The End of the “Rough Road” in Southwest Washington

If you drive in Southwest Washington, you’ve seen the signs.

Rough Roads.
Slower speeds.
A bumpy ride.

In Clark County, two stretches along Interstate 5 and State Route 14 have “Rough Road” signs displayed. Years of increased traffic, aging pavement and tough weather have taken a toll. The result: cracked surfaces, potholes and temporary fixes.

But that’s about to change.

Both locations are getting the long-term attention they need this summer, leading to smoother, safer trips.

Like many preservation projects across the state, these improvements depend on available funding, which means we often have to prioritize the most urgent needs first and fix them in phases. Now, it’s time for these two highways to finally get their turn.

A smoother ride on SR 14

For years, drivers crossing the SR 14 West Camas Slough bridge have felt the wear and tear firsthand. Potholes and ruts keep coming back, making each trip a bumpy one.

Maintenance crews have stayed busy patching and making repairs as needed, but those fixes have always been temporary. Until now.

In summer 2026, crews will begin a full resurfacing project on the bridge.

The work includes:

• Removing old asphalt
• Inspecting and repairing the concrete deck
• Adding a new waterproofing layer
• Paving new asphalt
• Replacing four expansion joints

When the work is finished, travelers can expect a smoother, more reliable crossing with fewer maintenance closures. No more dodging potholes that kept bouncing back.

Taking a new approach on I-5

Another rough stretch lies on southbound I-5 that many drivers know all too well.

Between Northeast 179th Street and the I-5/I-205 split, thousands of concrete panels have carried traffic for decades, well beyond their intended lifespan. Many panels are broken and uneven, creating a rough and bumpy drive.

Concrete must be flat before it can be paved over. Simply adding asphalt on top won’t fix the problem. Over the last several years we’ve replaced the worst panels, but there’s just too many to repair one by one.

Now, we’re trying something different.

In summer 2026, crews will use a method called “crack, seat and overlay” to rebuild the roadway.

Here’s how it works:

• The old concrete is cracked into smaller pieces.
• Those pieces are pressed down firmly into place.
• Several layers of asphalt are added on top.

This method allows us to repair a larger stretch of highway quickly while keeping costs down.

But the work doesn’t stop there. Crews will also address the stretch of I-5 just north of the crack, seat, and overlay work, between NE 179th Street and Ridgefield. First, this summer, crews will replace the worst of the worst panels, and then in 2027 return to complete the full crack, seat, and overlay work. There’s more to come and smoother rides ahead.

The road to smooth ahead

When these projects wrap up at, those familiar “Rough Road” signs will disappear.

We know these roads are part of your daily routine. Whether you’re commuting to work, moving goods, taking a road trip, or running errands, every trip matters.

We appreciate everyone’s patience as we make these improvements. We can’t wait to put the bumps behind us and look forward to smoother roads ahead.
