(Sweetwater County, Wyo. - December 29, 2022)     The Sweetwater County Historical Museum often fields questions from visitors about the origins of the pedestrian viaduct and underpass in Green River. Decades ago, distinguished local historian Marna Grubb provided an excellent summary of those origins in one of her many articles. Marna was a regular contributor to “Echoes from the Bluffs,” a series of accounts about Green River and Sweetwater County history that ran in the Green River Star from 1998 to 2003. The “Echoes” articles were later incorporated into a four-volume set of books published by the Green River Historic Preservation Commission and available for purchase at the Sweetwater County Historical Museum in Green River. They can also be found at the county libraries in Rock Springs and Green River.

Marna’s “Echoes from the Bluffs” article about the viaduct and underpass is reproduced below:


Underpass and Pedestrian Viaduct

By Marna Grubb

          Today, traveling from one side of Green River to the other is accomplished with great ease in a short period of time, but this was not always the case.

          For many years, Green River was a town of three-to-four thousand people located north and south of the railroad tracks and north of the river. Getting across the railroad tracks often presented long delays, while citizens would wait for the passing of long freight trains, or the heavy passenger and freight switching accomplished in the railroad yards.

          In October of 1935, Green River's town council approved a proposal to the Union Pacific Railroad for the elimination of the railroad crossing at Elizabeth Street (North First East) with the construction of an underpass at West Second South and a pedestrian overhead crossing of the railroad tracks at the Elizabeth Street crossing.

          This proposal was reported to have been brought about by the "persistence of Green River's popular mayor and his loyal supporting town council" according to The Green River Star of August 1937. Samuel S. Hoover was mayor from 1935 to 1939.

          The underpass was opened to public use in August of 1937, and The Green River Star reported that "This improvement has been at the cost of approximately $160,000 and one must see this structure to realize its beauty and fine construction, with a pedestrian walk on one side with steel railings for protection. The entire length is lighted by artistic iron lamp posts at the top of which are attractive large globes of the latest design."

          The underpass was constructed by the Inland Construction Company of Omaha, Nebraska.

          In September of 1937, The Green River Star reported that "Police Chief Chris Jessen is making an appeal to children, and particularly to parents, to avoid possible serious accidents by discontinuing the use of the underpass as a playground. Several children were reported to have been using the runways for roller skating and wagon coasting lanes."

          In the Agreement of September 7, 1936, the railroad agreed to grant a right-of-way for a pedestrian viaduct over the railroad tracks, the State Highway Department agreed to construct the viaduct, and the town agreed to take and maintain the viaduct. If any major repairs were needed, the town would need to notify the railroad.

          In 1937, the Wyoming State Highway Department awarded the low bid of $66,931 to Inland Construction Company of Omaha, who also were the contractors on the underpass project.

          The Green River Star, in December of 1936, reported that “The pedestrian overpass will be a decided contribution to the safety of Green River residents, particularly the children who must traverse the dangerous railroad tracks four times daily in their progress to and from school. The cost of the project would be out of Federal funds appropriated for railroad crossing elimination, but would be under the supervision of the Wyoming Highway Department.”

          The pedestrian overpass was opened to the public in June of 1938, and Mayor Hoover reported that it eliminated the crossing of 21 double rails, main line and switching lines.

(Sweetwater County, Wyo. - December 16, 2022)     A new YouTube video about the long-vanished community of Bitter Creek is now available online, the Sweetwater County Historical Museum announced on Friday.

About 34 miles east of Rock Springs, Bitter Creek once was home to a railroad depot, stockyards, huge sheep shearing sheds, a school, a post office, housing for Union Pacific employees, and the Varley Mercantile, but nothing remains now but a concrete water tower base, a tall, deteriorating water softener tank, and a few foundations.

Produced by museum staff and volunteers, A History of Bitter Creek, As Told by Ed Varley, can be found on the museum’s YouTube channel at


Varley and his wife Rae Dell are long-time Point of Rocks residents. He was born in 1936, grew up in Bitter Creek, and attended school there through the 8th Grade. After that, he attended the Rock Springs High School, graduating in 1954. He is the author of two books:  Bitter Creek Kid, and Grand Pa’s Stories - A Local History. Museum Executive Director Dave Mead and Public Engagement Coordinator Aidan Brady interviewed him at his Point of Rocks home. Afterward, Varley provided them a guided tour of the Bitter Creek site.

The interview made possible a rare,  and very personal, account of life in the little hamlet from the 1930s through the 1950s. By the early to mid-1970s, Bitter Creek was in its twilight - the Post Office there was discontinued in 1971, and the Union Pacific depot was torn down in 1974. Little remains now but memories, like those of Ed Varley.

A History of Bitter Creek, As Told by Ed Varley is part of the Smithsonian Institution’s “Museum on Main Street,” project, co-hosted by the Sweetwater County Historical Museum, Wyoming Humanities / ThinkWY, and the Green River Chamber of Commerce. The museum will always be grateful to Ed and his extended family for making the video possible.

(Sweetwater County, Wyo. - November 26, 2022)     The back-and-forth story of Sweetwater County, Wyoming’s two county seats - South Pass City and Green River - is the subject of a new article on the website of the University of Wyoming’s American Heritage Center, the Sweetwater County Historical Museum in Green River said today.

Gold was discovered in the area of what would soon become South Pass City in 1866. Prospectors and others rushed in, and within a year, the little boom town’s population had swelled to 2,000. In 1867, Carter County, Dakota Territory, (named for Judge William Carter of Fort Bridger), was established, and South Pass City was designated its county seat. In 1868, Wyoming Territory was carved out of Dakota Territory. In 1869, Carter County became Sweetwater County, and South Pass City continued to be the county seat. (In those days, Sweetwater County was immense, stretching all the way from the Utah/Colorado line in the south to the Montana border in the north.)

The Heritage Center’s “The ‘Peculiar Vibrations’ of the Sweetwater County Seat” picks up the tale of the political wrangling that followed. By 1873, South Pass City’s gold was swiftly playing out, and “the county commissioners started to discuss moving the county seat seventy miles south to Green River, which was a major town on the primary transportation route through both Wyoming and the nation: the Union Pacific Main Line or the Transcontinental Railroad. In the years leading up to the move, suffice to say some drama ensued.”

In 1874, Sweetwater County’s commissioners made the county seat’s move to Green River official, (at least for the time being,) but the die-hard residents of South Pass City weren’t going to give in without a fight. Over the next two years, county records moved back and forth between the two towns no fewer than five times. By 1876 the dust had settled and Green River’s new adobe-brick courthouse (and seat of county government) was completed. Finally, the transition was finished.
