SR 185 SR 187

State Route 186 (SR 186) is a route that connects Interstate 8 with the U.S.-Mexico border near the Colorado River. Its southern terminus is near Los Algodones, Baja California, and its northern terminus is near Winterhaven, California in the location of Araz Junction. The route is only 2.070 miles (3.331 km) long, heading along the length of the Alamo Canal and the All-American Canal within the boundaries of the Fort Alamo-Quechan Reservation. The route was assigned in 1972 in Imperial County and the interchange with Interstate 8 was constructed a year later.

Route description

State Route 186 begins at the United States/Mexico border (near Avenue International) in the community of Los Algodones. The route heads to the northeast along the Alamo Canal and crosses the center of the Fort Alamo-Quechan Reservation. Most of the surroundings of SR 186 are desolate, compared to the highway's continuation in Mexico, which is populated and developed. The highway continues northward, crossing the All-American Canal, where it turns to the north. State Route 186 continues northward to an interchange with Interstate 8 in Araz Junction, where the route terminates at the northbound ramps. The route continues northward as a locally-maintained Araz Road.[2]

History

The current alignment of State Route 186 was assigned in the area of 1972, when Chapter 742 was passed by the California State Legislature.[3] The route has remained unchanged since.[4] There are two bridges along the alignment of SR 186. The first one to be constructed was a concrete slab bridge over the All-American Canal, with the structure opening in 1938. The bridge is 140.09 feet (42.70 m) long, and is basically unable to sustain the traffic it was designed to handle.[5] The second bridge is located at the interchange with Interstate 8 in Araz Junction. This bridge, constructed in 1973 (a year after the route was assigned), is a 227.03-foot (69.20 m) long concrete box beam structure. This structure, unlike the other is recorded to be in usable shape.[6]
