The estimated cost to replace the Interstate 5 Bridge connecting Vancouver, Washington and Portland, Oregon has doubled to between $13.5 billion and $15.2 billion, according to officials overseeing the project. Despite the ballooning price tag, the governor of Washington has vowed to move forward with the bridge replacement, stating 'we're going to build this bridge' and that the state has the resources and commitment to make it happen.

Why it matters

The I-5 Bridge is a critical transportation link between Washington and Oregon, and its replacement has been a long-standing priority for regional leaders. However, the dramatic increase in projected costs has raised concerns about the project's viability and the impact on taxpayers. The governor's commitment to proceed signals the importance of the bridge replacement, but also highlights the need for effective cost management and transparency throughout the process.

The details

Program officials confirmed this week that the estimated cost of the I-5 Bridge replacement project has doubled from the previous range of $5 billion to $7.5 billion to a new estimate of $13.5 billion to $15.2 billion. This significant increase in projected costs has raised questions about the project's feasibility and the ability to secure the necessary funding. Despite the escalating price tag, Washington Governor Bob Ferguson stated that the state is 'committed to making this happen' and that 'we have the resources' to move the project forward.
