Notes:

• Yeomet was located near the present day California Route 49 crossing of the Cosumnes River by the confluence of the North Fork and Middle Fork of the Cosumnes River. Yeomet was once known as "Forks of the Cosumnes." The location coordinates provided here are only to show the approximate location of the confluence and should not be considered the exact location of the bridge. This inventory entry represents the suspension bridge for which a photograph exists in the Lawrence & Houseworth collection titled "Suspension Bridge over the Cosumnes River, At Yeomet, El Dorado County". This image exists in several online archives.
• Barry Parr, consulting Erwin Gudde's California Gold Camps (University of California Press), writes that Gudde notes the bridge is located "at Yeomet and says it was marked on the County Map in 1866, and was owned by S.E. Huse for a decade. Of Yeomet, Gudde writes: 'Amador County. At the junction of the forks of Cosumnes River, formerly in El Dorado County'. Gudde says the camp developed in 1849 or 1850 and prospered for a number of years, but says nothing further about the bridge." Barry also notes that some sources cite Yeomet as located in Calaveras County, but this is because Amador County was created in 1854 from Calaveras County. Barry continues: "The California Division of Mines Bulletin 141, Geological Guidebook along Highway 49, mentions the Highway 49 bridge across the Cosumnes as also known as the Huse Bridge."
• The October 14, 1976 edition of The Mountain Democrat Times (Placerville, California) has an article about the Huse Bridge (from the Heritage Association of El Dorado) describing Huse's Bridge:

  "E.P. Bowman, an early motel keeper in Yeomet had a ferry across the Cosumnes and by 1852 had built a bridge there (J.M. Watrous had a ferry there also). Traffic was heavy and... [the tolls were] as much a 'gold mine' as most of the nearby river claims which ran for miles above and below the town. (Yeomet falls was below the bridge). The famous Mother Lode crossed the river in the vicinity of the town. Samuel Huse bought the bridge at Yeomet in about 1862 and owned it until his death. His widow Laura sold the wire suspension bridge and the exclusive right to collect tolls to John Ballard and W.H. Martin in 1883. William Miller purchased the property in 1887."

  It is unclear if the 1852 E.P. Bowman bridge was the same structure as the suspension bridge purchased by Huse ten years later, but it has been assumed here pending additional details.
• An obituary for in the August 28, 1949 edition of the Oakland Tribune for Lilian Williams presents a stronger tie between E.P. Bowman and S.E. Huse: "With her foster parents, the E. P. Bowmans, Mrs. Williams spent her childhood in Oakland, San Francisco and Yeomet, between Plymouth and Placerville. Bowman and her foster uncle, S.E. Huse, owned a hotel at Yeomet. They also built and operated a toll bridge there on the Cosumnes River, over which most of the heavy machinery and mining equipment was transported to the old Mother Lode mines."

Notes:

• The location of this bridge was near the present day location of Cosumne in Sacramento County, just east of Sloughhouse. The location coordinates provided here are only to show the approximate location of present-day Cosumne and should not be considered the exact location of the bridge. Don Sayenga writes: "The exact location was at the intersection of [present-day] Dillard Road and State Route 16 a very short distance east of Sloughhouse, Sacramento County, California... The whole area at that time was known as Daylor's Ranch."
• Don Sayenga notes an F.W. Panhorst (of the California Highway Department) citation:

  "Alta California July 27, 1852 reprinting an article from Sacramento Union mentions a wire suspension bridge built in Sacramento County across the Cosumnes. The span is described as 150 feet with a roadway width of 12 feet. One W.D. Wilson is mentioned as owner and designer. This structure, according to our best information, was the first suspension bridge in California."

• A January 14, 1862 Sacramento Bee article notes:

  "The quartz mill and house of the brothers Wiley, just beyond Butte City, were carried away by the torrent. At Ione City, William's brick stable had fallen, and several other houses had met with a like fate. On Sutter creek, the loss and damage had been terrific - bridges and houses being carried off like chaff. Mr. Haywood, proprietor of a quartz mill on Sutter creek, had been a loser to the amount of at least $75,000. We have it from good authority that in the counties of Calaveras and Amador not a bridge is left standing. Below Ione City, it is thought that there has been loss of life."
  
