Engineers dredged 500,000 cubic yards of sand from the Mississippi River and used it to build seven islands; six years later, the $25 million McGregor Lake project has restored 270 acres of aquatic habitat and protected 22 acres of wetlands

For years, sand dredged from the Mississippi River was removed to keep one of America’s most important waterways navigable. At one restoration site, engineers found another use for that material, building islands. The US Army Corps of Engineers has completed a $25 million habitat restoration project at McGregor Lake in Wisconsin, where about 500,000 cubic … Read more

A 1950 Washington bridge carrying about 90,000 vehicles a day is getting a $114 million overhaul; engineers will replace its movable span with a fixed one floated into place during a single 56-hour closure

A 1950 Washington bridge carrying about 90,000 vehicles a day is getting a $114 million overhaul; engineers will replace its movable span with a fixed one floated into place during a single 56-hour closure

As per the report, engineers will use accelerated bridge construction methods to limit disruption to one of the region’s busiest transportation corridors. A bridge that has carried Washington traffic for more than seven decades is headed for a major transformation, but commuters may barely notice the most dramatic part of the work. The nearly half-mile-long … Read more
