The Thomas Guide

Before digital maps became commonplace, how did we navigate the complex roads that connect us?

For many motorists, it was paper road maps or atlases. One of the most popular ones in California was the Thomas Guide.

Founded in Oakland by three brothers, the Thomas Guide is a series of folding maps and spiralbound atlases that featured detailed maps of the largest metropolitan areas in the United States.  In Southern California, these atlases were almost ubiquitous in people’s backseats and glove compartments. Businesses would even use the Thomas Guide map grids for their location in advertisements.  

Route 66

Established in 1926, Route 66 connected the Great Lakes to the Pacific Ocean. In California, Route 66 crossed the Mojave Desert, passed through the Cajon Pass, and ended in Santa Monica. Known as the “Mother Road” and “Main Street of America,” the highway traced the paths first tread by indigenous groups and later reinforced by waves of settlers who came by wagon, then by train, and finally by automobile. They travelled for many reasons: depression-era farmers in search of a better life, soldiers serving their country, free spirits looking for adventure.

Much of the original Route 66 was replaced by interstate highways eventually leading to its removal from the U.S. Highway System in 1985. Still, at 100 years old, its legacy lives throughout the County as portions of the Mother Road in San Bernardino County remain drivable today as the National Trails Highway, State Route 66, and Foothill Boulevard.
