Pictured are crews installing a temporary signal near the North Fabius River bridge on MO 16 west of Monticello in Lewis County to restrict traffic to one lane on the bridge.
North Fabius Bridge on Missouri Route 16 just west of Monticello has been reduced to a one lane bridge with temporary signals in place. Just down the road, the bridge over the Middle Fabius River also on MO 16 has been load posted with a restriction of 15 miles per hour for any trucks over 21 tons.
The North Fabius and Middle Fabius River bridges are 84 years old and during a routine inspection, MoDOT officials found structural deficiencies in these bridges. Every bridge constructed goes through a natural deterioration or aging process, although each bridge is unique in the way it ages.The fact that the bridge is classified under the federal definition as "structurally deficient" does not imply that it is unsafe. A structurally deficient bridge, when left open to traffic, typically requires significant maintenance and repair to remain in service. Structurally deficient bridges are often posted with weight limits to restrict the gross weight of vehicles using the bridges to less than the maximum weight typically allowed by statute.
Besides these two bridges, we also have bridges that have been impacted by inspections in Scotland, Pike and Macon Counties.