  "Last Saturday night, the reports of minute guns were heard, as if signals of distress, coming from the direction of a house where lived Mr. Martin and his family. The whole of Ione Valley was many feet under water. No boats were to be had, so that assistance might be rendered those in danger and distress. In a short time a heavy crash was heard, the signals of distress ceased, and our informant tells us that when he left the general impression was that Martin and his family had lost their lives. The wire suspension bridge over the Cosumnes river had disappeared - the house known as Wilson’s Exchange has also been washed away, and Daylor’s adobe house is flat with the ground. These facts go to show that throughout the mountain districts, as well as in the valleys, the destruction of property and loss of human life exceed the worst that was anticipated, and we shall hear repetitions of such tales of distress as the avenues for communication are gradually opened to us."

  which seems to imply a relationship between the Ione Valley, the Cosumnes River, and the bridge at Wilson's Exchange, but this may have just been coincidental that both "Ione Valley" and Wilson's Exchange were mentioned in the same paragraph; they are nearby. Present-day Ione is in Amador County a few miles east of Sacramento County. The Cosumnes River forms the northern border of Amador County several miles to the north of present-day Ione. Barry Parr notes that the Cosumnes River does not flow through the "Ione Valley," but Barry writes: "Recalling Daylor’s name in Historic Spots of California: 'Daylor established himself as a trader and hotel-keeper on the Cosumnes River about a mile east of Slough House. This place, which was at first known as Daylor’s Ranch, later became the Cosumnes post office.' (p. 290) The site of Cosumnes post office is about five miles downstream from Bridge House, and both are on the Sacramento-Ione Road.

  "Mr. Wilson and part of the company concluded to seek the land of gold, while others kept to the original design of going to Oregon. On his arrival Mr. Wilson mined for a short time on Mormon Island and then moved to Hangtown, now Placerville, where in the winter of 1848-49 he built the first house erected in that place. The family then comprised six children; five more were born in California; nine grew to maturity and seven are living in 1889. In the spring of 1850 he moved down on the Cosumnes and purchased 6,000 acres of the Hartnell Grant, and built a tavern, long known as Wilson’s Exchange, across the river from what is now the Cosumnes post office. He was postmaster from the establishment of that office until 1868. He was by trade a millwright and built the first suspension bridge on the Cosumnes."

Notes:

• The location coordinates provided here are the approximate location of this bridge, crossing the Cosumnes between present day El Dorado and Amador counties at Michigan Bar (as named on USGS topographical maps) on current Latrobe Road where Clark Creek meets the Cosumnes River. Note that USGS topographical maps show another, more prominently marked, "Michigan Bar" a few miles west in Sacramento County.
• A California Highways and Public Works article (unsure of exact citation but it may be the article on the history of California bridges that appeared in the 1941 June issue and was reprinted in the 1950 September/October issue) says "there were four [suspension bridges] on the Cosumnes River, one of which (Lamb's Bridge on the Latrobe-Plymouth Road) killed one man and seven horses when it fell in 1869."
• The October 14, 1976 edition of The Mountain Democrat Times (Placerville, California) has an article about the nearby Huse Bridge (from the Heritage Association of El Dorado) which mentions Lamb's Bridge: "...Lamb's Bridge, several miles downriver, was reconstructed in 1872 and was also a wire bridge of the same type [as Huse's]."
• The Statutes of California passed at the Fourteenth Session of the Legislature, 1863 records: "Chapter XLI. An Act to grant to Larkin Lamb and his Associates the right to construct and maintain a Toll Bridge across the Cosumnes River, in the Counties of Amador and El Dorado. Approved March 6, 1863. The People of the State of California, represented in Senate and Assembly, do enact as follows: Section 1. Larkin Lamb, and those he may associate with him, their heirs and assigns, shall have full power to build, erect, construct, and maintain a public toll bridge across the Cosumnes River, at a point about eighty (80) rods below Dutch Hill;..."
• A November 12, 2017 article in Ledger Dispatch (of Amador and Calaveras counties) titled "Vestiges of Amador-Communities Along the Cosumnes, Part VI: The Lower Reaches - Michigan Bar to Wisconsin Bar" by Deborah Coleen Cook gives a more complete history of Lamb's bridge citing the enactment (February 9, 1863) of the bill to permit construction, construction completing six months later, failure of one of the cables in 1869 under the weight of a large freight wagon, and another cable/anchorage failure in 1872 while the bridge was undergoing major repairs.
