The main steel beam of the Dongying Yellow River Road-Rail Bridge, a key control project of the Tianjin-Weifang High Speed Railway, was recently completed, laying the foundation for subsequent track-laying and operation. The Dongying Yellow River Road-Rail Bridge is built in a combined road-and-rail mode, with a total length of 2,230.4 meters and a main span of 600 meters, known as the "First Span of the Yellow River." Once opened, the bridge will greatly facilitate travel for residents on both sides of the Yellow River and will play an important role in promoting the development of the efficient ecological economic zone of the Yellow River Delta, advancing regional economic and social coordination, and improving China’s comprehensive transportation system.
