That’s the red tip of my shoe for scale at the bottom of the photo with a massive cover from St Paul Fdry & Mfg Co. Probably one of the most massive covers I’ve encountered, maybe 3’ in diameter (why did I stop carrying a measuring tape?). The others I’ve seen that large are a handful of hexagonal ones downtown. This beauty is on the south side of Lagoon just west of Hennepin, on a narrow strip of sidewalk against a flush and boring blank wall that is the undisputed winner on a block where the rest is parking lots with curbcuts whose crossslopes can’t possibly meet ADA standards, let alone basic standards of human decency, and whose sidewalks are suspiciously narrow as well. Without conscious choice, I rarely walk this sidewalk, despite walking parallel to it frequently; the north side of the sidewalk is wider (at least in front of the library), with buildings rather than parking lots, and fewer curb cuts. But no giant sewer covers.
