State Route 188 (SR 188) is a two-mile (3 km) route that connects State Route 94 with the Mexico – United States border. Its southern terminus is at the border near Tecate, Baja California and its northern terminus is near Tecate, California with SR 94. The route was assigned in the area in 1972, and has remained intact since.
State Route 188 or Tecate Road begins at the U.S.-Mexico border in the community of Tecate, Baja California; this border crossing handled roughly four percent of all traffic in between Baja California and California during 2008. The route progresses northward, passing through a large commercial district in Tecate, California. The highway heads to an intersection with Thing Road, where it turns to the northeast and out of the commercial district. The route continues to the northeast, intersecting with Humphries Road, where the surroundings become highly undeveloped. SR 188 continues to an intersection with SR 94 a short distance out of Potrero, where the designation ends and right-of-way merges into SR 94.
The entire route is in the National Highway System, a network of roadways important to the country's economy, defense, and mobility. In 2013, SR 188 had an annual average daily traffic (AADT) of 5,600 at the northern terminus, and 5,900 at the southern terminus, the latter of which was the highest AADT for the highway.
