| 摘要： | It was built in 1889, and we're celebrating this reconstruction project because it's an achievement in engineering and construction. The price tag - $222 million - goes to show the complexity of the project and the importance of the bridge to the region's infrastructure. The Merchants Memorial Bridge crosses the Mississippi River between St. Louis and Venice, Illinois, and due to maintenance, safety, and capacity issues, the Terminal Railroad Association of St Louis (TRRA) replaced the original Pennsylvania truss spans with wider, safer, and stouter steel truss spans. The bridge's location over the Mississippi River contributed to the challenging project, according to Daniel Sieve, senior project manager from Walsh Construction. "The river's flow is unrestricted below the Missouri River allowing the river to rise and fall quickly, which requires the necessity to plan for multiple water elevations for many activities," Sieve said. |
