Post-1964 Legistlative Route Graphic In 1963, Route 188 was defined as "the south end of Fallen Leaf Lake to Route 89 near Camp Richardson." This was Fallen Leaf Road near Lake Tahoe. Few realized it was even in the state highway system. In 1965, Chapter 1372 deleted this routing.

At the time of deletion, Route 188 was described a 4.7-mile State Highway which was unimproved single lane highway that was lightly traveled.

The 1964-1965 routing for this route was LRN 94, defined in 1933.

LRN 94 corresponded to Fallen Leaf Lake Road, which took visitors to the Fallen Leaf Lodge. It did not receive a sign route designation. LRN 94 appeared be in the State Highway system primarily due to the fact that off-grid political meetings were often held during the winter at Fallen Leaf Lake.

The 1972 routing for Route 188 was not defined in 1963.

Signed Route 188 was not defined as part of the initial state signage of routes in 1934. It is unclear what (if any) route was signed as Route 188 between 1934 and 1964.
