The notation on the back of the photo reads "IT [sic] Truck on left gets ready to pump acid from leaking truck on right I680 & 84 IT [sic] workmen at right use soda ash to mop up spilled acid." The two tucks described in the notation are the focus of the photo. They appear to be directly under highway road direction signs, the one at left indicating 680 to Fremont and San Jose, the other at right pointing to Highway 84 to Calaveras road and Dumbarton Bridge. An exit sign is at right, and close by that sign the two men are mopping up the spilled acid with soda ash. Fumes dominate the background.
