Interstate 30 in Texas Interstate 30 is an east–west Interstate Highway corridor traversing the Dallas–Fort Worth metroplex and extending eastward to Texarkana, linking major Texas urban centers, industrial districts, and transportation nodes. The route connects Fort Worth, Dallas, Garland, Mesquite, Rockwall, Greenville, Sulphur Springs, Mount Pleasant, Longview, Marshall, and Texarkana, serving as a primary arterial for passenger, freight, and commuter traffic. It parallels historic U.S. Route 67 and integrates with significant corridors including I‑20, Interstate 45, Interstate 35W, and Interstate 635.
Route description
I‑30 begins at an interchange with Interstate 820 and U.S. Route 377 in Fort Worth near the junction with U.S. Route 287, threading along the Trinity River floodplain and passing near Tarrant County College, University of North Texas Health Science Center, and the Fort Worth Stockyards National Historic District. Entering Dallas County, I‑30 traverses central Dallas on the S.M. Wright Freeway and the Stemmons Freeway corridor, intersecting with I‑35E and providing access to Dallas Love Field, Fair Park, Dallas Farmers Market, and the Dallas Arts District. East of downtown, the highway follows the Trinity River and crosses the Red River basin into Rockwall County, serving suburban communities such as Garland and Mesquite and connecting to SH‑66 and U.S. Route 80. Further east the route passes through Hunt County, Kaufman County, and rural counties, intersecting with U.S. Route 69, U.S. Route 271, and U.S. Route 259 while providing access to Lake Tawakoni, Caddo Lake National Wildlife Refuge, and the historic districts of Longview and Marshall. Approaching Texarkana, I‑30 merges with federal and state arteries near State Line Avenue and terminates at the Arkansas state line, connecting to Interstate 49 and U.S. Route 71 corridors.
History
The I‑30 corridor overlays segments of historic U.S. Route 67 and U.S. Route 80, corridors used since the early automobile era for routes between Fort Worth and Little Rock. Initial Interstate planning in the 1950s under the Federal-Aid Highway Act of 1956 designated the route as part of the national network, with construction milestones tied to the growth of Dallas–Fort Worth International Airport planning, regional industrial expansion around Downtown Dallas, and military logistics connected to Naval Air Station Dallas (formerly Hensley Field). Major segments opened during the 1960s and 1970s, including the urban stretches through Fort Worth and Dallas, later realignments reduced grade crossings and improved interchanges near Garland and Rockwall. In the 1990s and 2000s, reconstruction projects added managed lanes and reconstructed interchanges to serve increased commuter flows from Plano, Frisco, and McKinney suburbs. Preservation and rehabilitation efforts have involved partnerships with Texas Department of Transportation, regional planning organizations such as the North Central Texas Council of Governments, and federal programs administered by the Federal Highway Administration.
Major intersections
Key interchanges along I‑30 include junctions with I‑820 and U.S. Route 287 in Fort Worth; the concurrency and splits with I‑35W and U.S. Route 67 near central Fort Worth; the downtown Dallas junctions with I‑45, I‑35E, and I‑635; eastern connections with U.S. Route 175 toward Kaufman County, intersections with U.S. Route 69 at Greenville, U.S. Route 271 at Mount Pleasant, and the junctions with U.S. Route 259 and U.S. Route 80 near Longview. Near Marshall, I‑30 meets state routes including U.S. Route 59 and historic US‑80 overlays; in Texarkana the route ties into Interstate 49 and U.S. Route 71, forming a multimodal interchange that links Texas, Arkansas and broader U.S. Route 67 corridors.
Service and auxiliary routes
I‑30’s auxiliary and service routes include spur and business routes that connect downtown cores and bypasses: Business Loop 30 through Greenville, business routes serving Sulphur Springs, Mount Pleasant, and Longview, and service interchanges providing access to DFW Airport via connector routes. The corridor is supported by parallel state highways such as SH‑121, SH‑205, Loop 12, and President George Bush Turnpike which distribute local traffic. Regional transit agencies including Dallas Area Rapid Transit, Trinity Metro, and Amtrak stations near Longview and Marshall provide multimodal links; freight connections involve facilities of Union Pacific Railroad, BNSF Railway, and regional intermodal yards.
Future developments and improvements
Planned projects coordinated by Texas Department of Transportation and metropolitan planning organizations include managed-lane extensions, interchange reconstructions at major nodal points such as I‑35E and I‑45 junctions, and corridor widening to accommodate projected growth in Collin County and Rockwall County. Proposals tied to state and federal funding initiatives aim to improve resilience against flooding in the Trinity River basin and to integrate Intelligent Transportation Systems sanctioned by the Federal Highway Administration and regional tolling authorities. Long-range plans reference expansion near Royse City, environmental reviews involving U.S. Fish and Wildlife Service habitats, and freight-improvement grants supporting connectivity to Port of Longview-style facilities and inland logistics hubs.
Traffic and safety statistics
Traffic volumes on I‑30 vary from urban peak volumes in Dallas and Fort Worth—with Average Annual Daily Traffic counts monitored by TxDOT—to lower rural counts east of Sulphur Springs. Crash rates have prompted safety campaigns coordinated with National Highway Traffic Safety Administration initiatives, including median-barrier installations and improved signage following studies by the Texas A&M Transportation Institute. Freight share and commuter percentages reflect interaction with regional employment centers like Downtown Dallas, DFW International Airport, BNSF intermodal terminals, and energy-sector facilities. Congestion management strategies leverage park-and-ride lots served by DART Rail expansions and express-bus services to reduce single-occupancy vehicle trips.
