Interstate 35W (Texas) in the context of "Interstate 30 in Texas"

Interstate 35E (I-35E), a north–south Interstate Highway, is the eastern half of I-35, where it splits to serve the Dallas–Fort Worth metropolitan area. I-35 splits into two branch routes, I-35W and I-35E, at Hillsboro. I-35E travels north for 97 miles (156 km), maintaining I-35's sequence of exit numbers. It travels through Dallas before rejoining with I-35W to reform I-35 in Denton.

During the early years of the Interstate Highway System, branching Interstates with directional suffixes, such as N, S, E, and W, were common nationwide. On every other Interstate nationwide, these directional suffixes have been phased out by redesignating the suffixed route numbers with a loop or spur route number designation (such as I-270 in Maryland, which was once I-70S) or, in some cases, were assigned a different route number (such as I-76, which was once I-80S). In the case of I-35 in the Dallas–Fort Worth area, since neither branch is clearly the main route and both branches return to a unified Interstate beyond the cities of Dallas and Fort Worth, the American Association of State Highway and Transportation Officials has allowed the suffixes of E and W in Texas to remain to the present day. I-35 also splits into I-35E and I-35W in Minneapolis–St. Paul, Minnesota, for similar reasons as the I-35 split in the Dallas–Fort Worth area.

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.

The term Cross Timbers, also known as Ecoregion 29, Central Oklahoma/Texas Plains, is used to describe a strip of land in the United States that runs from southeastern Kansas across Central Oklahoma to Central Texas. Made up of a mix of prairie, savanna, and woodland, it forms part of the boundary between the more heavily forested eastern country and the almost treeless Great Plains, and also marks the western habitat limit of many mammals and insects.

No major metropolitan areas lie wholly within the Cross Timbers, although roughly the western half of the Dallas-Fort Worth Metroplex does, including the cities of Fort Worth, Denton, Arlington, and Weatherford. The western suburbs of the Tulsa metropolitan area and the northeastern suburbs of the Oklahoma City metropolitan area also lie within this area. The main highways that cross the region are I-35 and I-35W going north to south (although they tend to skirt the Cross Timbers' eastern fringe south of Fort Worth), and both I-40 and I-44 going east to west. Numerous U.S. Highways also cross the area. I-35 means a portion of Austin and Travis County is also included in the Cross Timbers.

Interstate 35E (I-35E) is an Interstate Highway in the US state of Minnesota, passing through downtown Saint Paul. It is one of two through routes for I-35 through the Twin Cities of Minneapolis and Saint Paul, the other being I-35W through Minneapolis. Thus, both ends of I-35E are shared with I-35W and I-35.

During the early years of the Interstate Highway System, branching Interstates with directional suffixes, such as N, S, E, and W, were common nationwide. On every other Interstate nationwide, these directional suffixes have been phased out by redesignating the suffixed route numbers with a loop or spur route number designation (such as I-270 in Maryland, which was once I-70S) or, in some cases, were assigned a different route number (such as I-76, which was once I-80S). In the case of I-35 in the Twin Cities area, since neither branch is clearly the main route and both branches return to a unified Interstate beyond the cities of Minneapolis and Saint Paul, officials at the American Association of State Highway and Transportation Officials (AASHTO) have allowed the suffixes of E and W in Minnesota to remain in the present day. I-35 also splits into I-35E and I-35W in Dallas–Fort Worth, Texas, for similar reasons as the I-35 split in the Minneapolis–Saint Paul area.

Interstate 35 (I-35) is a major north–south Interstate Highway that runs from Laredo, Texas near the Mexican border to Duluth, Minnesota. In Texas, the highway begins in Laredo and runs north to the Red River north of Gainesville, where it crosses into Oklahoma. Along its route, it passes through the cities of San Antonio, Austin, and Waco before splitting into two branch routes just north of Hillsboro: I-35E heads northeast through Dallas, while I-35W turns northwest to run through Fort Worth. The two branches rejoin in Denton to again form I-35, which continues to the Oklahoma state line. The exit numbers for I-35E maintain the sequence of exit numbers from the southern segment of I-35, and the northern segment of I-35 follows on from the sequence of exit numbers from I-35E. I-35W maintains its own sequence of exit numbers.

In Texas, I-35 runs for just over 503 miles (810 km), which does not include the 85-mile (137 km) segment of I-35W. It does include the 97-mile (156 km) segment of I-35E. Texas contains more miles of the overall length of I-35 than any other state, almost one-third of the entire length.
