Clements authorized significant road building projects. During his administration, the state funded or built 3,800 miles of rural roads and 4,000 miles of primary roads. Further, he initiated construction of the Kentucky Turnpike and the Western Kentucky Parkway. The state also assumed maintenance of 6,000 miles of county roads under Clements. During Clements' tenure, only Texas spent more money on developing its roads. Besides improving the roadways themselves, Clements replaced the Kentucky Highway Patrol, which had become a corrupt vehicle of political patronage, with the Kentucky State Police. Clements also used some of the revenue generated from his tax increases to raise the salaries of the state's public school teachers. He approved a 15% increase in funding to the Minimum Foundation Program which provided funding for poor school districts. This was not enough, however, to stave off a 1950 protest march on his office by teachers demanding that he raise another $10 million for education. Clements' lieutenant governor and successor, Lawrence Wetherby, was able to meet this demand in 1951 by using increased tax revenue resulting from the Korean War.
