At the June 13, 2012, Mayor’s Bicycle Advisory Council meeting, we asked Mike Amsden if the Wells Street “enhanced” marked shared lane would be accompanied with signs that say “bikes may use full lane”. He said “no”.
Things changed, as photo contributor Adam Herstein noticed this morning. He says this sign is posted at each intersection (from Wacker Drive to Van Buren Street, we presume, which is the length of the “enhanced” marked shared lane).
A larger version of this sign exists, but the unique situation of the ‘L’ track colums might prevent objects from exceeding the column width, unless they were higher up to avoid being smashed by trucks.
