The President George Bush Turnpike (PGBT) is a 52-mile (84 km)[4] controlled-access toll road running through the northern, northeastern and western suburbs, forming a partial beltway around Dallas, Texas, United States.

At its west end near Belt Line Road in Irving, State Highway 161 (SH 161) continues southwest to 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 (SH 190) designation.

Originally the President George Bush Turnpike was equipped with traditional toll plazas for cash payment as well as RFID-based TollTag express lanes.

However, on July 1, 2009, the cash plazas were closed and replaced with "ZipCash", an OCR-based camera system which reads the license plate and bills the owner by mail.

The loop would begin at Interstate 20 just east of the Tarrant County line and head north (along a corridor still planned as an extension of SH 161).

It would rejoin the present Turnpike alignment and head southeast to Interstate 30 west of Lake Ray Hubbard.

The short Spur 484, designated in 1970, would run from Loop 9 at Belt Line Road northeast along the present Turnpike alignment to I-635.

A stack interchange was constructed in 1990 at U.S. Highway 75 in Richardson, which quickly became a white elephant as the structure remained abandoned for several years.

In 1995 following a revision in federal laws, authorities agreed to shift to a toll financing scheme, providing an infusion of cash and new construction.

[citation needed] In late December 2015, the President George Bush Turnpike and the I-30 interchange was directly hit by a large, EF4 tornado with winds of up to 180 mph while at peak strength at around 6:52pm CDT.

[citation needed] Since the initial construction began in 1988, the turnpike was completed in a number of phases, as described here: Segment I (North Dallas).

Unstable clay soil was a significant problem in this segment, requiring contractors to use concentrated liquid stabilizers and geosynthetic reinforcement.

[citation needed] A part of President George Bush Turnpike was extended from SH 183 to Conflans Road in 2006.

The next PGBT segment, the East Branch extension, is planned to begin at the PGBT Lake Ray Hubbard Interchange at I-30, extending south-southeast to near Duck Creek Way, then southward near Mesquite Metro Airport, terminating at I-20 near Rory Galloway Day Camp.

In the longer term, the North Central Texas Council of Governments is studying a very broad outer loop around the entire Dallas–Fort Worth metroplex.
