Flood Response banner

 

 

A year ago, the Missouri Department of Transportation was putting away its snow removal equipment, when another challenge came its way: in April 2017, the state was hit with severe flooding.

 

At the peak of the flooding, 384 roads were closed. Some routes were under water for days.  More than 3,000 MoDOT employees - many working 12-hour shifts - put in more than 80,000 hours between April 28 and May 31, 2017 on flood recovery efforts.  

 

The Federal Highway Administration provided $2 million of “quick release” funds to jump-start repair work and continue assessing the more than 320 locations throughout the state that sustained damage. MoDOT moved rapidly to reopen roads and bridges and make needed repairs. For example, the department’s response to the closure of I-44 at Hazelgreen, where the asphalt overlay had been peeled away by the flood waters and pushed up against the guard rail, took less than two days. 

 

In Ozark County, the James Bridge on Route PP and the Hammond Camp Bridge on Route CC were washed away by flood waters. By June 29, 2017, construction contracts had been awarded for both structures and the two bridges reopened to traffic on Oct. 11, 2017.

 

The Route PP bridge was replaced at a cost of $2.8 million, and the Route CC bridge cost approximately $3 million to design and construct. Both bridges were built under contracts with Clarkson Construction Company.

 

The new bridge on Route PP was raised an additional four feet, and the Route CC bridge was raised an additional two feet, making it 100 feet longer than the original bridge. The slopes on both bridges were armored with riprap to prevent future erosion around the bridges. Increasing the elevations of both bridges will allow for roadways to remain open longer in the event of future flooding events.

 

The total time of replacement for both bridges was less than six months from flood damage to completion. The accelerated timeline was critical for nearby residents, because nearly all river crossings in the area were either destroyed or impassable.

 

In February, the American Council of Engineering Companies honored MoDOT and the James Bridge project with a Grand Award for quality engineering achievements.

James Bridge replacement on Route PP

 

Accelerated work by engineers and contractors resulted in the replacement of the James Bridge on Route PP over the North Fork River, near Tecumseh, Missouri in Ozark County just six months after it was washed out by flooding in April 2017.

 

The bridge was constructed and re-opened to traffic by mid-October. The accelerated timeline was critical for nearby residents, since nearly all river crossings in the area were either destroyed or impassable.

 

Bartlett & West, an engineering firm with offices in Jefferson City, designed the bridge. Clarkson Construction Co. of Kansas City built the replacement. The company was awarded an emergency $2.6 million contract in July 2017.

 

In recognition of the quality work, the American Council of Engineering Companies recognized the Missouri Department of Transportation and the project with a Grand Award for quality engineering achievements.

The Route PP bridge is 405 feet long and was originally built in 1958.

Flooding Assessments

FHWA and MoDOT engineers have identified damage

at 404 locations including:

  • 207 in the Southeast District

 

 

 

Recovery

 

   
Roads
Bridges
  • On Wednesday, June 21, 2017, Route T below Lake Wappapello in Wayne Co. reopened to traffic after being repaired.



  • Jefferson County Route M
    • UPDATE 6/21/17: A repair plan is in place. An emergency contract will be put out to bid in August with an award expected in September. Once that is done, MoDOT will have a timeline for how long repairs will take and when the road will reopen. More Information

    • Remains closed between Interstate 55 and U.S. Routes 61/67 due to a major slide. The bank along the north edge of Route M is more than 60-feet tall with fractures in the slope at least 30 to 40 feet up. Utility poles are leaning towards and over Route M along with dozens of trees that are more than three feet in diameter. With the threat of rain in the forecast, more earth along with utilities and trees could slide down onto Route M, so it will remain closed. MoDOT staff is working to determine right of way limits and see if temporary construction easements will need to be purchased to make corrections. It is unknown at this time how long this road will remain closed. 


  • UPDATE (August 24): Reynolds Co. Route 106 near Logan Creek located west of Ellington, Mo. is open to two-lane traffic.

  • Two roads closed due to pavement damage.  (Rte. HH below Clearwater Lake and Ozark Co. Rte. JJ)


  • One road closed due to bridge structural damage (Business Route 60, Willow Springs, Howell Co.)

  • One road down to one lane traffic due to pavement damage from a slide. (Shannon Co. Rte. 106)

  • Across the state there are countless locations being examined to determine the spot pavement repairs that need to be made due to flood damage.



  • It will be months before we know the full extent of damage and the cost of fighting the flood and making all repairs.
