Drilled Shafts Complete at St Croix

Pier 9 FootingAs reported by the Minneapolis Star Tribune, Case Foundation recently finished constructing 40 drilled shafts at the St Croix River Crossing Project.  Since early June, Case has been working at a feverish pace to construct the drilled shaft foundations for the new extradosed bridge between Minnesota and Wisconsin.  As of November 8th, all of the drilled shafts are officially complete.  General contractor Kramer is working to finish the pier footings and support tower bases by early 2014.  Soon, the joint venture of Lunda and Ames will begin construction of the $380 million bridge superstructure.

As MnDOT’s foundation consultant for the project, DBA has been on site during much of the foundation construction over the past five months.  Some pictures taken during this time, along with several pictures from MnDOT are available for viewing on our Picasa Page.  More pictures and information can be found on the project website and Facebook Page, and the project can be viewed live via webcam.  Previous DBA blog posts about the main project and the predesign load test program can be found here.

DBA is pleased to wrap up its role on the St Croix Crossing Project with a very positive outlook.  The drilled shaft construction proceeded on schedule and as planned without unexpected challenges, and our strong client relationships with MnDOT continued to grow stronger.  It was also nice to see familar faces from Case, Braun Intertec, and Parsons Transportation Group, many of whom we worked with us at Hastings.  We very much look forward to working with these partners again in the future!

Missouri Bridge Project Updates–Hurricane Deck and MRB

Time for a quick update on two projects owned by MoDOT on which DBA was involved.

First, the official opening of the Missouri Route 5 – Hurricane Deck Bridge Replacement was held on September 7th.

Hurricane Deck

History was made on Sept. 7, 2013when state and local officials cut the ribbon on the new Hurricane Deck Bridge during a ceremony held in the center of the new structure.  The bridge officially opened to traffic in the late evening on Monday, Sept. 9. The original bridge is now closed and will be prepared for demolition during the remainder of 2013. Final demolition will take place in the spring of 2014.

Check out this time lapse video of the bridge being built.

 

Last, the new Mississippi River Bridge in St. Louis.

They have closed the gap on the bridge – lots of neat photos here showing the final deck panels in place.  Here they are placing the final edge girders.  Finally, here is a link to the live construction cameras.
