The Historic Sidewalk of Portland

For the last 6 months or so [year as of 1/15] I have endeavored to take a picture of every square of sidewalk I have seen with the imprints of date it was constructed and and the name of its construction company. It turns out there a lot of people were putting in sidewalk. I first became interested in the sidewalk while researching the history of a mysterious butte in East Portland. Of course the horse carriage rings in the curbs of Portland sparked my imagination long ago. If anybody wants to contribute, I have been using #historicsidewalk on instagram. I should have kept better note of the locations of these. As it is, I will describe where I remember them being.
