Driving through Duluth every day, there is so much infrastructure that I take for granted. One of these areas is the "can of worms" interchange in the Lincoln Park neighborhood of Duluth. The area is formally known as the Twin Ports Interchange. This is where highways I-35, I-535 and U.S. 53 converge in a series of curving ramps, elevated freeways and bridges. Most of us have experienced the can of worms only from a moving vehicle. In coming years, the interchange is scheduled to be rebuilt and will not exist in the current format. Changes down the road will mean fewer bridges and more on-the-ground roadway. Recently at dusk, I explored the site on foot to see what I have driven over and past all these years.
