| Interstate 15 (Ontario Freeway) south |
|
Southbound Interstate 15 (Ontario Freeway) approaches its interchange with California 60 (Pomona Freeway) once it enters Riverside County. The east-west freeway heads west to Pomona and Los Angeles and east to Riverside and Moreno Valley. Riverside County is also considered to be part of the Inland Empire, which is generally considered to be all the communities within the basin from San Bernardino in the north to Corona in the south and west to Chino Hills/Pomona and east to Moreno Valley. Some describe the Inland Empire as containing more or all of San Bernardino and Riverside Counties, but it is generally a term mostly applied to this populated valley. Photos taken 07/26/09 and 06/27/04. |

A rare double-circuit 500kV power line crosses over Interstate 15 at the California 60 interchange; this line is also part of Path 46. Photo taken 09/28/08. |
|
|
Now on the connecting ramp from Interstate 15 south to California 60, the left lane travels east to Riverside, while the right two lanes lead west to Los Angeles. The second photo follows the flyover ramp to California 60 east. Photos taken 09/28/08. |
|
The last section of Interstate 15 to be completed in Riverside County was generally between California 60 and California 91. Once constructed in the 1980s as a six-lane freeway, it has not been upgraded since then. Traffic delays such as this congestion during commuting hours, have escalated on Interstate 15 as more cars and trucks use the freeway. Photo taken 03/25/05. |
|
|
Passing under California 60, the highest ramps fly over the top of Interstate 15. Photos taken 07/26/09 and 03/25/05. |
|

|
Southbound Interstate 15 reaches Exit 103, Limonite Avenue. The section of Interstate 15 (Ontario Freeway) between California 60 and California 91 was constructed in the mid-1980s and features a different design standard than the section north of California 60 and south of California 91. One of these features is the smaller sign bridges, such as this one found along southbound at Exit 103, Limonite Avenue. Limonite Avenue heads east to Pedley and Rubidoux (ending at California 60 Business (Mission Boulevard) just west of Riverside), roughly following the Santa Ana River. Photo taken 07/26/09. |

|
Southbound Interstate 15 reaches Exit 100, Business Loop I-15 south/Sixth Street. There is space on this overhead sign to fit a business loop shield, but it is doubtful any such shield was ever intended to be mounted on this sign. The business loop heads west on Sixth Avenue to Hamner Avenue, then follows former California 31/Hamner Avenue through Norco south to Second Avenue. Business Loop I-15 then turns east on Second Avenue to rejoin Interstate 15. Photo taken 03/25/05. |

|
The single exit only lane widens into two lanes as southbound Interstate 15 approaches California 91. Signed east-west, most of California 91 follows the original alignment of U.S. 91 roughly between Interstate 5 and California 60/Interstate 215. U.S. 91 was decommissioned along with many other California U.S. routes in 1964; signs were removed shortly thereafter. Photo taken 06/27/04. |
