TC 21-11 Item 9a Study Area Map.png



The San Gabriel Valley has over two million residents and covers more than 374 square miles. Bordered by Los Angeles to the west, San Bernardino County to the east, the San Gabriel Mountains to the north and the hills south of State Route (SR) 60 to the south, this diverse and expansive area includes densely populated cities, employment centers, and residential areas.


For the purposes of this project, there are two different focus areas within the Study Area Boundary. The Focus Area for Integration of Services will leverage existing assets such as the Metro L Line (Gold) to integrate with connecting services. The Focus Area for New Services targets areas that may be currently underserved and lacking in high-quality frequent transit service. The Focus Area for New Services includes the I-10 and SR-60 corridors, which both serve as vital east/east corridors through the San Gabriel Valley.


The Transit Feasibility Study includes two phases of work. Phase 1 of the Study commenced in July 2021 and was completed in September 2022.​ In October, we moved into Phase 2, which is expected to be completed in December 2023.

Following initial screening during Phase 1, which included consideration of stakeholder input on the 15 alternatives, seven alternatives were advanced for further study, two east-west alternatives and four north-south alternatives. During Phase 2, the alternatives were narrowed down to five, with a Hybrid East-West Alternative and four North-South Alternatives. The alternatives continue to be studied to advance the more feasible ones for near-term implementation of bus lanes to support new BRT service upon receipt of more in-depth analysis and stakeholder input. All promising alternatives, regardless of their recommendation for near-term BRT implementation, are included in the Vision Plan as Bus Priority Corridors where rapidbus-type improvements, including transit priority and more frequent service, could be provided. The Vision Plan segments not selected for short-term implementation could be considered for long-term implementation in future years.

The purpose of this Study is to identify feasible transit solutions that enhance communities and lives by providing a high-quality mobility project in the San Gabriel Valley. Following are the technical criteria for evaluating the various alternatives:
