#6, Hawthorne Bridge, focus on the circle between the eastbound & the westbound ramps and/or the intersections of the ramps with the surface streets

On such a sunny day, working outside with a task one could accomplish must have been a rewarding activity.
I took this photo later in the day from when I took the photo on Monday's post, a little over four hours later. A crew poured the rest of the sidewalk on the inner edge of the circle. The white truck is pulled to the curb on SE MLK, which is a one-way street, southbound. The bridge ramp above it is the eastbound exit ramp of the Hawthorne Bridge. The Ross Island Sand & Gravel truck is pulled to a stop on the circle. The man on his knees is creating a recess for the installation of the yellow vinyl section of truncated domes, that rectangle that looks sort of like permanent, wide-spaced, opaque, yellow bubble wrap which you see along the edges of subway stops and in the handicapped ramps from sidewalks down to street level. Truncated domes, which meet ADA requirements, serve as a detectable, tactile warning surface for the visually impaired. I myself like to stand on them at corners while I wait for the light to change, unless there is a visually impaired person there, too. My feet enjoy the massage. You can see what looks like two pieces of yellow, one on each side of him as he scrapes and smooths. I for one am glad to see that the sidewalk is as high off the surface of the circle as it is--I doubt that rain will stand on that sidewalk, ever.


The truncated domes matt has been installed, near the end of the plank the man is standing on near the bottom center of the photo. Now these men are continuing to finish the sidewalk's surface. The man on the left is using a pad attached to the extended-length handle. The other two men are on their knees, smoothing by hand.

In this photo you see more finishing work in progress. The man walking on the plank is crossing back to the street because he has finished using the extended-length handle and pad on the concrete. And you can see the slightly different colored rectangle to the left of where steps, there in the gray concrete. That is the truncated dome matt. The planks that cross from one side of the sidewalk to the other were moved to the right a few feet, and the work continued.

Glad to see them installing nice wide sidewalks. Walking is the best way to take in a city.
