Today, Sept. 11, the Seattle Department of Transportation will be closing hte outside, northbound lane once again as they continue work on upgrading the lighting system on the bridge. The closure will take place from 9 a.m. to 2:30 p.m.

Tomorrow, Wednesday, they will switch sides and close the outside southbound lane from 9 a.m. to 2:30 p.m.

What're they doing, you ask? Crews will be taking out four light poles so that new pole bases can be installed.

Sidewalks will stay open. SDOT says the schedule for the rest of the week will be determined once the poles are removed. Remember that significant delays could be caused if the bridge goes up.
