Green River, Wyoming

History

The townsite of Green River, Dakota Territory was platted by the Union Pacific Railroad in 1867. Although the Territory of Wyoming was created on July 25, 1868, the Town of Green River was incorporated on August 21,1868 under the laws of the previous Territory of Dakota since the laws of the Wyoming Territory had yet to be written. The Town of Green River was re-incorporated on June 10, 1891 under the laws of the State of Wyoming to remove any ambiguity.

The Union Pacific Railroad reached Green River on October 1, 1868, and was supposed to be the site of a division point for the railroad. Railroad officials were surprised to find that a town of 2000 residents and permanent adobe buildings had been established there, likely requiring costly negotiations for railroad land. They moved the division point 12 mi west, creating the town of Bryan, on the Blacks Fork of the Green River. Just when Green River was on the verge of becoming a ghost town, Blacks Fork dried up during a drought and the railroad was forced to move the division point back to Green River to ensure adequate water for its steam locomotives. Bryan became the ghost town.

On May 24, 1869, John Wesley Powell launched the Powell Geographic Expedition from Green River.

On November 16, 1931, the Town of Green River passed the Green River ordinance that prohibited door-to-door selling. Other towns across the country would adopt the ordinance.

Economy

The Green River Basin contains the world's largest known deposit of trona ore. Soda ash mining from trona veins 900 and 1600 ft deep is a major industrial activity in the area, employing over 2000 persons at five mines. The mining operation is less expensive for production of soda ash in the United States than the synthetic Solvay process, which predominates in the rest of the world. The trona in Sweetwater County was created by an ancient body of water known as Lake Gosiute. Over time, the lake shrank. With the loss of outflows, highly alkaline water (salt brine) began to evaporate, depositing the beds of trona.

The four mines are run by these companies:

• Tata Chemicals Ltd.
• Genesis Alkali LLC
• Ciner Resources LP
• Solvay Chemicals Inc.

The Green River Basin also has large oil shale and natural gas reserves, which remain virtually untouched due to the high cost of extracting the oil from the hard shale formations. However, an increase in oil prices in 2008 and a national desire to become more energy independent led to an increase in well drilling and oil exploration. Expansion growth from Halliburton and Exxon, as well as other oil companies, created a mini-boom for Green River and its sister city, Rock Springs.

The 80MW Sweetwater Solar project near Green River is "the first utility-scale solar farm" in Wyoming. It was slated to come online in 2019. Concerns have been raised about its impact on antelope migration.

The city council was criticized in 2007 for its handling of a smoking ban, which caused several residents to question the council's motives.

The Mayor of Green River is Pete Rust, who was elected in November 2014.

Infrastructure

Transportation

Green River lies along Interstate 80 (I-80), a major transcontinental freeway that crosses southern Wyoming. It was designated in 1956 and constructed in phases to replace U.S. Route 30, the previous transcontinental highway on the corridor. The section around Green River was opened on October 28, 1966, and included the construction of the Green River Tunnel, a pair of tunnels that ran 1,135 ft. The tunnels closed on February 14, 2025, after a mass collision involving 26 vehicles started a fire that killed 3 people. Other highways in the city include Highway 530, which connects to Flaming Gorge, and Interstate 80 Business, which uses the old route of U.S. Route 30 through Green River.

The city government owns a Greater Green River Intergalactic Spaceport, a public use airstrip 5 mi south of the town on Highway 530. It was originally named Green River 48U for its Federal Aviation Administration identifier until 1994, when the city council passed a resolution to designate the airport as a spaceport. The same resolution included language with an "offer of sanctuary" to residents of Jupiter due to the impending collision of Comet Shoemaker–Levy 9. The airport has a 5,000 ft runway and a commemorative sign that has been replaced several times due to theft.
