WHAT THEY WANT

(Summarized from the RFP)

The City of South Pasadena is seeking a qualified consultant to carry out a planning-level comparative evaluation of two concepts for improving the Fair Oaks Avenue and Arroyo Parkway (SR-110) interchange: a Hook-Ramp Alternative and a Loop-Ramp Alternative. The interchange has longstanding operational problems, including parkway-era geometry, substandard ramp spacing, merge and weave conditions, conflicts between freeway access and local circulation, and regional traffic diversion tied to the incomplete SR-710 corridor.
