According to Julie Uravich, an engineer with the County,
It consists of post-mounted yellow flashing beacons located on either side of Silverton Road NE and in the new center island. Push buttons mounted on each pole will activate the beacons for a set length of time. The finished product will be nearly identical to the crosswalks on Lancaster Drive NE [pictured]. There will not be any red light indications that you would see with a HAWK installation.Here's the map from the draft bike plan with the priority projects in red. The intersection, one block away from 48th in orange, is marked by the picture of the yellow diamond sign and median.
This part of town is getting some attention. At the Salem Keizer Area Transportation Study Policy Committee meeting next week, a project to design bike lanes and sidewalks on Brown Road will be discussed. 4 other projects may also be discussed. (Look for a post on this next week.)
It will be interesting to see how these fit into a larger vision of mobility, or whether they are envisioned as essentially one-off projects. The crossing at 48th, one block east and also in orange, is not being modified at present.
