Clark Avenue Railroad Underpass

a.k.a. Bonanza Road Underpass

Jct. of Bonanza Rd. and Union Pacific Railroad Tracks, Las Vegas, NV
The underpass represents the symbolic "opening up" of the Westside, now called West Las Vegas, after 31 years of being physically separated from the east side of Las Vegas by the Union Pacific railroad tracks. Since 1905, when the Westside was settled, then called the McWilliams Townsite, relations between the two communities had been hindered by dangerous crossings over the railroad tracks, delaying water and sewer services, electric lighting, and commercial trade. The Westside was also slowly becoming more and more segregated, as residents of thriving black Las Vegas neighborhoods were forced to relocate their homes and businesses to the Westside. Overcrowding resulted in the construction of substandard housing, exacerbating the already noxious conditions created by the lack of clean running water. The construction of the underpass was a civic attempt to ease the straining relationship between the white and black communities, as well as a means to facilitate infrastructure improvement on the Westside.

Furthermore, the construction of the underpass was made possible through federal funding under the Works Progress Administration (WPA), a program under the "New Deal" introduced by President Roosevelt in 1935 to bring relief to the millions of people left without jobs after the Great Depression. The Clark Avenue Underpass was one of 78,000 bridges constructed under this program. The spirit of the New Deal program and WPA befitted the construction of the underpass and what it stood for, and although the underpass, directly and indirectly, improved the quality of life for many Westside residents, it did not stimulate economic redevelopment of the Westside as it had hoped to.

The underpass structure retains the integrity of location, setting, feeling, and association. The structure has not been moved, and the surrounding neighborhood has changed little, with the exception of additional industrial development. The structure continues to serve the community as a convenient way to traverse the railroad tracks and is heavily used as one of very few of these structures in the city. The simple design details and elegant structural aesthetic belies not only the use of the structure, but its status as a federally funded project, continuing to associate it with the time in which it was built-when trains were moving supplies and workmen, and highways were the post-Depression American's ticket to freedom and relief from drudgery.

Although not as strong as the other qualities, the underpass retains the integrity of materials, workmanship, and design. The underpass has been widened, however, the additions were thoughtfully executed, continuing the original design elements, materials and dimensions. It should be noted that the structure is not being submitted for nomination based on its retention of these qualities, so much as its significant social importance and association with significant national and local events.

The period of significance has been defined as 1936, the year of construction, to 1954, the 50year mark.

Nevada was once part of Mexico: Before it became part of the United States, Nevada was part of Mexico's Alta California territory. In fact, the state's name comes from the Spanish word for "snow-covered," a reference to the Sierra Nevada mountain range.
Clark County, Nevada is located in the southernmost part of the state and has a rich and fascinating history. The area that is now Clark County was first inhabited by Native American tribes, including the Paiute people, who established settlements along the Colorado River.

In the mid-19th century, Mormon pioneers settled in the Las Vegas Valley, establishing a fort and bringing irrigation techniques that transformed the desert landscape. However, their presence was short-lived, and by the 1880s, the area was mostly abandoned once mining activity diminished.

The history of Clark County took a significant turn in 1905 when the railroad arrived in the area, linking it with the rest of the country. This development led to the establishment of Las Vegas as a bustling railroad town, attracting people from various backgrounds and sparking rapid growth in the region.

The next major milestone in Clark County's history came in 1931 when the state of Nevada legalized gambling. This decision forever altered the county's landscape, as casinos and entertainment venues began to flourish. The construction of the Hoover Dam, also in the 1930s, provided employment opportunities and further boosted the economy of Clark County.

Over the following decades, Clark County continued to see exponential growth, driven largely by the tourism and entertainment industries. Las Vegas, in particular, became known as the Entertainment Capital of the World, with its world-class resorts, casinos, and vibrant nightlife attracting millions of visitors annually. Today, Clark County remains a major tourism destination and a dynamic hub of culture, entertainment, and economic activity in the southwestern United States.
