Snow Removal: $45 million (with 175,000 tons of salt used per winter)

 

Mowing: $20.2 million

 

Litter Removal: $5.7 million

 

Signals: Traditional traffic signals cost between $100,000 to $150,000 to install and about $4,100 a year to maintain.

 

Signs: Between 80,000-100,000 signs are needed each year to replace existing signs that are worn out or damaged.

 

These signs are produced by private sign fabricators contracted to provide sign manufacturing services for MoDOT maintenance operations.

 

There are approximately 800,000 signs on the state highway system.

 

Costs for these signs vary because they come in many shapes and sizes, but the

average stop sign costs $400 to make and install.
