STRETCHING OVER WATERWAYS, roads and greenspaces, rail bridges are critical links in railroads' systems. Many of the structures across the country have reached or exceeded their lifes-pans - with some in place for a century or more - so they require major upgrades or replacement. Efforts to preserve or modernize those crucial links mean freight and passenger railroads collectively spend hundreds of millions of dollars annually on bridge work. Their contractors and crews remain busy performing structural overhauls, building new structures or conducting routine maintenance to ensure bridges remain safe and sound. Following are a few rail bridge projects that captured the attention of one Class I, two short lines and two commuter railroads last year. The projects either entered the planning stages, advanced to construction or were completed in 2020.
