A major point of interest on the East Fork is the Bridge to Nowhere , a high concrete arch bridge that was once part of the East Fork Road before the rest of the road was destroyed by flooding in 1938 . The East Fork Road was originally intended to connect the Los Angeles Basin to the Angeles Crest Highway , but was never completed due to the high cost of cutting and tunneling through the rugged East Fork Canyon . A later attempt to build a road through the East Fork via Shoemaker Canyon , in the 1950s , was also aborted due to lack of funds
