The Household No. 1 Site is an archaeological site in Westmoreland County, Pennsylvania, United States. Located off Timms Lane in Rostraver Township, the site lies on a bluff above the Youghiogheny River.: 1, 2 Local archaeologists knew of the site in the early part of the twentieth century; the best records of the site are from amateur George Fisher, who studied the area from 1900 to 1950. More complete records were obtained after a 1980 investigation, which was part of the planning for the construction of baseball fields in the vicinity. Because archaeologists discovered a significant range of artifacts in the location, the fields were moved to allow for continued excavation. This investigation determined that the site was that of a Monongahela village.: 2 Evidence of warfare dominated the findings from the Household 1 Site. Many burials were present at the site — including sixteen at the site of one house alone — and projectile points composed a much larger percentage of the total findings than did domestic tools. Furthermore, the small total number of artifacts overall shows that the site was only occupied for a short period of time, and its location on a river bluff suggests that its site was chosen for defensibility. These discoveries, like those at many other Monongahela village sites, demonstrate that the Household residents lived in a highly martial culture.: 4 In 1986, the Household Site was added to the National Register of Historic Places for its archaeological significance.

The Smithton High-Level Bridge is a structure that crosses the Youghiogheny River between South Huntingdon Township and Rostraver Township. The bridge was opened in 1956 as one of the last links in the replacement of the old alignment of Pennsylvania Route 71 with a new four-lane freeway between Washington and the Pennsylvania Turnpike. During the same year of the bridge's completion, it was announced that the highway would become part of Interstate 70; it took on this designation in 1964 after the completion of freeway stretches in neighboring West Virginia linked PA 71 to a similar freeway in Ohio. Part of a busy truck route, the bridge is part of a highway that has been plagued by surface problems. In 1989, a crack in the superstructure, the result of a 35-year-old construction error, forced the closure of the bridge for five days, stranding truckers. The bridge was rehabilitated in 2000.

The West Newton Bridge is a structure that crosses the Youghiogheny River between the eastern and western portions of West Newton, Pennsylvania. Constructed in 1907, the bridge carries two lanes of Pennsylvania Route 136. In an era in which many truss bridges were replaced, the structure was instead rehabilitated in 1984, as part of a proposal for a historic district along West Newton's Main Street. The Youghiogheny River Trail features a parking facility adjacent to the bridge's western approach. During the summer of 2010, the bridge was temporarily closed for two weeks. Emergency repairs were needed to repair corrosion that was discovered during a routine painting project.

The Smithton Low-Level Bridge is a structure that carries Pennsylvania Route 981 across the Youghiogheny River between South Huntingdon Township and Rostraver Township, just south of Smithton, Pennsylvania. The previous structure on this site was a cantilever bridge built in 1900 to connect Smithton, which was then thriving due to its brewery, with residences on the west bank of the river; a state court ruled in favor of petitioners who demanded the creation of a bridge, but ordered that they contribute $1,200 in construction costs. Until the completion of the Smithton High-Level Bridge in 1956 (which eventually became part of busy Interstate 70), this structure was one of the most important vehicular crossings of the river. In 1986, the original bridge was replaced by a modern girder bridge.
