In a groundbreaking approach to modernize roadside rest areas (SRRAs), the John “Chuck” Erreca Rest Area Replacement Project on Interstate 5 in California is making waves with its emphasis on sustainable infrastructure writes Mark Gudenas and Kristin Dizpensa for Roads&Bridges. This $37 million endeavor, led by the Caltrans District 10 construction team and Walsh Construction Company, showcases a forward-thinking commitment to eco-conscious practices, with a spotlight on the strategic choice of concrete pavement.
As the backbone of the project’s pavement, concrete emerges as a durable and low-maintenance solution, aligning seamlessly with the rest area’s long-term sustainability goals. Over 180,000 cubic feet of concrete was employed for parking spaces, with 9-inch-thick jointed plain concrete pavement (JPCP) for cars and 12-inch-thick JPCP for trucks. The decision to use concrete extends beyond its longevity, as it proves resistant to the challenges posed by heavy traffic, California’s temperatures, and potential oil drips from large trucks.
Concrete’s environmental benefits take center stage, contributing to the rest area’s overall sustainability. Its high albedo, reflecting significant light energy back into the atmosphere, aids in reducing ambient air temperatures, countering the urban heat island effect. Moreover, the material’s resilience to oil drips not only lowers maintenance costs but also enhances the visitor experience at the rest area.
In a holistic sustainability effort, Caltrans upgraded utilities, focusing on low-water usage and low-power demand. The rest area’s wastewater facility captures and treats gray water for reuse in flushing toilets, reducing reliance on the state water system during drought periods. Landscaping choices further minimize water use by incorporating indigenous, drought-tolerant plants.
The John “Chuck” Erreca Rest Area stands as a testament to the integration of design, history, and environmental consciousness. With graphics honoring the region’s Basque history and a plaza design inspired by aerial views of farmland, the rest area pays homage to its roots while embracing a sustainable future. As this project nears completion with a projected opening in September, its innovative use of concrete pavement sets a benchmark for the development of eco-friendly rest areas across the nation.
