*Due to existing requirements, work taking place directly over or adjacent to BART and Union Pacific Railroad operations will be performed at night and/or on weekends when the trains are not in operation. Regular weekday night hours – when this type of work can take place – are from 1:30 a.m. – 3:00 a.m. Weekend night hours for this type of work are from 1:00 a.m. – 7:00 a.m. Advance notice of night, weekend and/or noisy work activities will be provided to the local community when the work is scheduled.

The majority of project construction is anticipated to take place during regular weekday hours, from 7:30 a.m. to 4:00 p.m. However, there may be instances where weekday construction hours are extended from 7:00 a.m. to 7:00 p.m. in order to expedite or complete ongoing work. Saturday work hours are from 9:00 a.m. – 5:00 p.m. (if needed). Some work may extend into Sunday to complete ongoing work, or to make up for any delays caused by adverse weather.

All construction dates and times are subject to change due to weather and unforeseen conditions, and/or the availability of on-site Union Pacific Railroad flaggers and BART safety monitors.

Bridge Construction Continues

The new bridge is being constructed immediately south of the existing bridge. Construction is anticipated to be complete spring 2017.

  • No weekend work is expected for the weekends of August 12-13, 19-20, or 26-27.
  • The Stage 2 traffic shifts, which redirect eastbound traffic onto the new bridge, began August 2nd. Westbound traffic temporarily remains on the old bridge. This 2nd Stage shift will continue until the last week of August.
  • The Stage 3 temporary realignment of traffic is anticipated for late August while the existing bridge and approaches are demolished. This 3rd Stage alignment will continue until late September and will allow eastbound and westbound traffic onto the new bridge.
  • The eastbound movement on the left turn from Niles Boulevard to Linda Drive and the left turn onto Niles Boulevard from Linda Drive will be closed during Stages 2 and 3 until the first week of October. A detour using El Portal Avenue is in place.
  • Once construction activities between the bridges have been concluded in mid-October, traffic will be placed in its final alignment on the new bridge and permanent striping and signage will be installed.
  • Bridge demolition is scheduled to start Thursday August 24th. This work will take place during the day, from 7:00AM-4:30PM, until Friday, September 1st.
  • Night-time/early morning work will begin on Saturday September 2nd, from 12:30AM-10:30PM, and will continue 7 days a week until the bridge is completely demolished. The anticipated completion date for this period of night-time work is September 17th.  This work will be noisy, but not as much as the aisle-driving early on in the project.  We are limited to operate in these hours due to restrictions to activities over railroad tracks set in place by BART and UPRR.
  • Community members may hear train horns near the project site during regular construction hours. Train operators are required to sound a warning as they pass through a known construction zone.

PLEASE NOTE: The work activities and dates listed above are subject to change due to weather, unforeseen conditions, and/or the availability of on-site Union Pacific Railroad flaggers and BART safety monitors.
