US 99: The Historic Pacific Highway

Hey there, fellow road trip enthusiasts! Ever heard of US 99? This legendary highway, once the main north-south route along the West Coast, has a fascinating story to tell. Let's dive into the history of US 99, explore its original path, and discover what happened to it after Interstate 5 came along. Buckle up, because this is going to be an exciting journey!

What Was US 99?

US 99 was more than just a road; it was a vital artery connecting the states of Washington, Oregon, and California. Officially established in 1926, it served as the primary north-south highway on the West Coast for decades. Think of it as the original I-5! This iconic route played a significant role in the development of the West Coast, facilitating trade, tourism, and connecting communities long before the Interstate system existed. Imagine the bustling towns and roadside attractions that flourished along this route, each with its own unique charm and stories to tell. From the majestic redwood forests of California to the lush landscapes of Oregon and the scenic beauty of Washington, US 99 offered a diverse and captivating travel experience.

The History of US 99: A Road Through Time

The story of US 99 actually starts way before 1926. The groundwork for this highway was laid by its predecessor, the Pacific Highway, which was an auto trail dating back to the early 1910s. The Pacific Highway was conceived as a way to connect the Pacific Coast states, and its construction marked a significant step forward in transportation infrastructure. Over time, as automobile travel became more popular, the need for a more formalized and well-maintained route became apparent. This led to the establishment of the numbered US highway system, and in 1926, the Pacific Highway was officially designated as US 99. This new designation brought with it improved standards for road construction and maintenance, further solidifying US 99's role as a crucial transportation corridor.

Key Milestones in US 99's History

• Early 1910s: The Pacific Highway auto trail is established.
• 1926: The Pacific Highway is officially designated as US 99.
• Mid-20th Century: US 99 reaches its peak as the premier West Coast highway.
• 1950s - 1970s: Interstate 5 is constructed, gradually replacing US 99.
• 1968: US 99 is officially decommissioned, but many sections remain as local roads.

US 99's Routing: A West Coast Journey

US 99 stretched from the Canadian border in Washington all the way down to the Los Angeles area in California. Let's take a closer look at its routing through each state:

US 99 in Washington

In Washington, US 99 was the main north-south thoroughfare, connecting major cities like Seattle, Tacoma, and Everett. The highway entered the state from Canada and ran through the heart of Western Washington. Think of the bustling cityscapes gradually giving way to the scenic beauty of the Pacific Northwest. Travelers along this stretch would have experienced a diverse range of landscapes, from urban centers to picturesque small towns and rolling hills.

US 99 in Oregon

As US 99 entered Oregon, it continued its southward journey, linking cities such as Portland, Salem, and Eugene. Oregon's portion of US 99 was particularly scenic, winding through the lush Willamette Valley and offering breathtaking views of the Cascade Mountains. Imagine driving through verdant landscapes, with the majestic peaks of the Cascades looming in the distance. The highway provided access to numerous charming towns and natural attractions, making it a favorite among travelers seeking both convenience and beauty.

US 99 in California

California was the longest stretch of US 99, traversing much of the state's length. It connected major population centers like Sacramento, Fresno, and Bakersfield, eventually reaching the Los Angeles area. This section of US 99 was crucial for agriculture and commerce, serving as a vital link between the state's fertile farmlands and its bustling urban markets. The landscape varied dramatically along this route, from the agricultural heartland of the Central Valley to the urban sprawl of Southern California.

The Rise of Interstate 5 and the Decline of US 99

So, what happened to this legendary highway? The answer lies in the rise of the Interstate Highway System. In the 1950s and 60s, the US government embarked on an ambitious project to build a network of high-speed, limited-access highways across the country. This new system, designed for efficient long-distance travel, would eventually lead to the decline of many older highways, including US 99.

Interstate 5 (I-5) was constructed as the primary replacement for US 99. Built to modern standards, I-5 offered a faster and more direct route, bypassing many of the towns and cities that US 99 had served. As I-5 opened in sections, traffic gradually shifted away from US 99. Businesses that had once thrived along the older highway began to suffer, and the economic landscape of many communities changed dramatically.

By 1968, US 99 was officially decommissioned. However, this doesn't mean the road disappeared entirely. In many areas, sections of the old highway were retained as local roads, often bearing names like
