Write Up:

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

Compared to the 2025-2029 Statewide Transportation Improvement Program investment of $10.744 billion, the 2026-2030 STIP investment decreased by 9.76% to $9.695 billion. The current STIP is estimated to create 9,526 jobs annually which is a decrease of 968 jobs or 9.22% 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 $28.9 billion of economic output during the next 20 years, resulting in a $3.00 return on every $1 invested in transportation. This increase of 1.08% is attributed to the total outlays supporting impacts decreased by a greater portion that the decline in the cumulative 20-year output, resulting in a higher per dollar value. Missourians have consistently said they want MoDOT to take care of the existing system first, a $63 billion value that carries a $171 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.
