【京津冀首条跨省地铁线路 年底基本具备开通条件】
Construction of the main road network of Beijing’s Tongzhou District is progressing rapidly. The 660 kilometer network of roads is expected to serve as the backbone of the city’s Sub-center transportation system. By the end of this year, subway Line 22 (Pinggu Line) will be ready for operation, becoming the first inter-provincial subway line in the Beijing-Tianjin-Hebei region.

北京市通州区“十一横九纵”骨干路网已基本成型，城市副中心道路总里程突破660公里。今年年底地铁22号线（平谷线）基本具备开通条件，将成为京津冀首条跨省地铁。
