Officials in Kentucky and Ohio have selected a joint venture of Walsh Group and Kokosing Construction Co. for their Brent Spence Bridge Corridor Project, they announced July 27. The contract covers work estimated to cost $3.1 billion.肯塔基州和俄亥俄州的官员于 7 月 27 日宣布,已选择 Walsh Group 和 Kokosing Construction Co. 成立一家合资企业来开展布伦特·斯宾塞大桥走廊项目。该合同涵盖的工程预计耗资 31 亿美元。The plan calls for construction of a new bridge carrying Interstates 71 and 75 over the Ohio River between Cincinnati and Covington, Ky., plus improvements on 5 miles of I-71/75 in Kentucky and 1 mile of I-75 in Ohio. Officials have so far considered cable-stayed and arch bridge design options. The states opted for a progressive design-build contract with the joint venture, named Walsh Kokosing Design-Build Team, which officials say will help control material costs and allow for design revisions if necessary.该计划要求在辛辛那提和肯塔基州卡温顿之间修建一座横跨俄亥俄河、连接 71 号和 75 号州际公路的新桥梁,并对肯塔基州 5 英里的 I-71/75 公路和俄亥俄州 1 英里的 I-75 公路进行改进。 到目前为止,官员们已经考虑了斜拉桥和拱桥的设计方案。 各州选择与名为 Walsh Kokosing Design-Build Team 的合资企业签订渐进式设计建造合同,官员们表示,该合同将有助于控制材料成本,并在必要时允许进行设计修改。“This is one of the largest highway construction projects ever undertaken in the U.S.,” said Jim Gray, secretary of the Kentucky Transportation Cabinet, in a statement. “We are confident that Walsh Kokosing’s experienced team, with their solid track record of completing projects approaching this size, possesses the talent, skills and know-how to deliver this complex bridge and highway system.”肯塔基州交通内阁秘书吉姆·格雷在一份声明中表示:“这是美国有史以来最大的高速公路建设项目之一。” “我们相信 Walsh Kokosing 经验丰富的团队拥有完成如此规模项目的良好记录,拥有交付这一复杂桥梁和公路系统的人才、技能和专业知识。”Officials also plan improvements on a 2-mile stretch of I-75 in Ohio at an estimated cost of $500 million, which would be done under a separate contract. That would also include construction of a new interchange at Cincinnati’s Western Hills Viaduct.官员们还计划对俄亥俄州 2 英里长的 I-75 公路进行改进,预计成本为 5 亿美元,这将根据单独的合同完成。 这还包括在辛辛那提西山高架桥建设一个新的立交桥。The project team also includes design and engineering firms AECOM, Parsons and Jacobs, plus diversity, inclusion and outreach consultant WEB Ventures, according to the joint announcement from Kentucky Gov. Andy Beshear (D) and Ohio Gov. Mike DeWine (R). The states also enlisted a consulting team led by HNTB with HMB Professional Engineers Inc., American Structurepoint Inc. and Rasor.根据肯塔基州州长 Andy Beshear(民主党)和俄亥俄州州长 Mike DeWine(共和党)的联合声明,该项目团队还包括设计和工程公司 AECOM、Parsons 和 Jacobs,以及多元化、包容性和外展顾问 WEB Ventures。 各州还招募了一支由 HNTB 领导、HMB Professional Engineers Inc.、American Structurepoint Inc. 和 Rasor 组成的咨询团队。The project is aimed at improving traffic flow and safety. It would include improvements to the existing cantilevered steel-truss Brent Spence Bridge, which currently carries the highways and sees average daily traffic of more than 163,000 crossings, far more than what it was designed to handle. The existing bridge has four lanes in each direction but no emergency lanes. The new two-level bridge would have five lanes in each direction plus emergency lanes, though its design has not yet been finalized. Following construction of the new bridge, the existing bridge would be reconfigured to carry local traffic.该项目旨在改善交通流量和安全。 其中包括对现有悬臂式钢桁架布伦特斯宾塞大桥进行改进,该大桥目前承载着高速公路,日均交通量超过 163,000 人次,远远超过其设计容量。 现有桥梁每个方向有四车道,但没有应急车道。 这座新的两层桥将在每个方向有五个车道以及紧急车道,但其设计尚未最终确定。 新桥建成后,现有桥梁将被重新配置以承载当地交通。John Householder, president of Kokosing Construction, emphasized in a statement the importance of the bridge corridor for freight transportation and called the project “a once-in-a-lifetime opportunity to transform this vital connector.”Kokosing Construction 总裁 John Householder 在一份声明中强调了桥梁走廊对货运的重要性,并称该项目是“改造这一重要连接器的千载难逢的机会”。“The Brent Spence Bridge Corridor plays a key role in the Greater Cincinnati region and throughout Ohio and Kentucky, while also connecting Michigan to Florida and New York to Los Angeles,” Householder said.豪斯霍尔德说:“布伦特斯彭斯大桥走廊在大辛辛那提地区以及整个俄亥俄州和肯塔基州发挥着关键作用,同时也连接密歇根州和佛罗里达州以及纽约州和洛杉矶。”Kokosing was also previously the general contractor for an emergency rehabilitation project on the bridge after it was damaged in 2020 by a truck fire.Kokosing 此前也是该桥紧急修复项目的总承包商,该项目在 2020 年因卡车火灾而受损。As ENR previously reported, the U.S. Dept. of Transportation’s Federal Highway Administration announced in January that it would provide a $1.385-billion grant for the project through the Infrastructure Investment and Jobs Act-funded Bridge Investment Program. FHWA officials also said the project was set to receive $642 million in other federal funding.据 ENR 此前报道,美国交通部联邦公路管理局今年 1 月宣布,将通过基础设施投资和就业法案资助的桥梁投资计划为该项目提供 13.85 亿美元的赠款。 FHWA 官员还表示,该项目将获得 6.42 亿美元的其他联邦资金。The project has been through years of planning, but languished without funding. Ohio Dept. of Transportation and KYTC officials say more than 300 firms participated in an industry forum last year. They issued a request for proposals for design-build services in February.该项目已经筹划多年,但由于缺乏资金而陷入停滞。 俄亥俄州交通部和 KYTC 官员表示,去年有 300 多家公司参加了行业论坛。 他们在二月份发布了设计建造服务提案征求书。Work is expected to start late this year and officials anticipate completion in 2030.预计工程将于今年年底开始,官员预计将于 2030 年完工。
