in 1895.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 11. This agency consisted of three commissioners who were charged with analyzing the roads of the state and making recommendations for their improvement. At the time, there was no state highway system, since roads were purely a local responsibility. California's roads consisted of crude dirt roads maintained by county governments, as well as some paved streets in certain cities, and this

After the commissioners submitted their report to the governor on November 25, 1896, the legislature replaced the Bureau with the Department of Highways.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 12. Due to the state's weak fiscal condition and corrupt politics, little progress was made until 1907, when the legislature replaced the Department of Highways with the Department of Engineering, within which there was a Division of Highways. California voters approved an $18 million bond issue for the construction of a state highway system in 1910, and the first

began requiring vehicle registration and allocated the resulting funds to support regular highway maintenance, which began the next year. In 1921, the state legislature turned the Department of Engineering into the Department of Public Works, which continued to have a Division of Highways.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 32. That same year, three additional divisions (now districts) were created, in Stockton, Bishop, and San Bernardino. In 1933, the state legislature enacted an amendment to the State Highway Classification Act of 1927, which added over 6,700 miles of county roads to the state highway system. To help manage all the additional work created by this massive expansion, an eleventh district office was founded that year in San Diego. The enactment of the Collier–Burns Highway Act of 1947 after "a lengthy and bitter legislative battle" was a watershed moment in Caltrans history.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 72.

.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 73. Over the next two decades after Collier-Burns, the state "embarked on a massive highway construction program" in which nearly all of the now-extant state highway system was either constructed or upgraded. In hindsight, the period from 1940 to 1969 can be characterized as the "Golden Age" of California's state highway construction program.Raymond Forsyth and Joseph Hagwood, ''One Hundred Years of Progress'' (Sacramento: California Transportation Foundation, 1996): 74. The history of Caltrans and its predecessor agencies during the 20th century was marked by many firsts. It was one of the first agencies in the United States to paint centerlines on highways statewide; the first to build a freeway west of the Mississippi River; the first to build a four-level stack interchange; the first to develop and deploy non-reflective raised pavement markers, better known as

Maintenance and construction costs grew at twice the inflation rate in this era of high inflation; the reluctance of one governor after another to raise fuel taxes in accordance with inflation meant that California ranked dead last in the United States in per-capita transportation spending by 1983. During the 1980s and 1990s, Caltrans concentrated on "the upgrading, rehabilitation, and maintenance of the existing system," plus occasional gap closure and realignment projects.
