Its been almost one year since Baltimores Francis Scott Key Bridge collapsed into the frigid Patapsco River after a cargo ship owned and operated by DALI crashed into it, killing six construction workers. Kiewit Infrastructure Corporation was awarded a $73 million contract to design and build the Francis Scott Key Bridge replacement last September, as reported by AN.This week, Governor Wes Moore and the Maryland Department of Transportation (DOT) unveiled Kiewits design for the replacement bridge. Maryland Lieutenant Governor Aruna K. Miller called the design a pillar of engineering and transportation brilliance that will stand watch over the harbor, connecting Marylanders to opportunities and welcoming commerce into our port. The new bridge will continue to serve as a vital connector for the I-695 Baltimore Beltway across the Patapsco River. It will have far greater vertical and horizontal clearances than the 1970s structure, a steel arch continuous truss bridge, Maryland State officials said. The wider expanses between pylons will give cargo ships more room for ease of passage.Renderings of the new Francis Scott Key Bridge show a cable-stayed bridge supported by pylons. The two main bridge towers, where ships will go through, will be more than 1,600 feet apart from one another. The bridge deck height will be about 230 feet above the main deep-draft shipping channel. It is designed to last for 100 years.The bridge towers will be 600 feet tall, and the cable-stayed main spans total length will exceed 3,300 feet.

There will be two 12-foot-wide lanes in each direction, 10-foot-wide outside shoulders, and 4-foot-wide inside shoulders per direction of travel. The bridge towers will be 600 feet tall, and the cable-stayed main spans total length will exceed 3,300 feet. Congressman Kweisi Mfume said to get to this point took unified front across all three levels of government. Baltimore Mayor Brandon Scott said the design by Kiewita company based in Omaha, Nebraskais a symbol of beauty that is poised to serve as a vital connector for our city to the world and a reminder of those we lost.Moving forward, the project will exit the design concept phase and inch toward a final design and regulatory approvals before initiating construction.The future bridges non-structural design elements, Maryland State officials shared, will be informed by thousands of Marylanders through forums and community updates. This is meant to ensure the new Francis Scott Key Bridge resonates with Marylanders.Governor Moore noted that the State of Maryland continues to pursue DALI for damages. Maryland officials want DALI to pay for Francis Scott Key Bridges reconstruction, and for all parties responsible for the tragedy to pay damages.
