California State Route 189

This past month I drove California State Route 189 in the San Bernardino Mountains.  CA 189 has the distinction of being of the few State Routes in California which is currently signed with the same number as it's Pre-1964 Renumbering Legislative Route Number.


CA 189 is a 6 mile State Highway entirely located within San Bernardino County.  CA 189 connects CA 18 on the crest of the San Bernardino Mountains to CA 173 in Lake Arrowhead.



Part 1; the History of California State Route 189

The history of California State Route 189 begins in 1933 when Legislative Route 189 was adopted into the State Highway System.  LRN 189 was not one of original run of Sign State Routes and mostly served as an alternate to Lake Arrowhead over CA 18/CA 2.  The route of LRN 189 appears on the 1935 Division of Highways Map of San Bernardino County.


As noted above LRN 189 was assigned CA 189 during the 1964 State Highway Renumbering.  CA 189 shares a distinction with CA 58 and CA 127 of being highways that have a current route number that matches their Pre-1964 Legislative Route Number.  In the case of CA 127 it is the only route that had a Legislative Route Number which matched it's field signage before 1964.  CA 189 is too small to pick up graphically on the 1964 Division of Highways Map but is referenced in the list of State Highways.



Part 2; scenery along CA 189

From CA 18 eastbound junction of CA 189 is located at Lake Gregory Drive.  Interestingly the junction of CA 189 isn't signage from CA 18.  There isn't really any indication from CA 18 eastbound that there is an alternate route from Lake Arrowhead.




From CA 173 northbound at Lake Arrowhead Village the junction of CA 189 on Lake Edge Road also isn't signed.  In the two photos below CA 173 north meets CA 189/Lake Edge Road on the left hand side.



That said, CA 189 on the actual highway is very well signed.  CA 189 westbound on Lake Edge Road has an immediate reassurance shield.


CA 189 also has end route signage at both terminus points.  CA 189 even has junction signage at it's eastern terminus with CA 173 but lacks it for CA 18 at the western terminus.

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Old River Lock & Control Structure (Lettsworth, LA)

  The Old River Control Structure (ORCS) and its connecting satellite facilities combine to form one of the most impressive flood control complexes in North America. Located along the west bank of the Mississippi River near the confluence with the Red River and Atchafalaya River nearby, this structure system was fundamentally made possible by the Flood Control Act of 1928 that was passed by the United States Congress in the aftermath of the Great Mississippi River Flood of 1927 however a second, less obvious motivation influenced the construction here. The Mississippi River’s channel has gradually elongated and meandered in the area over the centuries, creating new oxbows and sandbars that made navigation of the river challenging and time-consuming through the steamboat era of the 1800s. This treacherous area of the river known as “Turnbull’s Bend” was where the mouth of the Red River was located that the upriver end of the bend and the Atchafalaya River, then effectively an outflow

Huey P. Long Bridge (Baton Rouge, LA)

The decade of the 1930s brought unprecedented growth and development to Louisiana’s transportation infrastructure as the cities of New Orleans and Baton Rouge cemented their place as leading urban centers on the Gulf Coast. In the immediate aftermath of the success garnered by the construction of the massive bridge on the Mississippi River near New Orleans in 1935, planning and construction commenced on the state’s second bridge over the great river. This new bridge, located on the north side of Baton Rouge, was to be similar in design and form to its downriver predecessor. Completed in 1940 as the second bridge across the Mississippi River in Louisiana and the first to be built in the Baton Rouge area, this bridge is one of two bridges on the Mississippi named for Huey P. Long, a Louisiana politician who served as the 40th Governor of the State from 1928 to 1932, then as U.S. Senator from 1932 until his death by assassination at the state capitol in Baton Rouge on September 10, 1935
