Tianjin starts to build street overpass bridges in downtown area, critical junctions and bus stops. The overpass connecting Fuan Avenue and Heping Road as well as the one crossing Dongxing Road section of middle ring line has been under construction. Four more overpass bridges will start to build recently at Changjiang Road in Nankai District, Weidi Road, Qinjian Road and Hongqi Road section of middle ring line. The bridges will be safer for people to cross the streets and make an improvement for the traffic.
