These marks and measurements starting appearing on the cherished arches of the Los Angeles Sixth Street Bridge this past week. We think that this could be marking the cut marks for their removal.
So far we don’t know what’s going to happen to the arches. Hopefully the metal can be reused for new fixtures, and thus kept on site with new life and significance.
This past week the city contractors also took down the original dedication plaque for the Sixth Street Viaduct.

On the morning of Wed, July 29, 2015 the dedication plaques were removed. Photo credit: Zero-Renton Prefect
