caption_attribution_description: English: A stack interchange between President George Bush Turnpike (top level) and U.S. Highway 75 (lower level), on the border between Richardson and Plano in Texas, February 2020. Bush Turnpike runs in this photo from west (top) to east (bottom right); U.S. 75 runs from south (left) to north (middle right).
context_page_description: The President George Bush Turnpike is a 52-mile 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 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 Rowlett, 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.
context_section_description: Since the initial construction began in 1988, the turnpike was completed in a number of phases, as described here:
  Segment I (North Dallas).  Extends from Campbell Road to Midway Road, and includes the Dallas North Tollway and U.S. Highway 75 (Central Expressway) interchanges. Opened in December 1998 (Midway Road to Preston Road) and December 1999 (Preston Road to Campbell Road).
  Segment II (Garland/Richardson). Extends from Campbell Road to State Highway 78. Opened in 2000.
  Segment III (Carrollton). Extends from Midway Road in north Dallas to Interstate 35E. Opened July 2001.
  Segment IV ("PGBT Superconnector"). Connects I-35E to the I-635 airport extension. It covers 5.2 miles (8.4 km) and was built at the cost of $339 million. Much of the expense is because the segment is built within the Trinity River wetland and comprises many miles of bridges. Construction began in January 2003 and was completed in October 2005.
  Segment V (Irving). A 3.9-mile (6.3 km) segment connecting the I-635 airport extension to the SH 161 freeway near Belt Line Road. It opened in December 2001. Unstable clay soil was a significant problem in this segment, requiring contractors to use concentrated liquid stabilizers and geosynthetic reinforcement. A part of President George Bush Turnpike was extended from SH 183 to Conflans Road in 2006.
  Segment VI ("Western Extension", Irving/Grand Prairie). A 11.5-mile (18.5 km) extension south from SH-183 in Irving to I-30 in Grand Prairie.  A portion of the Western Extension, from SH-183 to I-30 in Grand Prairie, opened in August 2009.  The remaining 6.5-mile (10.5 km) of the Western Extension, from I-30 to I-20 in Grand Prairie, opened in October 2012.
  Segment VII ("Eastern Extension", Garland/Sachse/Rowlett). A 9.9-mile (15.9 km) extension from SH-78 in Garland, through Rowlett and Sachse, and back into Garland at I-30.  The project, with a price tag of $1.04 billion, included construction of a 1-mile bridge at Lake Ray Hubbard.  Construction began in October 2008, and the Eastern Extension opened to traffic on December 21, 2011.
  Segment VIII ("East Branch", Garland/Mesquite). A proposed extension from I-30 in Garland to I-20 in Mesquite, with an estimated cost of $730 million.  In December 2015 an Environmental Impact Statement for the East Branch had been prepared but the review process was restarted in 2017. Construction is not expected until 2026.
