Bonneville Speedway (also known as the Bonneville Salt Flats Race Track) is an area of the Bonneville Salt Flats northeast of Wendover, Utah, that is marked out for motor sports. It is particularly noted as the venue for numerous land speed records. The Bonneville Salt Flats Race Track is listed on the National Register of Historic Places. [1]

Contents

The salt flats were first used for motor sports in 1912, but did not become truly popular until the 1930s when Ab Jenkins and Sir Malcolm Campbell competed to set land speed records.

A reduction of available racing surface and salt thickness has led to the cancellation of events at Bonneville, such as Speed Week in 2014 and 2015. [2] Available racing surface is much reduced with just 2.5 miles (4.0 km) available [2] instead of the 9-mile (14 km) courses traditionally used for Speed Week. [3]

Track layouts

Salduro is a ghost town located on the south boundary of Bonneville Speedway, next to the Western Pacific Railroad. Salt Lake City newspapers ran an advertisement in 1914 for a special train to Salduro where the "fastest machines in the world will compete for the world's record on the famous salt beds, which afford the finest races in America. No dust." Salt Lake City mayor Samuel C. Park and Utah Governor William Spry attended. A rest area on Interstate 80 was built on the former settlement, and a plaque there commemorates the land speed records. 2014-07-05 13 00 15 Sign describing the Bonneville Salt Flats at the Bonneville Salt Flats Rest Area on Interstate 80 near the Bonneville Salt Flats, Utah.JPG
Salduro is a ghost town located on the south boundary of Bonneville Speedway, next to the Western Pacific Railroad. Salt Lake City newspapers ran an advertisement in 1914 for a special train to Salduro where the "fastest machines in the world will compete for the world's record on the famous salt beds, which afford the finest races in America. No dust." Salt Lake City mayor Samuel C. Park and Utah Governor William Spry attended. A rest area on Interstate 80 was built on the former settlement, and a plaque there commemorates the land speed records.

Historically, the speedway was marked out by the Utah Department of Transportation at the start of each summer. Originally, two tracks were prepared; a 10-mile (16 km) long straightaway for speed trials and an oval or circular track for distance runs, which was typically between 10 and 12 miles (16 and 19 km) long depending on the condition of the salt surface.

Since at least the 1990s, track preparations have been the responsibility of the event organizers. Days or weeks in advance, the track preparers identify an area best suited for their track layouts and begin grading the tracks. Surveyors are brought in to survey the timing trap distances. A day before racing begins, the track markers are added.

Originally, the straightaway was marked with a broad black line down its center. This was eventually changed to lines down either side, as the center line wore out too quickly. As the costs for painting the lines has gone up, organizations have switched to flags and cones as track markers. The last event to use black lines was Speed Week, August 2009. [5]

The number of tracks and the timed sections for each track are set according to what is most beneficial for each event. Large public meets such as Speed Week run as many as four tracks with several timed miles, usually starting with the second mile and running to the fifth mile. Smaller meets that typically only run world record attempts will utilize a single track, with one timed mile and one timed kilometer in the middle of the track. Additional marks and cones indicate the end of the track and the position of timing equipment.

Deteriorating track conditions

The annual Speed Week was cancelled in both 2014 and 2015, as were many land-speed racing events, due to deteriorating track conditions. [2] [3] Heavy rains caused a layer of mud from surrounding mountains to flow onto the flats, covering approximately 6 mi (9.7 km) of the track. Although another section of the flats would normally be used, nearby salt mining operations had reduced the size of the alternative track. [3]

The depth of the salt crust at Bonneville has also been decreasing, possibly leaching into a saltwater aquifer. Measured at as much at 3 ft (0.91 m) in the 1940s and 50s, it has been reduced to just 2 in (0.051 m) in 2015.

Though recent studies have been made (since 1960), the causes of this deterioration are not clear, although the evidence points toward both local climatic changes and salt mining. Some strategies were devised to revert the decreasing salt surface, such as pumping back salt, though this had no effect. [3]

Events and meetings

In August, the Southern California Timing Association [6] and Bonneville Nationals Inc. [7] organize Speed Week, the largest meet of the year, which attracts several hundred drivers who compete to set highest speed in a range of categories. Bonneville Speed Week has been taking place since 1949. [8]

In late August, the Bonneville Motorcycle Speed Trials are held. [9]

USFRA Test-n-Tune event in 2024

In September each year is the World of Speed, (similar to Speed Week) organized by the Utah Salt Flats Racing Association (USFRA). The USFRA also hosts a "Test-n-Tune" event in the summer prior to the World of Speed. [10]

In October, the Southern California Timing Association puts on World Finals, a scaled-down version of Speed Week. This event tends to have cooler weather and often drier salt than Speed Week does. There are less spectators and it tends to draw serious racers, as this event is the last chance to break a land speed record and be in the SCTA record book for that year.

Each year, there are usually a few private meets that are not publicized scattered among the larger public meets.

Land speed records

Numerous land speed records in various vehicle categories and classes have been set on the Bonneville speed way. In 1960, Mickey Thompson became the first American to break the 400 miles per hour (640 km/h) barrier, hitting 406.60 miles per hour (654.36 km/h) and surpassing John Cobb's 1947 one-way Land speed record of 403 miles per hour (649 km/h). Other notable examples of Bonneville speed records include:

Several motor-paced racing speed records have been attempted at Bonneville.

In 1985, American cyclist John Howard set a then world record of 244 km/h (152 mph).

On 15 October 1995, Dutch cyclist Fred Rompelberg achieved 268.831 km/h (167.044 mph), using a special bicycle behind a dragster with a large shield. [14]

In 2016, Denise Mueller-Korenek claimed a women's bicycle land speed record at 147 mph (237 km/h). She was coached by Howard. It is not clear which authority was supervising the record attempt. [15]

In 2018, Mueller-Korenek broke her own women's record and the men's record at a speed of 183.9 miles per hour (296.0 km/h). [16]

<span class="mw-page-title-main">Motorcycle land-speed record</span>

The motorcycle land-speed record is the fastest speed achieved by a motorcycle on land. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions. AMA National Land Speed Records requires two passes the same calendar day in opposite directions over a timed mile/kilometre while FIM Land Speed World Records require two passes in opposite directions to be over a timed mile/kilometre completed within two hours. These are special or modified motorcycles, distinct from the fastest production motorcycles. The first official FIM record was set in 1920, when Gene Walker rode an Indian on Daytona Beach at 104.12 mph (167.56 km/h). Since late 2010, the Ack Attack team has held the motorcycle land speed record at 376.36 mph (605.69 km/h).

Theodore Herbert Tetzlaff was an American racing driver active in the formative years of auto racing. He competed in the first four Indianapolis 500s, with a highest finish of second in 1912. He earned the nickname "Terrible Teddy" due to his rough treatment of his vehicles. His wide-open throttle racing style would variously win a race, blow up his engine or cause him to crash. As auto racing strategies evolved from the early "go as fast as you can and see if you can stay on the track," Tetzlaff's success in the sport waned.
