Falcons in the Field

Working in the field means being prepared for any safety challenge that could arise… including the Peregrine Falcon. Once an endangered species, Peregrines are an unexpected, yet majestic visitor who have made themselves at home on many bridges. Mike Januszkiewicz, Assistant Director of Field Services, explains why these birds choose bridges for nesting, the dangers to prepare for, and the fun of exploring nest cams.

Transportation Management Plans - The Critical Path to a Successful Project

A complex highway or bridge replacement project can have significant impacts on a community that extend well beyond the work zone. The Transportation Management Plan (TMP) process, which is required on federally funded projects, has focused time, attention, as well as investment to accommodate motorists, and more recently bicyclists and pedestrians during construction.

Bridge Coatings: More Than Just a Color

Have you ever thought about the coating on a bridge? Wondered if it’s paint just like you’d use for your house, or if it’s painted simply to give the bridge some color? The paint on a bridge is, in fact, essential to the integrity and lifespan of the bridge.  Just as you use clothing and sunscreen to combat the sun and other weather conditions, bridge coating systems help protect our nation’s bridges, ensuring their longevity.

Replacing an Icon

Since 1852, the Portage Viaduct has carried a rail line across the Genesee River Gorge, near the town of Portageville, NY. First made of timber, then replaced with a wrought iron structure , the crossing became an icon for the community. Tasked with replacing the viaduct, Modjeski and Masters worked with the community and the Norfolk Southern Railway Co. to create a new iconic arch bridge for the gorge.
