Bridge Closures

Unplanned Bridge Closures and Restrictions

 

As Missouri’s bridges continue to age and deteriorate, it is sometimes necessary to close bridges unexpectedly due to problems revealed during routine inspections.  The following is a list of unplanned bridge closures since January 1, 2014.  The list is updated as new information becomes available. Click the link to see the MAP locations of all unplanned bridge closures and restrictions.

bridgeAbout Missouri’s Bridges

MoDOT is responsible for maintaining nearly 10,400 bridges on the state system.  The average age of our bridges is 44 years and most of them were designed to last 50 years. More than 1,600 of our bridges are more than 75 years old, and about 5,000 are 50 or older.

 

We currently have 641 bridges that are considered to be in critical condition, up from 591 in 2014. About 50-100 fall into that category each year. Bridges are rated on a nine-point scale, with 9 being a new bridge and 2 being a closed bridge. Missouri’s critical condition bridges carry either 3 or 4 ratings.

 

To replace all of these bridges would cost in excess of $820 million, and that is simply not possible with current transportation funding.

 

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 1,400 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.
