Part of the Fort Worth beltway, Interstate 820 (Jim Wright Freeway) wraps around the west, north, and east sides of the city. The southern portion of the beltway is a part of IH 20. U.S. 287 combines with IH 820 along the southeast quadrant of the beltway. SH 121 and 183 overlap with IH 820 between Richland Hills and Hurst to the northeast. Tolled Express Lanes accompany the leg of IH 820 between IH 35W and SH 121 as well.
IH 820 around Fort Worth was initially planned as a complete beltway, as IH 20 was proposed to follow the Dallas-Fort Worth Turnpike. The initial route utilized SH 183 along Southwest Boulevard north to U.S. 377. This changed in 1962.1
IH 20 was eventually rerouted to a new alignment across south Fort Worth, Arlington, Grand Prairie and south Dallas. This included an overlap with IH 820. When IH 30 was relocated to the Turnpike in 1978, IH 820 was truncated to cover three of the four sides of the beltway.2
