Allegheny County, Pennsylvania
Allegheny County () is a county in the Commonwealth of Pennsylvania. It is located in Southwestern Pennsylvania. As of the 2020 census, the population was 1,250,578, making it the state's second-most populous county, following Philadelphia County. The county seat is Pittsburgh. Allegheny County is included in the Pittsburgh, PA Metropolitan Statistical Area, and in the Pittsburgh Designated Market Area. Allegheny was the first county in Pennsylvania to be given a Native American name. It was named after the Lenape word for the Allegheny River. The meaning of "Allegheny" is uncertain. It is usually said to mean "fine river". Stewart says that the name may come from a Lenape account of an ancient mythical tribe called ''"Allegewi"'', who lived along the river before being taken over by the Lenape.

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ...

Armstrong Tunnel
The Armstrong Tunnel in Pittsburgh, Pennsylvania, connects Second Avenue at the South Tenth Street Bridge, under the Bluff where Duquesne University is located, to Forbes Avenue between Boyd Street and Chatham Square. Construction The tunnel was constructed between 1926 and 1927. The chief engineer was Vernon R. Covell of the Allegheny County Public Works Department. The tunnel portals were designed by a city architect, Stanley L. Roush, who is also noted for the Smithfield Street Bridge portals, the Pittsburgh City-County Building, the Corliss Tunnel, and many other municipal projects. Characteristics The tunnel itself is characterized by twin bores of horseshoe cross-section, and bends halfway through. It also has a pedestrian walkway on the western side. Pghbridges.com reports that since the air draft flows toward the river, bicyclists are able to travel through the tunnel in that direction "with little or no effort." A legend mentioned by the site involves a notion that t ...

Rachel Carson Bridge
__NOTOC__ Rachel Carson Bridge, also known as the Ninth Street Bridge, spans the Allegheny River in Downtown Pittsburgh, Pennsylvania in the United States. The total length is including the main span and two side spans, or including the approaches. The total width of the deck is , including the roadway plus two sidewalks outside the compressive plate girder. Whereas the roadway formerly carried two vehicle lanes and two streetcar tracks, it was changed to carry four wide vehicle lanes. The 2019-2020 refurbishment reduced the lanes to three. Named for the naturalist and author Rachel Carson, a Pittsburgh native, it is one of three parallel bridges called the Three Sisters, the others being the Roberto Clemente Bridge and the Andy Warhol Bridge. The Three Sisters are self-anchored suspension bridges and are significant because they are the only trio of nearly identical bridges—as well as the first self-anchored suspension spans—built in the United States.
