Smooth zipper merging doesn’t happen by accident—there will be signs. But how many and which ones? ⁠ A recent paper studied real-world freeway work zones to evaluate how different combinations of static and electronic message signs influence driver lane use and merging behavior under zipper merge control. ⁠Learn how strategically placed electronic signage can be used to improve driver compliance and make zipper merges function more smoothly in work zones: go.asce.org/4u23iVn.

The world’s 1st and only rotating boat lift officially opened #OTD in 2002. Taking the shape of a Celtic-inspired, double-headed axe, the Falkirk Wheel now connects two historic canals in central Scotland—but its story begins centuries earlier.⁠ When it was completed in 1790, the 35-mile Forth & Clyde Ship Canal was the world’s deepest sea-to-sea canal, linking the North Sea and Irish Seas. Later joined by the 31-mile Union Canal by an impressive flight of 11 locks, both canals fell into decline and, by the mid-20th century, were closed, severed or blocked at more than 30 locations.⁠ What followed was not simply restoration, but reinvention. The result: A 115‑foot rotating lift with 2 arms to carry gondolas with water‑filled caissons—each holding up to 66,000 gallons and up to 4 boats—moving vessels between the aqueduct and the basin in about 15 minutes. Recognized as a joint ASCE / @ICE_engineers Landmark, the Falkirk Wheel showcases how past ingenuity and modern engineering can deliver enduring social, economic and environmental benefits. Explore the history and engineering behind the remarkable innovation—free on @ASCEpublishing's #ASCELibrary now through May 31: go.asce.org/4tBXUqT. #VisitASCELandmarks
