Untangling the triangle

摘要

If it's a weekday you can bet there are over 150,000 people in Kansas City, Mo., barely moving on a couch. The Grandview Triangle Interchange, where I-435, I-470 and Highway 71 meet in a tangled mess, is perhaps the most outdated of its kind. Containing three merging freeways and as many as 64 movements, the thoroughfare is struggling to move its daily numbers, which could reach as high as a quarter of a million in 10 years. The Missouri Department of Transportation recently decided to give the Triangle a shapelier figure, but there was little room to expand the waistline.
