Cable installation to interrupt light-rail service on Blue Line

Light-rail service on the northeast portion of Regional Transit's Blue Line will be temporarily suspended Saturday to allow installation of fiber-optic cable for communication upgrades.

From 1:30 a.m. Saturday until 4:15 a.m. Sunday, light-rail trains will not operate between the Marconi/Arcade and the 10th and K light-rail stations. Buses will transport passengers between the stations, according to an RT news release.

Regional Transit’s contractor will complete the connection of fiber-optic cable between stations. The cable is used for telephone, high-speed communications such as RT’s digital message signs, camera surveillance and the future Connect Card. Although the work involves only two light-rail stations – Globe and Alkali Flat/La Valentina – a larger section of the Blue Line must be shut down because of the locations of power substations, officials said.

During the work, RT’s overhead contact system will be deactivated, giving RT facilities staff an opportunity to perform maintenance work on the American River Bridge, the 12th Street underpass and other areas along the right of way.

For details on shuttle bus service, see RT’s website, sacrt.com, or look for A-frame signs at stations.
