Flood of 2019:D&I/Milw Bridge Washouts by Big Sioux River

D&I = Dakota & Iowa

T-648: (Bridge Hunter; no Historic Bridges; John MarvigSatellite)

Bill Neill shared Civil Design post
The D & I Railroad Bridge T-648 Reconstruction project is underway. The General Contractor, L.G. Barcus & Sons, Inc., started work on June 12 and has completed access road construction, clearing, partial structure removal, and the start of the temporary causeway at the north end of the project. Riprap and access road material was provided by L.G. Everist, Inc. via 42 railcars. With recent permitting approvals for work to take place within the Big Sioux River, the contractor will be kicking it into higher gear this week with additional railcar deliveries of riprap for temporary causeway construction. Like the Civil Design Inc. page for more updates throughout construction!

In 2016, several of the bridges were replaced. I have not been able to determine if any of the new ones sustained damage.
Hawkins removed and replaced eight separate bridges over two projects. Existing bridges were timber and replaced with H-pile supported precast structures that varied in lengths from 22 feet up to 100 feet. Pile driving was coordinated around train traffic and each bridge superstructure was completely replaced in a one-day track outage. Construction duration for all eight bridges was 5 months.

I'm too lazy to locate these on a satellite map and in Bridge Hunter.

Construction update on the D & I Railroad Bridge T-648 Reconstruction Project: LG Barcus and Sons, Inc. began driving HP 14x89 pile on Monday at the north end of the bridge and have successfully driven pile for the north 2 substructures. Next week, the causeway is expected to continue to be built on the south end of the Big Sioux River along with continued pile driving.
ARC Fabricators has the first steel span complete and ready for delivery, scheduled for Tuesday, July 9! A total of 3 steel spans and 5 precast concrete double box beam spans will be installed. Precast elements will be ready for delivery as well once the Contractor has all pile driving completed. Like Civil Design Inc. for future construction updates!

LG Barcus and Sons, Inc continues to push forward through the rise in the Big Sioux River, continuing with pile driving operations and the setting of the first few precast substructure units and the northern Prestressed Box Beam span. ARC Fabricators completed the first steel span fabrication and was delivered to the site Tuesday evening. Progress! LG Everist, Inc. South Dakota Department of Transportation

We are pouring the last CIP pile bent for Civil Design Inc and D&I Railroad.
Thank you P-TN for the photograph!

On March 15, 2019, the D & I Railroad lost a bridge over the Big Sioux River in Canton, SD to a flood event, causing complete failure to the structure. On August 15, five months to the day after the catastrophic flood, the new bridge was safe for train operations! On August 19, the D & I Railroad ran their first revenue train from LG Everist, Inc. in Dell Rapids, over the new bridge in Canton and onto its final destination of Sioux City, IA. This milestone could not have been achieved without the outstanding work completed by the Contractor, LG Barcus and Sons, Inc A huge thanks to everyone involved throughout this project, it took an army. Glad to have you back up and running D & I Railroad! South Dakota Department of Transportation

CDI posted three photo with the comment: "One of the five D&I Railroad operated bridges CDI designed repairs for following last March's flooding event was Bridge T-572 near Hawarden, IA. It had sustained structural damage requiring the replacement of six bents and the track structure it supported. Construction began in April and was completed by May 2019."


CDI posted a before and after photo as part of a presentation announcement about their 5-month reconstruction of Bridge T-648.
