Soaring costs and delays renew debate over I-5 Bridge replacement
The Interstate 5 Bridge replacement is now expected to cost up to $10 billion, with final environmental approvals delayed until 2026 and construction possibly not beginning until 2032 or later. Lawmakers in Washington and Oregon are divided — some remain committed to completing the full project, while others argue it has spiraled into a costly “boondoggle” that should be dramatically scaled back or even ended. This week’s poll asks whether you think lawmakers should consider pulling the plug on the project.

Dump light rail. It is an extravagant waste that more than doubles if not triples the cost of the project. Four lanes both directions, if not five depending on how SR14, Tomahawk Island, and Hayden Island interchanges fit in (the current ramps and marge points are a joke). The span must include space and height for existing river traffic and future growth. Keep the design simple. Otherwise, to hell with it.
Loot rail has got to go. Trimet just announced a $300 Million hole in their budget, mainly because ridership has dropped so much. They are saying that they may have to cut service on the Green Line as early as 2027, and service cuts to several bus lines as soon as this November. Attempting to partner with any failing transit agency like C-Tran is attempting to do via the IBR is financial suicide.
It is astounding that the spending on this effort is rapidly approaching what the failed CCP spent, with exactly the same results. Time to cut our losses once and for all. Vancouver & Clark County cannot afford our equivalent to Boston’s “Big Dig”.
These people will have spent their entire careers on this project and solved nothing except to collect their PERS pension. We have the wrong group working this boondoggle from CRC to IBR to ???!
