As we move into early 2025, significant progress has been made on the new Mississippi River Bridge being built at Lansing, Iowa. Despite winter weather, which has remained relatively mild, construction crews have been able to advance at a steady pace, thanks in part to favorable conditions and efficient work by Kraemer North America.

Bridge Structure Taking Shape

On the Wisconsin side of the river, the bridge's foundation is coming together with the completion of three piers and the abutment. Kraemer North America recently set three beams, each measuring over five feet tall and 121 feet long, with a weight of 106,500 pounds per beam. These beams were brought in from Midwest Precast Concrete in Mt. Pleasant, marking a major milestone in the project. In total, there are 15 beams now in place, which are essential for the next steps in construction.

With the beams now set, attention will soon turn to the next phase: decking. This involves placing forms for the bridge deck and reinforcing the structure with steel. Concrete pouring is expected to begin around mid-April, which will significantly progress the project.

Work Continues on the Water

While the weather has been somewhat mild, it’s still been cold enough to freeze the Mississippi River, presenting challenges for the construction team. A tugboat and barge have been in use to keep the water navigable, allowing workers and materials to reach the site throughout the winter months.

The primary focus on the river is at pier two, where work on a coffer cell is underway. This structure will create a dry workspace for the crew as they build the footing of pier two. Once completed, this footing will be crucial in maintaining the stability of the bridge, ensuring it can withstand potential impacts from passing barges.

Meanwhile, on the Iowa side of the river, the contractor is continuing work on pier one. Drilled shafts are being constructed at this site, with each shaft being 11 feet wide and extending 45 feet deep. After drilling, the shafts are cleaned and reinforced with a rebar cage before being filled with concrete. These three shafts will form the foundation for the footing of pier one.

Looking Ahead

As the weather warms and work progresses, the construction team is on track to continue with the next stages of the bridge's development. From the addition of the decking to the completion of the piers and footings, this bridge will soon take its final shape, providing a vital connection across the Mississippi River.
