Recently while descending Cajon Pass I drove a small portion of Interstate 215 from the I-15 split in California State Route 210 in San Bernardino.
I-215 is a 54 mile loop of I-15 beginning near Cajon Pass in San Bernardino County and ending to the south in Murrieta of Riverside County. I-215 essentially serves as a limited access replacement of US 66/91/395 on Legislative Route Number 31 south towards I-10. South of I-10 the route of I-215 follows what was US 91/395 on LRN 43 to US 60/LRN 19. I-215 shares a brief multiplex of CA 60 near Riverside and what was US 60/395 on LRN 19 to what was US 395/LRN 78 towards Murrieta.
According to CAhighways.org I-215 was first approved as a Non-Chargeable Interstate south to I-10 as I-215 in 1972. The route designation was swapped to I-15 East by 1973 with an additional portions of Non-Chargeable roadway added south to CA 60. By 1982 the designation of I-15 East was reverted back to I-215.

The 1975 State Highway Map shows I-15E co-signed with US 395 (I guess that kicks the whole date of truncation to Hesperia even further into the 1970s) from Cajon Pass towards Sunnymead in modern day Moreno Valley.

Of note, the map above shows the unsigned CA 194 aligned over all of what would become I-15E. The designation of CA 194 (which was the second time this number was designated) was defined in 1974 and used as a hidden route number since suffixed highways are not allowed legislatively in California. The hidden CA 194 designation of I-15E would disappear when the route was reverted back to I-215 in 1982.

The 1977 State Highway Map shows US 395 removed completely from I-15E/CA 194. I-15E appears to have been completed signed on it's entire route by 1977 but clearly was using some temporary alignments south of Sun City (modern Menifee). According to CAhighways.org I-215 wouldn't be completed to modern Interstate standards until 1996.

I-15E can be seen changed to I-215 by the 1986 State Highway Map, the 1982 Edition still shows the previous designation. Of interest the non-Interstate standard portions of 215 south of CA 60 are shown as CA 215 on the 1986 map.

As stated above my approach to I-215 south was from I-15 south descending from Cajon Pass.
I-215 south quickly enters San Bernardino and closely follows from US 66/91/395 east of Cajon Boulevard.
On I-215 south approaching CA 210 traffic headed to CA 18 and CA 330 are directed to exit eastbound.
As I-215 south approaches the interchange with CA 210 there are three exits. CA 210 East traffic is directed onto Exit 46C whereas westbound traffic is directed to Exit 46A. Traffic headed to Mount Vernon Avenue and 27th Street is directed to take Exit 46B.
Interestingly CA 66 is now signed from I-215 south approaching 5th Street. I turned off I-215 south at Base Line Street to take CA 259, once I return to this highway I will extend the photo log.
