Sustainable transportation infrastructure isn’t a buzzword—it’s a smarter, safer, and more cost-effective way to build Idaho’s future. And after the recent landslide on U.S. Highway 95, it’s clear: resilient, environmentally sound roadways aren’t optional—they’re essential.

At Pathways Forward Idaho, we believe transportation planning should reflect our values: protecting wildlife, preserving natural resources, and preventing disasters before they happen. So how much do you know about sustainable infrastructure? Take this quick quiz and find out.

True or False? Test Your Knowledge of Sustainable Transportation Infrastructure

1. Using recycled asphalt leads to weaker road construction.

False.

Reclaimed Asphalt Pavement (RAP) is widely used in sustainable transportation infrastructure and performs just as well as new materials. It’s the most recycled product in America’s construction industry—reducing costs, emissions, and landfill waste.

2. Permeable pavement improves Idaho’s water quality.

True.

Permeable pavement allows rainwater to soak into the ground rather than run off into storm drains—reducing erosion and filtering pollutants. In sustainable transportation infrastructure, this design supports Idaho’s groundwater recharge and protects rivers and farmland.

3. The recent Highway 95 landslide was a fluke with little long-term impact.

False.

The landslide between Council and New Meadows shut down U.S. Highway 95, Idaho’s most critical north-south route. It disrupted commerce, emergency services, and everyday travel. This incident highlights why sustainable transportation infrastructure must include slope stabilization, water management, and climate resilience.

4. Wildlife crossings don’t really impact road safety.

False.

Sustainable transportation infrastructure prioritizes safety for both people and wildlife. Overpasses and underpasses in places like Colorado have cut wildlife-vehicle collisions by over 80%. Idaho’s own migration corridors would benefit from similar features.

5. Sustainable road design always costs more.

False.

Upfront costs may be higher, but sustainable designs save money over time by reducing repairs, minimizing flood damage, and increasing road lifespan. Bioswales, recycled materials, and smart water systems are all part of a longer-term, lower-cost solution.

Why Sustainable Transportation Infrastructure Matters in Idaho

Sustainable infrastructure isn’t just about green materials—it’s about building roads that last, protecting ecosystems, and serving Idaho’s people and economy.

At Pathways Forward Idaho, we advocate for infrastructure solutions that:

• Use recycled asphalt, concrete, and low-emission materials
• Reduce runoff and erosion with stormwater-smart designs
• Integrate wildlife crossings and habitat protection
• Stabilize terrain to prevent landslides and road washouts
• Reflect Idaho’s long-term values of conservation and safety

These aren’t just ideas—they’re essential upgrades for a growing state.

What You Can Do to Support Smarter Infrastructure

Strong, resilient roads benefit every Idahoan—but change starts with action. Here’s how you can support sustainable transportation infrastructure in your community:

• Stay informed about road projects and funding initiatives
• Ask questions: How are sustainability and environmental risks being addressed?
• Support leaders who prioritize infrastructure that works with—not against—our natural environment
• Join Pathways Forward Idaho in advocating for smarter, more resilient transportation investments

The Road Ahead

The Highway 95 landslide is just one example of why Idaho must evolve its approach to infrastructure. With thoughtful planning and smart investment, we can reduce risk, preserve natural beauty, and build a future where growth doesn’t come at the cost of the environment.

Sustainable transportation infrastructure isn’t just a goal—it’s the path forward.
