bridgeAbout Missouri’s Bridges

MoDOT is responsible for maintaining nearly 10,400 bridges on the state system. The average age of our bridges is 46 years and most of them were designed to last 50 years. Sixty percent of Missouri’s bridges are beyond their original intended life.

We currently have 866 bridges that have been rated “poor” by the Federal Highway Administration. Each year about 100 bridges fall into the “poor” category, and we fix or replace about 100. The number of poor bridges in Missouri, though, is rising steadily as we struggle to hold our own.

Bridges are rated on a nine-point scale, with 9 being a new bridge and 2 being a closed bridge. Missouri’s poor bridges carry a rating of 4 or less.

This situation is symptomatic of where we are. We have the nation’s 7th largest system of roads and bridges but our funding comes in at 47th in the nation. We can only stretch our dollars so far, and must prioritize our work.

 

The stark reality for bridges in our current funding situation is that more of them will be weight restricted, some will need to be closed, and the economic vitality of our state and mobility of our citizens will be compromised.

A Thorough Inspection Process

All bridges are inspected regularly in accordance with federal law, typically every two years. If a bridge has known problems, it is inspected more frequently. If a bridge is open to traffic it is safe; however, as our bridges age and deteriorate, we are having to close them more often.

 

Almost 1,300 of our bridges are load-posted which means they are unable to carry some normal traffic. Examples of what some common vehicles weigh are shown in the graphic to the left.  Click the graphic to see full-size infographic.
