Most of you from around San Bernardino know the story of how the McDonald brothers moved to California from New England to California, where they tried running a drive-in restaurant in Arcadia. They moved to San Bernardino, where they thought it would be better, but it was no different.
The books (and the brothers) always said something about both establishments being on US 66.
Those of us who grew up after the freeway was built (originally I-15, then I-15E, now I-215) remember that Business Route US 66 (the old highway) joined Business Route US 395 at the corner of Fifth Street and Mount Vernon Avenue. Past Highland Avenue, the route moved to Cajon Boulevard where it left San Bernardino.
But there was also a City Route, which was discontinued when the freeway was built: At the intersection of Fifth Street and Mount Vernon Avenue, City Route 66 continued eastward to E Street. At E Street it went north until it hit Kendall Drive, which almost paralleled Cajon Boulevard, but at the end, when Kendall met Cajon, that was where the City Route ended. That was until 1964.
And it was on this road that the original McDonald's was located.
From 1964 to 1982, the section of this route from Highland Avenue to the Interstate was marked as California State Route 206, which didn't include the former McDonald's site.
Now, if you can find an old Riverside-San Bernardino Street Map, which you probably got for free at a Signal Gas Station in 1961, you can see what I mean.
