EDGEMERE, Md. — Officials updated the cost estimate for the Key Bridge rebuild and pushed the estimated timeline back on Monday.

The announcement came on the eve of a National Transportation Safety Board hearing on the Key Bridge collapse that is expected to settle a cause for the 2024 collapse that killed six construction workers.

In a news release, the Maryland Transportation Authority said the cost will likely be anywhere from $4.3 billion to $5.2 billion. The change marks a stark contrast after the Associated Press reported in May 2024 that the initial cost was estimated to be between $1.7 billion and $1.9 billion.

"That was a 0% design. We had no engineering for a new bridge. We hadn't done any studies in the river," said Bruce Gartner, executive director of the MDTA. "You need to give the federal government an estimate to enter into the emergency relief program."

After initially saying the new bridge should be reopened by fall 2028, officials revised the estimated opening date to be in late 2030.
