What is the Baltimore Key Bridge daily traffic volume/average daily traffic?

The Francis Scott Key Bridge was a monument to modern engineering, stretching across the Baltimore Harbor and its bustling shipping channels. Its steel truss cantilever arch main spans and plate girder approach spans contributed to a total length of 8,636 feet, equivalent to 1.6 miles.

Among its notable features, the bridge boasted a continuous truss length of 2,644 feet, with the main span extending a remarkable 1,200 feet and the back span measuring 722 feet. This architectural marvel offered a vertical navigational clearance of 185 feet beneath its main span, ensuring unimpeded maritime traffic passage until last night.

Built to Interstate highway standards, the Francis Scott Key Bridge was a vital component of the freeway system. It was explicitly designated as part of Interstate I-695, commonly known as the Baltimore Beltway. This strategic placement facilitated efficient travel and seamless connectivity for commuters and travelers alike.

The bridge spanning the Baltimore Harbor and shipping channels was a vital connection for communities and transporting goods and people across waterways. It had four lanes and a speed limit of 55 mph, ensuring smooth traffic flow while adhering to safety standards. The bridge carried an estimated 11.5 million vehicles annually, with an average daily traffic of 31,500 vehicles. It served as a Baltimore lifeline until last night.
