Photograph of Arroyo Seco at Avenue 52 before installation of channel, ca.1938. The concrete bridge spans the river at center. The shallow, muddy arroyo runs from the foreground at right to the background at left. Utility wires can be seen at left, and a brushy hill is visible at right. Light posts are visible along the roadbed of the bridge. This new bridge was washed out in the flood of March 3, 1938.
Photograph of the new bridge over Arroyo Seco at San Pascual Avenue, replacing the wooden structure destroyed by the flood in March of 1938, ca.1939. Several boulders and small plants sit amongst the small rocks which blanket the right river bank in the foreground. The river flows from the left foreground to the right distance with the San Pascual Avenue Bridge extending over it at center and a walkway over it in the background. Electrical poles line the sides of the bridge while trees line either bank.
Photograph of Arroyo Seco Channel north of Avenue 52 at beginning of work on Arroyo Seco Parkway, ca.1940. The concrete channel curves from the foreground at right towards the background at left. Small buildings can be seen along the river at right, and wooden scaffolding is visible across the channel in the background. Tall trees line the channel on both sides, and a brushy mountain can be seen in the distance at right.
