As they enter South Pasadena, northbound motorists can see a "City of South Pasadena" sign constructed, in the late 1930s, of stones from the creek bed embedded in a hillside. This final segment of the Arroyo Seco Parkway heads east in a cut alongside Grevelia Street, with a full diamond at Orange Grove Avenue and a half diamond at Fair Oaks Avenue. In between those two streets it crosses under the L Line for the third and final time. Beyond Fair Oaks Avenue, SR 110 curves north around the east side of Raymond Hill and enters Pasadena, where the final ramp, a southbound exit, connects to State Street for access to Fair Oaks Avenue. The freeway, and state maintenance, ends at the intersection with Glenarm Street, but the six- and four-lane Arroyo Parkway, now maintained by the city of Pasadena, continues north as a surface road to Colorado Boulevard (historic U.S. Route 66) and beyond to Holly Street near the Memorial Park L Line station.
