A freeway notorious for its traffic, the 91 serves three counties in three very divergent areas. It starts out in a coastal city, passes through the coastal plain, then winds through a river canyon to head into the Inland Empire. It is that river canyon – Santa Ana Canyon, that traffic tends to slow. To help alleviate some of the backup, toll lanes were constructed in the 1990’s in the median of the freeway from the 57 to the near the Riverside County Line. These lanes have been extended to the 15 including a direct connector with the 15 South. The freeway will have HOV lanes running along most of its length, from the 110 to its eastern terminus at the 60 in Riverside.
