8.06 亿美元 I-270 走廊改造开工：1965 年通车的州际公路迎来首次升级
科罗拉多州州长 Jared Polis、科罗拉多州交通厅（CDOT）、联邦公路管理局（FHWA）、地方官员及承建商 Kiewit 公司 10 月 19 日为 I-270 走廊改造项目举行开工仪式，项目总投资 8.06 亿美元。这条州际公路东西贯穿 Adams 县与 Denver 北部，建成于 1965 年，是科罗拉多州唯一一条从未进行过升级改造的州际公路，目前每日车流量超过 10 万辆，远超设计承载能力。
改造完成后，I-270 每个方向将设两条普通车道和一条新增收费快速车道，公交车、摩托车及三人以上拼车可免费使用快速车道；项目还将更换 12 座建于 1960 年代的老化桥梁，重建 Vasquez Boulevard 立交，改善 I-76、York Street 和 Quebec Street 的匝道，并新增一座行人与自行车天桥。施工分三个阶段进行：今秋先启动土方工程，2027 年春季进入桥梁主体施工，第一阶段预计 2030 年初完工，全部工程预计 2033 年结束。
Polis 在开工仪式上说：「科罗拉多人每天靠 I-270 上班、回家、运送货物。这些改造将让 I-270 更安全、更可靠、更快捷，也将创造高薪岗位。」（GSM 据科罗拉多州交通厅新闻稿报道）
$806 Million I-270 Corridor Rebuild Breaks Ground: First Upgrade for Interstate Built in 1965
Colorado Governor Jared Polis, the Colorado Department of Transportation (CDOT), the Federal Highway Administration (FHWA), local officials and contractor Kiewit Corporation broke ground on October 19 on the I-270 Corridor Improvements project, a total investment of $806 million. The interstate runs east to west through Adams County and north Denver. Built in 1965, it is the only interstate in Colorado that has never received an upgrade, and it now carries more than 100,000 vehicles a day, more than it was designed for.
When complete, I-270 will have two general-purpose lanes and one new tolled Express Lane in each direction, with the Express Lane free for buses, motorcycles and carpools of three or more. The project will also replace 12 aging bridges built in the 1960s, rebuild the Vasquez Boulevard interchange, improve ramps at I-76, York Street and Quebec Street, and build a new pedestrian and bicycle bridge. Construction will occur in three phases: earthwork begins this fall, major bridge construction starts in spring 2027, the first phase is expected to conclude in early 2030, and the full project is expected to conclude in 2033.
"Every day, Coloradans count on I-270 to get to work, get home and keep goods moving. These improvements will make I-270 safer, more reliable, and faster for travelers, and will create good-paying jobs," Governor Polis said at the groundbreaking.
