Interstate 30 (I-30) is a major Interstate Highway in the southern states of Texas and Arkansas in the United States. I-30 travels 366.76 miles (590.24 km) from I-20 west of Fort Worth, Texas, northeast via Dallas, and Texarkana, Texas, to I-40 in North Little Rock, Arkansas. The highway parallels U.S. Route 67 (US 67) except for the portion west of Downtown Dallas (which was once part of I-20). Between the termini, I-30 has interchanges with I-35W, I-35E, and I-45. I-30 is known as the Tom Landry Freeway between I-35W and I-35E, within the core of the Dallas–Fort Worth metroplex.

👉 Interstate 30 in Texas in the context of Interstate 45 (Texas)
Interstate 45 (I-45) is a major Interstate Highway located entirely within the U.S. state of Texas. While most primary Interstate routes which have numbers ending in "5" are cross-country north–south routes, I-45 is comparatively short, with the entire route located within Texas. Additionally, it has the shortest length of all the primary Interstates divisible by 5, and is the only Interstate Highway of such. It connects the cities of Dallas and Houston, continuing southeast from Houston to Galveston over the Galveston Causeway to the Gulf of Mexico.
I-45 replaced U.S. Highway 75 (US 75) over its entire length, although portions of US 75 remained parallel to I-45 until its elimination south of Downtown Dallas in 1987. At the south end of I-45, State Highway 87 (SH 87, formerly part of US 75) continues into downtown Galveston. The north end is at I-30 in Downtown Dallas, where US 75 used the Good-Latimer Expressway. A short continuation, known by traffic reporters as the I-45 overhead, signed as part of US 75 and also part of unsigned I-345, continues north to the merge with the current end of US 75. Traffic can use Spur 366 (better known locally as the Woodall Rodgers Freeway) to connect to I-35E at the north end of I-345.

Interstate 30 in Texas in the context of Interstate 345 (Texas)
Interstate 345 (I-345) is an unsigned 1.4-mile-long (2.3 km) Auxiliary Interstate Highway in the city of Dallas within the US state of Texas. It is a freeway that connects I-45 (which ends at the interchange with I-30) with U.S. Highway 75 (US 75; North Central Expressway) at State Highway Spur 366 (Spur 366; Woodall Rodgers Freeway). Few maps actually display the road as I-345; signposts on the road show US 75 northbound, while southbound the highway is signed as I-45. In recent years, a debate over whether to maintain or decommission I-345 has received increased attention from several Dallas media outlets. TxDOT elected to maintain the freeway by lowering it below ground and removing frontage roads.
Interstate 30 in Texas in the context of Margaret McDermott Bridge
The Margaret McDermott Bridge is a conventional concrete pier-and-beam freeway bridge with cable-stayed bike lines over the Trinity River in Dallas, Texas. It replaced the late-1950s to early-1960s Interstate 30 (I-30) bridge, which reached its end of life. It was partially designed by Santiago Calatrava, and is part of the Trinity River Project and the Horseshoe Project. It was named for Margaret McDermott, an area philanthropist.
