Write Up:

Investment in transportation improvements has long been recognized as a major economic engine that drives growth in job creation, personal income, and new value added to Missouri’s economy.

Compared to the 2026–2030 Statewide Transportation Improvement Program (STIP) investment of $9.695 billion, the 2027–2031 STIP investment decreased by 7.88% to $8.931 billion. The current STIP is estimated to create 9,303 jobs annually, which is a decrease of 223 jobs, or 2.34%, from the previous STIP. The average number of jobs created decreased largely due to the higher than average estimated job creation expected from the I 70 improvements.

Transportation investments are expected to contribute approximately $28.3 billion in economic output during the next 20 years, resulting in a $3.18 return for every $1 invested in transportation. This increase of 5.99% is attributed to total outlays supporting impacts decreasing by a greater proportion than the decline in the cumulative 20 year output, resulting in a higher per dollar value. Missourians have consistently stated they want MoDOT to take care of the existing system first—a $66 billion asset with a $173 billion replacement cost.

Purpose of the Measure:

This measure tracks the economic impact resulting from the state’s transportation investments.  

Measurement and Data Collection:

MoDOT works with HDR, Inc. to perform economic impact analyses for the state’s transportation investments. The analyses are performed using mode-specific templates in Excel and economic multipliers from a model called the Impact Analysis for Planning (IMPLAN). These results demonstrate a strong link between transportation investment and economic development.
