This route remains as defined in 1963.
This was LRN 81, defined in 1933.
According to research done by Tom Fearer, LRN 81 was an adoption of the
already existing North Bank Road. North Bank Road can be seen on the
1917 California State Automobile Association Map of California. It is
first shown as LRN 81 on the 1935 Division of Highways Map of Del Norte

Sign Route 197 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 197
between 1934 and 1964. Sign Route 197 first appears on a state highway map
in 1964, and appears to have been first signed in 1969*.

Truck Passing Improvements (DN 3.2 to DN 4.5)
In December 2012, the CTC reviewed a draft EIR related to improvements on Route 197 and US 199 and had no comments. The project will improve spot locations on Route 197 and US 199 in Del Norte County so that two Surface Transportation Assistance Act (STAA) trucks passing in opposite directions can be accommodated. Within the project limits, Route 197 and US 199 are rugged, two-lane conventional highways with tight curves and steep-cut slopes providing narrow traffic lanes with narrow shoulders (if shoulders exist). Route 197 is the designated route for the movement of extralegal truck loads between US 101 and US 199 because it avoids traversing Jedediah Smith Redwoods Park. Known as North Bank Road, Route 197 was built in the 1930s. US 199 in the project limits traverses the Middle Fork Smith River and was built in the early 1920s and is a tightly curved alignment with spectacular views. The proposed work consists of roadway widening, shoulder widening, roadway curve improvements, bridge replacements and culvert replacements. The project will bring Route 197 and US 199 into compliance with federal and state legislations regarding access for STAA trucks. It is split into four projects: Ruby 1 (EA 48110, Route 197 PM 4.5) is fully funded in the SHOPP Minor A Program. It would lengthen the curve and increase shoulder width. Culverts and drainage would be adjusted. The total estimated cost is $2,499,000. Construction is estimated to begin in Fiscal Year 2013-14. Ruby 2 (EA 45490, Route 197, PM 3.2 to 4.0) is fully funded in the SHOPP Minor A Program. This would improve the existing road curve, roadbed elevation, and roadway width. Different alternatives have slightly different roadway and shoulder widths. The total estimated cost is $3,400,000. Construction is estimated to begin in Fiscal Year 2014-15. Patrick Creek Narrows (PPNO 1047) will improve US 199 from Post Mile 20.5 to 20.7, Post Mile 23.9 to 24.3, and Post Mile 25.55 to 25.65. Most of these involve improving curves and slight roadway widening. It would also replace the existing Middle Fork Smith River bridge with either an upstream or downstream alternative, or rework the existing bridge to allow large trucks to cross. The project is programmed in the 2012 STIP. The total estimated cost for capital and support is $21,302,000. Construction is estimated to begin in Fiscal Year 2012-13. The Narrows and Washington Curve (PPNO 1073) will improve US 199 from Post Mile 22.7 to 23.0 (Narrows), and from PM 26.3 to 26.5 (Washington Curve). These involve lane widening and curve improvement. The project is programmed in the 2012 SHOPP. The total estimated cost for capital and support is $6,750,000. Construction is estimated to begin in Fiscal Year 2015-16. For these four projects, there are a total 12 build alternatives being proposed as well as the no build alternative
In June 2013, the CTC accepted the environmental document for Ruby 1, Ruby 2, Patrick Creek Narrows, and Narrows and Washington Curve.

Overall statistics for Route 197:
In 1933, Chapter 767 defined the route from "[LRN 77] near Escondido to El Cajon-Santa Ysabel Road near Ramona" as part of the state highway system. In 1935, this route was added to the highway code as LRN 197 with the routing:
