Completed, per SolTrans.
Since SolTrans' bus redesign took effect August 2, Benicia's hourly express bus no longer goes to Walnut Creek BART. The route, renamed from the Yellow Line to Route 70, keeps all its Benicia stops and now ends at the North Concord and Concord BART stations. SolTrans said in its 2025 draft plan that Vallejo and Benicia residents make about three times as many trips to the Concord area as to Walnut Creek, and that ending in Concord avoids congested stretches of I-680. No SolanoExpress route serves Walnut Creek on SolTrans' current maps. On September 1, SolTrans adjusted Route 70's schedule to add travel time to Concord BART. Benicia's local Routes 15 and 17 did not change.

Summary
SolTrans' 2025 COA draft plan describes the existing Yellow Line as connecting Vallejo, Benicia and Walnut Creek BART, and proposes shifting it to Concord and North Concord BART with no change to Vallejo or Benicia routing and the same 60-minute frequency. It cites about 3x more trips by Vallejo and Benicia residents to the Concord area than to Walnut Creek, and I-680 congestion.
