When will Tiantongyuan East Area 1 cross Qinghe Bridge open to traffic?

It's already open to traffic. By June 26, 2023, the bridge across the Qinghe River in Tiantongyuan East District has been completed and opened to traffic on September 6, 2022. The crossing of Qinghe Bridge in the east of Tiantongyuan can improve the road network structure in the south of Changping District, increase the density of horizontal connecting lines between Huilongguan and Tiantongyuan, and the new Qinghe Bridge can break through the broken road and realize the north-south connection between Chaoyang and Changping District.
