The bridge across the Patapsco River collapsed after a container ship struck one of its piers, killing six members of a roadway maintenance crew who were working on the structure at the time.

Kiewit has won a $73 million phase one contract as the progressive design-builder for the replacement bridge that carries the I-695 highway over the river.

Construction is set to start in 2025 for completion in the autumn of 2028, following the Maryland Transportation Authority’s (MDTA) decision to award the contract to Kiewit.

The progressive design-build process brings on board a project delivery team under one entity and a single contract to provide both design and construction services.

The MDTA said it would work to foster collaboration among the project team, local communities and stakeholders, ensuring open communication and inclusive partnership opportunities, particularly for small and disadvantaged businesses.

It noted that the scope of the project and accelerated timeline will require a “substantial amount of skilled labour” to complete the construction expeditiously, safely and reliably.

Upon successful completion of Phase 1, Kiewit will have exclusive negotiating rights for Phase 2, which includes project final design/engineering and construction, estimated at a total cost of $1.2 billion. In the event a guaranteed maximum price is not agreed upon, the MDTA will deliver the work under a separate contracting mechanism.

The MDTA released a Request for Proposals (RFP) in July for the General Engineering Consultant, who will serve as MDTA’s engineering representative for the Rebuild. The MDTA expects to award the $75 million contract in January 2025.

In July, the Federal Highway Administration issued a Categorical Exclusion classification and National Environmental Policy Act approval for the I-695 Francis Scott Key Bridge Rebuild Project. The federal agency that because the replacement bridge will be within the former bridge’s right-of-way and have the same capacity of four travel lanes, it is not anticipated to significantly impact community, natural or cultural resources.
