By the 1920s two canals were built to carry water to farms farther and farther west. Redwood Road was finally rebuilt using concrete making it faster and easier to travel for the mixture of automobiles, wagons, and horses that used it. How Redwood Road got its name has been the subject of much debate but, when there are no redwoods in the valley, the following explanation rings truest. A line parallel to the base meridian was surveyed on the west side of the Jordan River for use in measuring property lines. Redwood stakes that did not decay in the ground were used for the "Redwood Line". It remained the Redwood Line until 1895 when Redwood Road was built as the main thoroughfare for the west side of Salt Lake County. In 1927 the "Pole Line Road" 2700 West was constructed.
