10号州际公路凤凰城南段第三期扩建动工 双向拓至三车道
亚利桑那州交通部近日在凤凰城以南的"野马山口"（Wild Horse Pass）项目第三期工程破土动工，继续拓宽车流量极大的10号州际公路，以提升通行能力与行车安全。
第三期工程覆盖凤凰城以南约11英里路段，穿过希拉河印第安社区。工程内容包括：10号州际公路双向拓宽至各三车道；在202环线至里格斯路段区间双向各新增一条共乘车道；重建野马山口大道、里格斯路、皇后溪路/347号州道三处互通立交；并在科利路新建一处互通立交。
《亚利桑那共和报》此前的调查曾指出，该路段是跨越中央隔离带撞车事故的高发区，拓宽与立交改造有望缓解这一安全隐患。亚利桑那州交通部表示，10号州际公路是连接凤凰城与图森及加州的主要货运与通勤走廊，日均车流量巨大，扩建完成后将显著改善早晚高峰拥堵。目前工程已进入施工阶段，交通部提醒过往司机注意施工区限速与车道变化。
Phase Three of I-10 Widening South of Phoenix Breaks Ground; Highway to Grow to Three Lanes Each Way
The Arizona Department of Transportation has broken ground on phase three of the Wild Horse Pass project south of Phoenix, continuing the widening of the heavily traveled Interstate 10 to improve capacity and safety.
Phase three covers about 11 miles south of Phoenix through the Gila River Indian Community. The work will widen I-10 to three lanes in each direction, add one HOV lane each way between Loop 202 and Riggs Road, rebuild the interchanges at Wild Horse Pass Boulevard, Riggs Road and Queen Creek Road/State Route 347, and build a new interchange at Koli Road.
An earlier Arizona Republic investigation identified the segment as a hotspot for cross-median crashes, and the widening and interchange rebuilds are expected to ease that safety risk. ADOT says I-10 is a primary freight and commuter corridor linking Phoenix with Tucson and California, carrying heavy daily volumes; once complete, the project should significantly improve rush-hour congestion. Construction is under way, and ADOT urges drivers to observe work-zone speed limits and lane changes.
