What Is the Current Status of the Francis Scott Key Bridge Rebuild?

The Francis Scott Key Bridge, which collapsed on March 26, 2024, after being struck by the container ship Dali, is being rebuilt through a multi-year project led by the Maryland Department of Transportation (MDOT). A temporary replacement structure opened to traffic in May 2024, while design and permitting for the permanent bridge continues under MDOT oversight, with construction expected to begin in 2025 and completion targeted for 2028.

Background on the Collapse

On the morning of March 26, 2024, the Dali lost power while departing the Port of Baltimore and struck one of the bridge's main support columns. The impact caused the span to collapse in approximately 90 seconds, killing six workers and disrupting traffic, cargo movement, and regional commerce. The bridge, completed in 1977 and carrying roughly 11,000 vehicles daily across the Inner Harbor, connected Fells Point to Canton and was the only direct vehicle crossing over that stretch of the harbor.

The collapse immediately closed all routes connecting the eastern and western sides of the harbor in that area, forcing drivers to take detours through downtown Baltimore or use the Harbor Tunnel, a toll crossing two miles south. The Harbor Tunnel saw traffic volume increase to roughly double its normal capacity in the weeks following the collapse.

The Temporary Bridge Solution

Within weeks, MDOT began construction on a temporary replacement structure. This interim bridge, which opened to traffic on May 30, 2024, was designed to accommodate the volume displaced by the collapse while the permanent structure underwent planning and permitting. The temporary bridge is not a single-span structure like the original but consists of multiple shorter spans that allow river traffic to continue underneath.

The temporary bridge reduced but did not eliminate congestion. Peak-hour travel times across it have averaged 15 to 25 minutes, compared to 3 to 5 minutes before the collapse. The structure is expected to remain in place for approximately three to four years, depending on the permanent bridge's construction schedule.

Permanent Rebuild Plans

MDOT selected a design team in late 2024 to develop the replacement bridge. The permanent structure is being designed to accommodate current traffic loads plus future growth, with input from the Port of Baltimore, the Army Corps of Engineers (which regulates the navigable waterway), and the Federal Highway Administration. The design phase typically requires 18 to 24 months for a structure of this complexity.

Key design considerations include span height to ensure cargo ships can pass underneath (the original bridge had an air draft of 185 feet at mean high water), placement of support columns to minimize river obstruction, and resilience against future vessel strikes. The new design is expected to incorporate protective measures such as dolphins (fixed structures that absorb ship impacts) around support columns, a feature absent from the original bridge.

Permitting involves review by federal agencies including the Army Corps of Engineers and the National Oceanic and Atmospheric Administration, as well as state environmental agencies. This process typically takes 12 to 18 months for major infrastructure projects in Maryland.

Funding and Responsibility

President Joe Biden announced federal emergency aid in March 2024, and Congress allocated $60 million in emergency supplemental funding to support the temporary bridge and initial rebuild planning. The federal government has indicated it will cover the full rebuild cost, breaking from the typical cost-sharing arrangement where states contribute to bridge reconstruction. This commitment reflects the national significance of the Port of Baltimore and the disruption to East Coast commerce caused by the closure.

MDOT is managing the project with oversight from the Governor's office and coordination with port stakeholders and federal agencies. Regular project updates are published on MDOT's website, which contains timelines and design progress reports.

Port and Regional Impact

The Port of Baltimore handles about 750,000 Twenty-foot Equivalent Units (TEUs) of cargo annually and is the leading port on the East Coast for importing automobiles, exporting coal, and handling heavy machinery. The bridge closure disrupted rail connections to the port, reduced barge traffic capacity, and forced shipping routes to divert through Hampton Roads, Virginia, adding cost and delay to freight movement.

Reopening the temporary bridge recovered most port functionality, though crane-equipped container berths remained limited. The full return to pre-collapse capacity is expected only when the permanent bridge reopens.

Timeline Expectations

Current projections call for the permanent bridge to enter construction in late 2025 or early 2026, with completion in 2027 or 2028. This schedule assumes permitting proceeds on the standard federal and state timeline. Any environmental challenges, design modifications, or supply chain delays for specialized materials could extend the schedule.
