Bill to Rename US-287 as Interstate 47
U.S. Senator John Cornyn (R-TX) introduced the I-47 Future Interstate Act on Monday. The legislation would redesignate the roughly 1,791-mile U.S. Highway 287 as Interstate 47 and name it the “Trump Interstate.” Senator Cynthia Lummis (R-WY) is listed as a co-sponsor.
Corridor Overview and Economic Projections
US-287 runs from Port Arthur, Texas, on the Gulf Coast to Choteau, Montana, crossing Texas, Oklahoma, Colorado, Wyoming and Montana (one source adds Idaho). It is the second-longest three-digit highway and moved over 923 million tons of freight in 2022. A July 2025 Texas Department of Transportation feasibility study projects $5.4 billion in travel-cost savings, a 161 % return on investment, a 28 % crash-rate reduction, creation of 46,885 jobs (? 47,000 in other reports) and $11.6 billion annual GDP gain by 2050.
Political Context and Stakeholder Positions
Cornyn is campaigning in a Republican Senate runoff against Attorney General Ken Paxton and is seeking an endorsement from former President Donald Trump, who has not yet announced a position. Cornyn’s public statements frame the bill as a means to boost growth, improve safety and honor “the most consequential president of our lifetime.” Lummis’s co-sponsorship signals broader Republican support, while the TxDOT study provides the economic rationale cited by the sponsor.
Conflicting Reports & Gaps
Sources differ on the number of states traversed—five versus six (including Idaho). Job creation estimates vary between 46,885 and “roughly 47,000.” One report cites a $24.52 billion construction cost, while other sources focus on projected savings without a total-cost figure. Trump’s endorsement remains pending, leaving the political impact uncertain.
