On November 6, 2018, Missouri citizens will vote on Proposition D, a general election ballot measure which, if approved, would provide the state with approximately $412 million annually and the City of Creve Coeur approximately $200,000 annually in funding for road construction and maintenance. 

Proposition D would increase the motor fuel tax by two and one half cents per gallon annually for four years beginning July 1, 2019. Once fully implemented, the measure would generate approximately $288 million annually providing funding for Missouri state law enforcement and maintenance for highways, bridges, roads and streets, as well as $123 million annually to local governments for road and bridge construction and maintenance.

The average driver will spend an additional $1.28 per month on gas after the 2.5 cents increase during the first year. By the fourth year, after the full 10 cents increase has been implemented, the average drive will spend an additional $5.10 per month. The current motor fuel tax rate is 17 cents per gallon in the state of Missouri and has not been increased since it was first established in 1996.
