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.
Photograph of a view of the Arroyo Seco Park and Channel looking northeast after the construction of the Pasadena Freeway, ca.1941. The four-lane freeway is at right and is divided by a dirt median. Three automobiles can be seen traveling on the road. The Arroyo Seco Channel is at left and runs parallel to the freeway. A tractor is visible in the dirt near the edge of the channel at left. Several tall, thin trees can be seen around the road, and the Marmion Way/Avenue 64 Bridge appears in background. A tall hill can be seen in the distance at center. Compares to CHS-14548, showing the pre-construction view.
