Can of Worms (interchange)

The Can of Worms is a local name for the intersection of Interstates 590 and 490 on the east side of Rochester, New York. Since the intersection was rebuilt from 1988 to 1991, the name has fallen into disuse, but from the time of its construction until then it was a major source of comment locally for its effect on traffic.

Local legend relates that on viewing the plans for the original interchange, an engineer named Stanley Kozak was heard to exclaim "It's like a !". The term came into common use, probably via local media, and eventually was marked on local streetmaps.

Paradoxically, the new intersection is actually more complex than the previous one, in the sense that there are now more ramps connecting the two highways than before. However the rebuilding realized major benefits as follows:
* Traffic proceeding east-west on I-490 was required to merge across I-590 traffic in order to continue on the same highway. This was eliminated. There was a corresponding benefit for I-590 traffic.

The Interstate 35/Interstate 535/U.S. Route 53 interchange in Duluth, Minnesota is also known locally as the Can of Worms and features a pair of left exits from I-35, a stoplight, and lane drops over the I-35 bridge.
