State Route 83


Leaving the California 71 (Chino Valley Freeway) interchange, California 83 proceeds north along Euclid Avenue toward Upland. The San Gabriel Mountains rise to the north. - 04/20/2013
California 83 is Euclid Avenue, originating at California 71 (Chino Valley Freeway) in southern San Bernardino County and extending north through Ontario to end at the point where Euclid Avenue crosses over California 210 (Foothill Freeway) in Upland. The state route was slightly extended north from 19th Street (old California 30) with the completion of California 210, but there is no direct connection between the two routes.

The state route begins at the Shady View Drive, just south of the California 71. Beyond ramps with California 71, California 83 proceeds almost due north toward Ontario.
