Interstate Bridge Replacement: Vancouver Commute Impact

How will the Interstate Bridge Replacement Project affect Vancouver commutes and property values?

The Interstate Bridge Replacement (IBR) Program received its Amended Record of Decision on July 1, 2026, clearing the way for construction-related activities. Construction is anticipated to begin in 2028 and will take six to seven years to complete. For Vancouver residents, that means a prolonged period of planning, staged disruption, and ultimately a transformed I-5 corridor connecting Clark County to Portland.

Where the Project Stands Right Now

This is not a distant proposal anymore. As of August 2026, the IBR Program is actively moving through pre-construction procurement. According to the IBR Program's federal approval announcement, the program will proceed with a first funded construction phase backed by $5.7 billion in local, state, and federal funding.

The program is preparing to issue a request for qualifications in 2026, followed by a request for proposals later this year, with a contractor expected to be hired in 2027. Per the IBR Program's next steps page, construction is then anticipated to begin in 2028 and run for six to seven years.

The City of Vancouver notes that the Final Supplemental Environmental Impact Statement was published on April 17, 2026, and that the program updated its cost estimate in March 2026 to reflect national construction cost inflation, an extended timeline, and updated construction sequencing requirements. Those two milestones are the clearest markers that the project has crossed from planning into execution mode.

What the New Bridge Will Actually Look Like

The IBR Program FAQ describes the replacement as a fixed-span bridge with 116 feet of vertical navigation clearance. That single design choice matters enormously for daily commuters: it eliminates the routine bridge lifts that currently cause unpredictable delays on I-5. Anyone who has sat in backed-up traffic while the existing lift bridge opens for river traffic knows exactly what that's worth.

The same FAQ confirms that the existing bridge will remain open until the new bridges are complete. That's actually good news for the construction period, Vancouver residents won't face a full closure. The more realistic challenge will be staged lane reductions and construction-zone congestion over the multi-year build window.

Tolling Is Coming

The IBR FAQ is direct about this: tolls will be used to pay for construction, maintenance, and operation of the facility and to help improve travel reliability in the corridor. Decisions on rate setting, exemptions, and discounts rest with the Oregon and Washington transportation commissions, meaning the specific numbers aren't set yet, but the mechanism is confirmed.

For daily commuters crossing into Portland for work, tolling will be a real budget consideration. I always tell relocating buyers to factor in bridge traffic and commute realities before choosing where to live in Clark County, and now that conversation has to include a future toll line item. Whether you're looking at a home in Vancouver's waterfront district or further out in Battle Ground or Ridgefield, the commute math is about to change.

The Light Rail Question: Waterfront or Library Square?

Light rail is included in the current IBR plan, but where it actually ends inside Vancouver is still being debated. The IBR Program's current plan has light rail terminating at Vancouver's waterfront. However, a July 2026 report from The Columbian shows that Clark County Council members unanimously supported extending light rail further to Vancouver's Library Square, a more central destination that would serve a broader slice of the city.

The gap between those two endpoints isn't just geography. It's the difference between transit access that serves the waterfront and transit access that anchors downtown Vancouver as a genuine urban core. The funding gap is the obstacle, and whether it gets bridged (no pun intended) will meaningfully affect which Vancouver neighborhoods see the strongest long-term transit-driven demand.

If you're considering a purchase near Downtown Vancouver or the waterfront and transit access factors into your decision, this is worth tracking closely. It's the kind of detail I walk my clients through before we even start touring homes, because where you land relative to future infrastructure can shape your daily life for decades.

What This Means for Clark County Property Values

Infrastructure investment of this scale doesn't move markets overnight, but it does shift the long-term calculus for buyers and sellers across the region. Here's how I'm thinking about it for different parts of Clark County.

Near-Term: Construction Disruption

The six-to-seven-year build window starting in 2028 will create real commute friction on and around I-5. Areas that depend heavily on I-5 access to Portland, including parts of Vancouver closest to the bridge, may see some buyers hesitate during peak construction years. That's a short-term dynamic, not a structural one.

Long-Term: Improved Connectivity

A fixed-span bridge with no lift delays, light rail access, and a rebuilt I-5 corridor is a meaningful upgrade to the region's infrastructure. Historically, major transit and bridge improvements tend to support property values in areas that gain direct access. The specific impact on any individual home depends on condition, location relative to the corridor, and broader market conditions at the time.

Recent Zillow market data shows the Vancouver area median sale price at $530,000, with homes spending a median of 14 days on market. That pace reflects demand that's already strong. The IBR project adds a longer-horizon reason for out-of-state buyers, particularly those relocating from Portland, to look seriously at Clark County, especially given Washington's lack of a state income tax.

For a fuller picture of where different parts of Clark County stand today, here's the current area-level market snapshot:

According to Redfin's Clark County housing market data, the median sale price for the county was $549,000 in February 2026, up 2.6% year over year. That's a useful baseline as the IBR project's pre-construction phase unfolds.

If you're weighing which Clark County community makes sense for your situation, whether that's proximity to the bridge corridor, access to future light rail, or simply finding the right price point, that's exactly the kind of conversation I have with buyers before they start searching. You can also dig into the Vancouver, WA housing market reality check I published in July 2026 for a broader look at where the market stands.

For out-of-state buyers thinking about relocating to the region, the step-by-step guide to buying in Vancouver from out of state walks through the full process, including how to evaluate commute corridors before you ever visit in person.

The IBR project is one of the biggest infrastructure stories in the Pacific Northwest right now, and it will reshape how people think about living in Clark County for years to come. Your specific situation, what you own, where you're looking, and your timeline, determines how it affects you. That's where a local perspective makes the difference.

Frequently Asked Questions

When is construction on the Interstate Bridge Replacement Project expected to start?

According to the IBR Program's next steps page, construction is anticipated to begin in 2028. The program is currently in pre-construction procurement, with a request for qualifications expected in 2026, a request for proposals to follow, and a contractor anticipated to be hired in 2027.

How long will the Interstate Bridge Replacement Project take to build?

The IBR Program estimates the build will take six to seven years once construction begins. With a 2028 start, that puts substantial completion somewhere in the mid-2030s, though sequencing and funding can affect the timeline. The existing bridge will remain open throughout construction.

Will the new Interstate Bridge be tolled, and who decides the toll rates?

Yes, tolling is confirmed as part of the IBR Program's funding model. According to the IBR FAQ, tolls will cover construction, maintenance, and operations. Rate setting, exemptions, and discount decisions rest with the Oregon and Washington transportation commissions, specific rates have not been set yet.

Will the existing Interstate Bridge stay open during construction?

Yes. The IBR Program FAQ confirms the existing bridge will remain open until the new bridges are complete. Commuters should expect staged construction impacts and possible lane reductions over the multi-year build period, but a full closure is not the current plan.

Is light rail planned to reach downtown Vancouver or only the waterfront?

The IBR Program's current funded plan has light rail ending at Vancouver's waterfront. However, as of July 2026, Clark County Council members unanimously supported extending light rail further to Library Square in downtown Vancouver, per The Columbian. A funding gap currently stands between the waterfront terminus and the Library Square extension, so the final alignment is not yet resolved.

What is the latest official status of the Interstate Bridge Replacement Project?

As of August 2026, the IBR Program received its Amended Record of Decision on July 1, 2026, authorizing movement into construction-related activities. The City of Vancouver notes the Final Supplemental Environmental Impact Statement was published April 17, 2026, and the program updated its cost estimate in March 2026. Pre-construction procurement is actively underway.
