Clark County's I-5 Bridge Crisis: $14.4 Billion & 20 Years of Disruption
Clark County's I-5 Bridge Crisis: $14.4 Billion & 20 Years of Disruption
Is the I-5 bridge being replaced? Yes. Cassandra Marks (Realtor Cas) breaks down the 2026 update on the Interstate Bridge Replacement (IBR) program. Key facts: The official cost has surged to $14.4 billion, construction is set for 2028–2045 (nearly 20 years), and pre-completion tolls will begin on the existing bridge as early as 2027. This guide covers the project's 108-year history, the CRC failure, the hidden internal estimate that sat in a file for months, the full toll math, and the financial impact on Clark County residents.
The I-5 bridge was built in 1917. Now, it's going to cost $14.4 billion to replace it — and you're going to start paying tolls on it by 2027. Hi, my name is Cassandra Marks, also known as Realtor Cas, and I'm a farmer with a wee little real estate problem.
As a transplant myself, I want to give you a complete, honest picture of what this project means for the people who live, work, and commute in Clark County. If you're evaluating the cost of living in Vancouver, WA vs Portland, OR, this bridge project is a central part of that equation.
Why Replacing This Bridge Has Taken Over 100 Years
Before 1917, crossing the Columbia River between Vancouver and Portland meant using a ferry. In winter, ice build-up made it incredibly dangerous. The turning point came in 1905, when nearly 2,000 people from Vancouver tried to cross for the Lewis and Clark Centennial World's Fair and nearly swamped the ferry system. Vancouver's mayor famously said that day: "We need a bridge."
It took over a decade of political fights, bond measures, and a governor's veto to make it happen.
The First Attempt: How $175 Million Simply Disappeared
In 2005, both states finally got serious with the Columbia River Crossing (CRC) project — a new bridge, light rail into Vancouver, rebuilt interchanges, tons of federal support. There was real momentum.
Over nine years, they spent $175 million. $105 million alone went to consultants, studies, and environmental impact statements. In 2011, the federal government gave it a green light. Then in 2013, the Washington State Senate killed it. The sticking point: they didn't want Portland's MAX Light Rail crossing into Washington. Without Washington's funding commitment, the whole thing collapsed.
Ten years, $175 million, zero bridges replaced, zero new lanes. The region started over — a decade older and a decade closer to the next earthquake.
The Second Attempt: The $14.4 Billion Reality Check
In 2019, both states formally launched the Interstate Bridge Replacement (IBR) program. Same fundamental problems, same two states, same basic scope. But a decade of delay comes with a massive price tag.
Nearly 20 Years of Active Construction (2028–2045)
Construction is expected to begin in 2028, and the full program could stretch to 2045. That is nearly 20 years of active disruption on the most critical transportation corridor in the Pacific Northwest.
During construction, freeway traffic through the project area will be rerouted five separate times as old structures come down and new ones go up. This is not a brief inconvenience. It's a multi-decade feature of life in this corridor.
What You'll Actually Pay: The Complete Numbers Starting 2027
The tolls are coming sooner than most people realize. Pre-completion tolling is expected to begin on the existing I-5 bridge as early as 2027 — before the new bridge is built, before construction has meaningfully begun. You will start paying tolls to cross the bridge that's already there.
The Official Studied Rate Range
The IBR program's official toll scenario study ranges from $1.55 to $4.70 per crossing with variable pricing by time of day. Peak commuter hours get the highest rates. These rates were modeled before the cost estimate jumped from $6 billion to $14.4 billion.
The Math on Even the Modest Scenario
| Commuter Type | Crossings / Week | At $4.70/crossing | Annual Cost |
|---|---|---|---|
| 5-Day Portland Commuter | 10 (round trip) | $47/week · $188/month | ~$2,256/yr |
| Family (4 Portland trips/month) | 8–10 trips | $37–$47/month | $450–$565/yr |
| Leisure crossings only (2–3×/month) | 4–6/month | $19–$28/month | $225–$340/yr |
| ⚠️ Worst-Case: $20/crossing commuter | 10 (round trip) | $200/week · $800/month | ~$9,600/yr |
The 77% Problem: Why Avoiding the Toll Won't Help Either
When tolls arrive, a lot of people will try to avoid them by switching to I-205. Here's the hard data on why that strategy hurts everyone — including the people who choose to avoid the toll.
A 2012 survey found that 77% of Clark County drivers said they would divert to I-205 if I-5 started charging tolls.
If even half of those drivers follow through, I-205 absorbs that volume on top of all the existing construction-era overflow. The free crossing gets slower, less reliable, and more congested for everyone. Whether you pay the toll or go around it, you're paying — either in dollars or in time.
Why There Is No Real Substitute for I-5
People always ask: what are your other options when I-5 and I-205 are both backed up? Here's the honest answer.
Moving to Clark County? Here's What to Know
This isn't just a commuter problem. Portland is Clark County's backyard. The bridge isn't just about people driving to work — it's about everyone in Clark County who has a life south of the river. Blazers games, concerts, Timbers matches, OHSU for major medical, PDX airport. Right now, all of that is 20–30 minutes away. That changes once construction begins in 2028.
