My route starts off near the Auburn Mall on Pakachoag Road where the town has installed this anti-bicycle road grate.
we have one near me on Route 27 as it crosses over Route 2 in Acton, that I should report. it's the only one of it's kind that I ever see on Route 27. from casual passing observation, it looks square, so might be an easy fix to just rotate it 90 degrees
there's only 1 & it's on the East bound travel lane of 27, heading toward Boston
