A Missouri House committee has endorsed a proposed 1-cent increase in the state sales tax to boost funding for transportation.
The proposed amendment to the Missouri Constitution would require approval in a statewide vote and expire after 10 years.
Proponents estimate the higher sales tax would raise nearly $8 billion over 10 years for transportation projects.
The measure would dedicate 10 percent of the extra revenue to local transportation needs and freeze the state's gas tax rate while the higher sales tax was in effect.
