The Concourse E project at Baltimore-Washington International Thurgood Marshall Airport converted an existing stormwater management pond into a parking area for commercial airline and commuter aircraft.

This 193,200-sq-ft high school is a fitting successor, the team says, to a locally cherished, historically significant facility that no longer supported the needs of contemporary education.

The circular 23,500-sq-ft child development center emphasizes sustainability in ways beyond its large windows, intricate landscaping and extensive use of natural interior finishes, the team says.

The project team says technology played a central role in the $68.3-million plan to construct five dual bridges within an 11-mile section of the planned 1,500-mile Continental 1 international trade corridor, connecting Canada with Florida.

Converting the functionally obsolete cloverleaf interchange connecting I-70 and U.S. Route 19 into Pennsylvania’s first diverging diamond interchange required a traffic control plan to minimize disruptions to the tens of thousands of motorists who travel through the area daily.

The project called for a major traffic change, replacing a congested signal-controlled intersection in a primary commercial corridor with a three-lane roundabout.
