Write Up:

Missourians have repeatedly told MoDOT that keeping roads smooth is a top priority. Over the years, MoDOT has been able to fund pavement improvement projects on thousands of miles of state highways.

MoDOT maintains 33,859 miles of highway. The percent of highways in good condition are: major roads at 92%, minor roads at 80% and low volume roads at 74%.  Major, minor and low volume highways have met the statewide target in the past five years. As defined by FHWA, the target is based on the statewide asset management plan and represents MoDOT’s goal of maintaining current condition.

Beginning in 2018, the Federal Highway Administration required all Departments of Transportation to report pavement data related to the structural integrity of the pavement, which may not impact current pavement smoothness but may cause future pavement issues. The current percent of major highway pavements in good structural condition is 67%.

MoDOT has implemented asset management practices statewide to invest in transportation projects that will keep good roads in good condition.

Purpose of the Measure:

This measure tracks the condition of Missouri's highways.

Measurement and Data Collection:

Missouri’s major highway system contains the state’s busiest highways, including interstates and most U.S. routes. There are 5,546 total miles on the major highway system.

Missouri’s minor highway system consists of its less-traveled state highways, including most lettered routes and routes that mainly serve local transportation needs. There are 17,166 miles of minor highways in Missouri.

Missouri’s low volume highways are those state owned roads with less than 400 cars traveling on them per day. There are 11,147 miles of low volume roads in Missouri.

Missouri measures the condition of its roadways using smoothness as one factor but also considers physical distresses, such as cracking.

The targets for this measure are set by internal policy and will not change unless policy changes, regardless of performance.
