Last week construction crews lowered a 300’ long, 1.2 million pound steel span of the old westbound Interstate 90 Dresbach bridge 70 feet down to a barge in the Mississippi River. This was the second span to be lowered. Last month, crews lowered the eastbound span of I-90. Traffic on the river’s navigational channel west of La Crosse, Wisconsin, was closed while the beam was lowered. To lower the beam, crews used a frame lowering system which used jacks to lower the span at a rate of 30 inches each 15 minutes.

Westbrook was on site for the lowering of the eastbound span.

At the piers, the girders are 22’ deep, which are some of the deepest steel bridge girders in the country.  Two 10’ long pieces of the girders will be preserved at Purdue University’s Steel Bridge Research, Inspection, Training, and Engineering Center, S-BRITE.

Please join me in extending best wishes to Jim Geishirt, who is retiring from Westbrook on May 31st after devoting 26 years to being a productive team member as a Civil Engineering Technician. Jim will be greatly missed by staff and clients alike. We have all benefited from his dedication, knowledge, and hard work. Jim was always the one to step up to the plate when even the smallest tasks needed to be done whether that be for a project or around the office. He will be sorely missed and not easily replaced.
We know you all join us in wishing Jim well as he starts a new chapter in his interesting life. We know he is eager to catch up on the traveling and sailing he loves so much.
