On May 29, the Tieshan Bridge, a public railway interchange at the entrance of the second railway in Jiabei, North Xinhua Road, was lifted and opened to traffic. In the way of "flat reform", the project effectively solved the traffic congestion caused by the cross-pass of the second railway in Jiabei due to highway and railway, and played a great role in further optimizing and upgrading the transportation conditions of Jiabei Industrial Park.
