DCCI completed the erection of the BNSF two track lift span bridge that replaced the existing swing span bridge which stood for 119 years in Burlington, Iowa.  The new bridge, spanning 350 feet, doubles the width of the boat traffic navigation channel on the Mississippi River.  The truss steel weighs about 4.2 million pounds.  The weight of the Towers is 410 tons and counterweights are 255 tons.  DCCI also set the machinery to run the lift span. 

The replacement truss was erected on four barges floating on the ever-changing Mississippi River.

One highlight of this project was the float-out of the old swing span bridge and float-in of the new lift span during a 30 hour shutdown of train traffic the week of Christmas.  The work started on a Monday morning at 1:00 a.m., and as the Ames crews accomplished the float-out, Danny's Construction crews had to remove one set of the jump spans, rework the bearings, turn the girder spans around and reset them, and successfully float-in the new truss, landing it on the bearings.  This work was accomplished in frigid weather using three cranes mounted on barges, numerous barges supporting the work, and a team of tug boats to position the work and move equipment and people.  

The next milestone achieved was the successful lifting operation of the bridge in time for river traffic.  We are very proud of the accomplishments of our team on this project!
