Look Both Ways
This is an unusual one, mostly for the way it’s presented. It’s got a nice aesthetic, and could be mistaken for an art installation. It’s in the median, at a 2-stage crossing where a trail meets a busy road. To cross the road, you have to cross one lane to get to the sign, turn right and walk down the median, where there’s another similar sign that says “WAIT FOR GAP,” and then there’s an outlet from the median to let you cross the other lane. So the geometry of the crossing kind of emphasizes the warning.
The sign is located on Pottery Rd. in Toronto, where the DVP trail crosses.
