System Reliability Work on Spokane Street Viaduct to Start on July 14

Seattle City Light crews plan to improve electrical system reliability by pulling new wire over the top of the Spokane Street Viaduct near 2nd Avenue South.

To work safely, traffic will be reduced to one lane and the speed limit dropped to 25 mph in both the east and west bound directions of the Spokane Street Viaduct between 1st Avenue South and 6th Avenue South. See the work zone map below. Work will occur on Friday, July, 14 and Saturday, July, 15 if necessary.

Drivers should expect slowdowns during this time.
