From Route 89 at Tahoe City along the northern boundary of Lake Tahoe to the Nevada state line at Crystal Bay.

The current definition of Route 28 is unchanged from the 1963 definition.

The present-day routing of Route 28 is not the original routing. In 1934, Route 28 was signed along the route from Jct. Route 1 near Albion to Jct. US 40 near Davis, vis Sage Canyon. This corresponded to the following routes:

1. From Route 1, 8 mi S of Mendocino through Navarro, Boonville, Yorkville, and McDonald to Route 101 near Cloverdale. This was later signed as Route 128, and was LRN 48.
2. From Route 101 near Geyserville to Calistoga. This was later signed as Route 128, and was LRN 103.
3. Concurrant with Route 29 from Calistoga to 7 mi S of Napa. This was later resigned to be cosigned Route 128/Route 29, and was LRN 49. Between Rutherford and Napa, this is now signed as Route 121/Route 29.
4. From 7 mi S of Napa to Cordelia Suisun. This was signed as Route 12, and was LRN 8.
5. Concurrant with US 40 to Vacaville.
6. N from Vacaville through Winters to US99 near Woodland. This is the route of the present-day I-505, and was LRN 90.

In 1952, the original routing for Route 28 was renumbered as Route 128.

The present routing was LRN 39 (defined in 1915), and has been signed as Route 28 since 1952. Prior to 1952, the route was unsigned. The Route 28 designation permitted the route along the north shore of Lake Tahoe between Tahoe City and the California-Nevada boundary to join Nevada Sign Route 28 at the state line.

This route continues into Nevada as Nevada 28.

The route that would become LRN 28 was first defined in the 1909 First Bond Act as running from Redding to Alturas. It was also part of the "Lassen State Highway" established in 1911 by Chapter 498 as follows:

"That certain highway known as the county road and beginning on the boundary line between Shasta and Lassen Counties in the NE corner of T37N R6E and running and extending through T38N R6E, T38N R7E, T38N R8E, to the Modoc County Line...shall be designated and known as the Lassen State Highway"

It was seemingly extended in 1915 when Chapter 765 authorized the survey, location, and construction of a route "from Surprise valley, in Modoc county, to the Nevada state line." However, this authorization was rescinded in the 1935 act that created the state highway code.

In 1921, it was more directly extended with Chapter 888, which provided an appropriation “...for the survey, plans and estimates and for the construction of the highway from the town of Alturas in Modoc county to the Nevada-California state line by the most direct and practical route via Cedarville in connecting with the proposed Nevada state highway...”

By 1935, the route had been codified into the highway code as running "from Redding to the Nevada line via Alturas and Cedarville". It was primary state highway from Redding to Alturus. The 1935 definition remained unchanged until the great renumbering in 1963. The entire route was signed as US 299 between Redding and US 395. The signate E of US 395 to the Nevada border before 1964 was unclear.
