A full closure to automobiles and other vehicles will shorten the time to construct a trench for Bay Area Rapid Transit (BART) trains to pass under Dixon Landing Road for SCVTA's BART Silicon Berryessa Extension.
The Dixon Landing Road grade separation is one of 11 required in the BART corridor to separate BART trains from vehicle traffic and pedestrians. These separations are a key component to safe and efficient BART service. Dixon Landing Road, as well as the freight railroad will remain at their current ground level.
The eight-month closure allows for crews to work extended hours and avoid numerous traffic switches that would have to occur if limited access to vehicular traffic were provided. A partial closure would have also extended the construction schedule to 18 months instead of the accelerated eight months schedule. Dixon Landing Road is expected to reopen in early 2015.
Construction activities include relocating major utilities, excavating the roadway, installation of metal sheets for shoring, building a street level bridge for Dixon Landing Road, corridor grading and a new BART trench.
