“The Benicia-Martinez Railroad Drawbridge, a lofty Bay Area landmark for 95 years, has developed an altitude problem. The structure is too low for the speedier, more frequent trains that the Capitol Corridor intends to run in the future as part of its ambitious plan to boost rail between the Bay Area and Sacramento. The regional passenger service says the solution is to build a new, higher bridge either next to the current one or several miles west, between Crockett and Vallejo. Those plans are underway as the current structure awaits its fate. The problem is due to maritime traffic. The drawbridge’s vertical lift span rises several times a day to allow large ships to pass underneath. The lifts halt rail traffic for 20 minutes or more, according to a consultant’s report for the Capitol Corridor Joint Powers Authority, and ‘represent the second most significant cause of delays to [corridor] trains.'” (06/10/25)
