California State Route 110 South
Back in 2003, we took a walk on the Arroyo Seco Parkway courtesy of ArroyoFest, a onetime festival in honor of the Arroyo Seco. We began the walk at the north end of the Pasadena Freeway (historic Arroyo Seco Parkway) southwest through the arroyo, ending at Avenue 43 (Exit 27). SR 110 leaves the city of Pasadena and enters the city of South Pasadena (population 24,292 as of 2000 Census and incorporated on March 2, 1888).

The ArroyoFest was held on June 15, 2003, as an opportunity to walk along an historic parkway that is normally a very busy and congested freeway. Organizers hoped to host additional freeway walks in the future to continue to foster community relations.

The Arroyo Seco Parkway (Pasadena Freeway) begins as Arroyo Parkway transitions directly onto southbound SR 110 as it leaves the city of Pasadena. The segment of Arroyo Seco Parkway was designated as U.S. 66 from the parkway's construction in 1940 until 1964, when that route was decommissioned.

Two lanes carry the Pasadena Freeway (Arroyo Seco Parkway) south through South Pasadena leading into Los Angeles. Note the overall narrowness of the road and right of way and the limited sight distance. This highway is listed in the National Historic Registry, and it is not likely to be reconstructed into a modern freeway.

SR 110 crosses the Arroyo Seco at this bridge. It was built in 1939 ... yes, a bridge that old is still in use along this major freeway. Note the presence of a sidewalk, which may harken back to a day when sidewalks may have been considered for use on freeway bridges.
