    Discover more about Donner Summit Bridge

    The Donner Summit Bridge, often called the Rainbow Bridge, stands as a proud monument to early 20th-century engineering and a testament to the enduring spirit of the Donner Summit community. Spanning Donner Pass on what was once US Route 40, this iconic concrete arch bridge offers visitors a unique blend of historical significance, architectural beauty, and breathtaking views of the surrounding Sierra Nevada landscape. Completed in 1926, the Donner Summit Bridge was a groundbreaking achievement in highway construction. As automobile travel gained popularity, the steep grades of the original Donner Pass road proved challenging for vehicles. The California state government sought a solution, and the result was a bridge designed with both a curve and a gradual incline – a revolutionary concept at the time. This innovative design not only eased the passage for automobiles but also created a visually striking structure that has captivated travelers for nearly a century. The bridge's construction was a significant undertaking, with materials sourced from nearby Donner Lake. The project cost $37,304.32, a considerable sum in the 1920s, and was hailed as a triumph of engineering. For decades, the Donner Summit Bridge served as a vital link in the nation's transportation network, carrying countless travelers between San Francisco and Atlantic City along the historic Lincoln Highway. By the early 1990s, the bridge had endured decades of heavy use and harsh weather conditions, leading to significant deterioration. Faced with the prospect of demolition, the Donner Summit community rallied to save their beloved landmark. Through tireless fundraising, letter-writing campaigns, and advocacy efforts, they secured a grant from the state of California to restore the bridge to its former glory. The restoration project, completed in 1993, meticulously preserved the bridge's original character while incorporating modern engineering techniques to ensure its long-term stability. The new concrete was carefully matched to the color and style of the original, and a parking area was added to allow visitors to safely admire the bridge and its stunning surroundings. Today, the Donner Summit Bridge stands as a symbol of community pride and a reminder of the region's rich history. Visitors can park near the bridge and walk across it, taking in panoramic views of Donner Lake, the town of Truckee, and the rugged peaks of the Sierra Nevada.
