Interstate 110 and State Route 110 (California)
Route 110, consisting of State Route 110 (SR 110) and Interstate 110 (I-110), is a state and auxiliary Interstate Highway in the Los Angeles metropolitan area of the US state of California. The entire route connects San Pedro and the Port of Los Angeles with Downtown Los Angeles and Pasadena. The southern segment from San Pedro to I-10 in downtown Los Angeles is signed as I-110, while the northern segment to Pasadena is signed as SR 110. The entire length of I-110, as well as SR 110 south of the Four Level Interchange with US Route 101 (US 101), is the Harbor Freeway,[2] and SR 110 north from US 101 to Pasadena is the historic Arroyo Seco Parkway, the first freeway in the western United States.[3]

Harbor Transitway[edit]
The Harbor Transitway is a grade-separated, shared-use express bus and high-occupancy toll (HOT) corridor, running in the median of I-110, between SR 91 (Gardena Freeway) and Adams Boulevard in the south side of Downtown Los Angeles. Southbound buses exit the HOT lanes at dedicated ramps connecting to the Harbor Gateway Transit Center. Each vehicle using the HOT lanes is required to carry a FasTrak Flex transponder, with its switch set to indicate the number of the vehicle's occupants (1, 2, or 3 or more), regardless of whether they qualify for free.[7]
Preservation[edit]
Despite the increased traffic in Los Angeles, including trucks shipping products from the Port of Los Angeles in San Pedro, there are no plans to upgrade the rest of I-110 from I-10 to Pasadena to Interstate standards. Instead, Caltrans has pushed for a protected status alternative to preserve the Arroyo Seco Parkway as a historic landmark. The state legislature designated the original section, north of the Figueroa Street Viaduct, as a "California Historic Parkway" (part of the State Scenic Highway System reserved for freeways built before 1945) in 1993;[43] the only other highway so designated is the Cabrillo Freeway (SR 163) in San Diego. The American Society of Civil Engineers named it a National Historic Civil Engineering Landmark in 1999,[44] and it became a National Scenic Byway in 2002.[45]
