Interstate Bridge project cost estimates soar up to $17.7B – Daily Journal of Commerce

The Interstate Bridge replacement project between Vancouver, Washington and Portland has seen its cost estimates more than double to $17.7 billion, raising concerns about funding. The U.S. Coast Guard approved a fixed-span design, but the high costs have complicated the project's outlook. The Oregon Department of Transportation is expected to release a final cost estimate in March, with ongoing state and federal funding sources likely needed to complete the project.
