Engineers and crew with the Oregon Department of Transportation connect about 10 electrical sensors at critical areas on the underside of the Bridge Street bridge Tuesday morning. Tests were being done to determine the present load capacity of the bridge. Flaggers directed traffic safely through the area until early afternoon. Sensors would reveal the amount of stress bearing down on concrete and steel from an ODOT truck loaded with about 50,000 pounds of rock, according to John Snyder, an ODOT employee. Wires connected sensors to laptop computers on shore, where engineers accumulated data to be reviewed later at their Salem office.
