Bradshaw's Ferry was a ferry at the crossing point on the Colorado River, of the Bradshaw Trail at Olive City and later at Mineral City and Ehrenburg, between what was then San Diego County, California, and Arizona County, New Mexico Territory.

From 1863, the La Paz - Wikenburg Road connected the Bradshaw Trail to the new mining boom town settlements in the interior of Arizona Territory.

Williams returned to Los Angeles and published an announcement in the Los Angeles Star of the new road between San Gorgonio Pass he had established and of the ferry to the goldfields at the end of the trail.

William Bradshaw himself left operations of the ferry to his brother Issac and died in 1864, officially a suicide, but possibly a murder.
