lane and nearby interstate work. ODOT's District 6 announced the opening in an October 14 social media video.
The flyover is part of Phase 4R/6R of ODOT's Downtown Ramp Up project, a $280 million phase started in 2022 and expected to finish by the end of fall. Before the ramp opened, drivers merging onto I-70 west from the now-closed Third Street ramp had to cross three lanes in less than a mile to stay on I-71 south.
