County (United States) Subdivision used by most states in the United States of America

In the United States, an administrative or political subdivision of a state is a county, which is a region having specific boundaries and usually some level of governmental authority. The term "county" is used in 48 U.S. states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs respectively.

U.S. state constituent political entity of the United States

In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.

President George Bush Turnpike toll road that runs around Dallas, Texas, USA

The President George Bush Turnpike (PGBT) is a 52-mile (84 km) toll road running through the northern, northeastern and western suburbs, forming a partial loop around Dallas, Texas, United States. It is named for the late George H. W. Bush, the 41st President of the United States. At its west end near Belt Line Road in Irving, State Highway 161 continues southwest to Interstate 20 (I-20) in Grand Prairie. The discontinuous free frontage roads along the turnpike from I-35E in Carrollton east to its end at I-30 in Garland are assigned the State Highway 190 designation. SH 190 signage appears only along the Garland, Richardson, Plano, and Carrollton sections of the frontage road with the undersign "frontage road only". At intersections with city streets, only the Bush Turnpike signs are displayed, not the SH 190 signage. Prior to the construction of the main lanes as a tollway, SH 190 was used as the name of the planned main lanes too. Similarly, the part west of I-35E was planned as part of SH 161. Bush Turnpike is signed as a north–south road from I-20 to I-35E, an east–west road from I-35E to the Merritt Main Lane Gantry and as a north–south road from the Merritt Main Lane Gantry to I-30, as Bush Turnpike makes a nearly 90-degree curve in both places.
