State Route 30, Part 5.
Stubs from the Fontana city limit to Alder Ave.
On our final trek (for now) we travel the remaining parts of Highland Ave through Fontana, up to Alder Ave. There, we turn around for now, as past that most of the remaining road has been replaced by SR 210. At Locust Ave in Rialto, So Highland Ave becomes Easton St. Past Riverside Ave, the remaining road curves north over SR 210 and becomes Highland Ave again, just west of San Bernardino city limits. Highland Ave carries BR 30, still technically signed (although California has a terrible track record of doing so) and is the former alignment of SR 30 itself before it was moved the the freeway. In the city of Highland, we meet the junction of SR 30's two pre-freeway alignments: the earlier City Creek Rd alignment through the San Bernardino National Forest to SR 18 in Running Springs (now SR 330, SR 30's only spur route). The 1970's deletion of SR 106 saw it's route transferred to SR 30, and SR 30's former City Creek Rd alignment was transferred to SR 330. Boulder Ave/SR 30 from Highland Ave to Greenspot Rd (former 106) was later upgraded to a divided expressway. Just beyond that, Boulder Ave becomes Orange St as it enters Redlands. SR 106's southern terminus was at Lugonia Ave/SR 38, but when it was transferred to SR 30 the route was extended a block south, thus moving it's eastern terminus to I-10.
Detour: SR 210 E via Beech Ave Carpool/HOV entrance.
Since we had to backtrack to Knox, we might as well backtrack all the way to Beech Ave and hop on the freeway. Better have two people in the car for this one, this is a Carpool (or now that California has embraced the standard term, HOV) Only entrance. The center/right merge made sense here, since brand new homes were already built on both sides of the freeway.
Bypassing the stub between Citrus and Sierra that's be primarily repurposed for two new auto dealerships, we exit the freeway at Sierra Ave and head south to the next intersection with So Highland Ave and turn left (east). We start a bit south of the original alignment but level out shortly.
