Mill Avenue Bridges

The Mill Avenue Bridges in Tempe, Arizona, are not just functional structures; they are historical landmarks that offer a glimpse into the past while serving as vital arteries for the city today. Spanning the Salt River, these bridges connect the bustling Mill Avenue shopping district with the rest of Tempe, and they have been a part of the city’s landscape since the early 20th century.

The Historic Original Span

The original Mill Avenue Bridge, completed in 1931 and dedicated in 1933, is a testament to early 20th-century engineering. It replaced the Ash Avenue Bridge, a one-lane structure built in 1913, which was the only crossing at the time besides the Center Street Bridge in Phoenix. This new bridge was a significant improvement, providing a more reliable route over the Salt River.

For years, this bridge was the only option for crossing the river, especially after the Ash Avenue Bridge was demolished in 1991. Even though the Salt River was often dry due to upstream dams, the bridge occasionally faced the wrath of nature when heavy rains or dam releases sent water rushing through the valley. Remarkably, the bridge withstood these challenges, including a massive flood in 1980 when water surged at a staggering 200,000 cubic feet per second. Its resilience earned it a spot on the National Register of Historic Places in 1981 and the Tempe Historic Property Register in 1999.

The Modern Companion

As Tempe grew, so did the need for more efficient traffic solutions. In response, the city constructed a new bridge parallel to the original one in the early 1990s. Despite setbacks from floods that delayed its completion, the new Mill Avenue Bridge opened in 1994. This addition allowed for two lanes of traffic in each direction, greatly alleviating congestion and making travel more convenient.

With the opening of the new bridge, the old unbridged crossing was permanently closed. This development marked a new era for the city, ensuring that monsoon storms and dam releases no longer caused significant disruptions.

Tempe Town Lake Transformation

In 1999, the area around the bridges underwent a dramatic transformation with the creation of Tempe Town Lake. This artificial lake revitalized the downtown area, turning the bridges from mere crossings into picturesque landmarks. The lake, flanked by mid-rise offices and recreational areas, became a hub of activity and development.

One of the highlights of the year is the CBS 5 July 4 Tempe Town Lake Festival, where fireworks are launched from the bridges, creating a dazzling display that draws visitors from all around. This annual event showcases the bridges' role as not just transportation links but also cultural and social focal points.

Rail Bridges and Modern Connections

The Mill Avenue Bridges complex also includes two rail bridges downstream. One of these has stood for decades, while the other was added to accommodate the Phoenix Light Rail system, which began operation in 2008. These rail bridges further integrate Tempe into the broader Phoenix metropolitan area, providing efficient and sustainable transport options.

In 2018, the bridges were designated as part of Historic U.S. Route 80 by the Arizona Department of Transportation, cementing their status as historical and cultural icons.

A Testament to Resilience

The bridges have not been without their challenges. In 2020, a nearby rail bridge partially collapsed due to a train derailment and fire, demonstrating the ongoing need for maintenance and care of these vital structures. Despite such incidents, the Mill Avenue Bridges continue to stand as symbols of resilience and adaptability.
