The I-680 Transit Investment and Congestion Relief Options Study was initiated in April 2015 and finalized in December 2015. The primary purpose of the Study was to define and evaluate potential transportation investment options that could reduce traffic congestion and encourage transit ridership on the I-680 corridor in the general area from the Benicia-Martinez Bridge to State Route-84 with a focus on potential transit service improvement options between Walnut Creek and Dublin.
The study evaluated five possible options, including:
Following an evaluation of each option, the study identified the most feasible and financially viable project as a combination of enhanced express and local bus service, connected vehicle and automated vehicle support in the corridor, and active traffic management. This includes new park and ride lots in the corridor, known as Smart Mobility Hubs, and use of the shoulders of I-680 for bus operations. Links to the executive summary and full study are found below.
