Two men are rescued from a semitrailer that crashed over the side of the Pit River Bridge before it fell into the Sacramento River. Amateur photographer Virginia Schau photographs "Rescue on Pit River Bridge", the first and only winning submission for the Pulitzer Prize for Photography to have been taken by a woman.

A semi-trailer is a trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a semi-trailer truck.

The Pit River Bridge is a double deck, deck truss, road and rail bridge over Shasta Lake in Shasta County, California. The bridge, carrying Interstate 5 on its upper deck and Union Pacific Railroad on its lower deck, was built in 1942 as part of the construction of the Shasta Dam/Shasta Lake reservoir system. The Pit River Bridge was constructed to replace the Lower Pit River Bridge, as the rising waters of the Shasta Lake reservoir would have put the older bridge underwater. The entire bridge spans 3,588 feet (1,094 m) long on the upper deck and 2,754 feet (839 m) on the lower deck. With a height of 500 feet (150 m) above the old Pit River bed, it is structurally the highest double decked bridge in the United States; however, today the bridge sits only about 40 feet (12 m) above the water when Shasta Lake is full.

The Sacramento River is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about 26,500 square miles (69,000 km²) in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento.

Virginia Margaret (Brown) Schau was an American who was the first woman and second amateur to win the Pulitzer Prize for Photography, which she was awarded in 1954. The award-winning photograph was taken in Redding, California, at the Pit River Bridge and was titled "Rescue on Pit River Bridge". The photograph was taken with a Kodak Brownie camera.
