Seattle City Light crews plan to enhance the reliability of the electrical system by pulling in new fiber-optic cables across Interstate 405 approximately two miles southeast of Alderwood Mall. To ensure safe work operations and passage for motorists, crews must intermittently conduct rolling slowdowns of traffic in both directions of I-405.
The work will take place at night beginning Monday, Sept. 18. Traffic will be intercepted and escorted at slow speeds for up to 15 minutes between just southeast of the I-5/I-405 interchange and NE 195th Street as crews install the new fiber-optic cable overhead across the highway. Traffic will return to normal speeds once past the work area. See the map below for details on the differing locations for north and southbound rolling slowdowns. Drivers should expect delays and consider using alternate routes during construction.
Rolling slowdown details:
Occurring nightly from 11:59 p.m. to 4 a.m. beginning Monday, Sept. 18 through the morning of Friday, Sept. 22:
- Washington State Patrol troopers and contracted crews will intermittently intercept and escort southbound I-405 traffic through the work area beginning southeast of the I-5/I-405 interchange. The same will occur for northbound traffic beginning at NE 195th
- Traffic using the following on-ramps to I-405 will also be affected: I-5 northbound to I-405 southbound, I-5 southbound to I-405 southbound, NE 195th Street to northbound I-405, State Route 527 northbound to northbound I-405, and State Route 522 to northbound I-405.
- Should the crews finish in less than four nights, City Light plans to communicate via social media and at this Website: http://www.seattle.gov/light/atwork/release.asp?RN=397
Customers will benefit from increased electrical reliability. The new fiber-optic lines will provide redundant communication between facilities generating power at City Light’s Skagit hydropower sites, the Bonneville Power Administration, and City Light substations and its system control center.

Map showing affected area of northbound and southbound rolling slowdowns on I-405
Seattle City Light crews are planning emergency repair work to restring electrical wires pulled down across Interstate 5 by last Saturday’s car/pole collision at NE 125th Street. The work will impact traffic on Interstate 5. Drivers should expect delays and consider using alternate routes.
To complete the work safely, crews must intermittently stop traffic in both directions of I-5 overnight for up to three nights. Traffic may be stopped up to 25 minutes at a time between State Route 520 and NE 205th Street as crews pull power lines across the highway.
Rolling slowdown details:
- Work will be performed Tuesday, April 25, through the morning of Friday, April 28.
- Crews will intermittently stop traffic on I-5 between SR 520 and NE 205h Street from 11:59 p.m. to 4 a.m.
- Washington State Patrol troopers will assist with traffic control and escort drivers through the construction zone.
If you have questions/concerns during normal work hours, City Light’s point of contact is Mark VanOss, Sr. Public Relations Specialist, at (206) 684-3279 or firstname.lastname@example.org. If your question is urgent, leave a message at (206) 386-4233 and you will be contacted.
Seattle City Light plans to inspect streetlights on the Ballard Bridge following the Seattle Department of Transportation’s seismic upgrades. The inspection is scheduled for Thursday, Dec. 17 starting at 7 p.m. and ending at 6 a.m. on Friday, Dec. 18. The location of the inspection can be found here: BallardBridgeMap
Single northbound and southbound lane closures on the bridge will be necessary. Motorists should expect rolling slowdowns in the direction of the affected lane. Only one lane at a time will be closed. Work will start in the southbound lane and end with the northbound lane. One quarter of the streetlights on the bridge will be out at a time. Spotters will assist any pedestrians and cyclists.
Inspection of the streetlight system is needed to close the construction contract and transfer ownership of the lights to Seattle City Light. Customers can contact: Tom Borek, Streetlight Engineer, (206) 684-4920, email@example.com.

Fiber Optic Upgrade Project Will Cause Rolling Slowdowns Near Boeing Field; Alternate Routes Encouraged
City Light will be enhancing electrical system reliability by upgrading the communication link between two south end substations and the utility’s system control center. The work requires pulling fiber optic communications cable across State Route 99 (SR 99) near Boeing Field. The work is being done in coordination with Washington State Department of Transportation (WSDOT) and City Light’s H-Frame/Feeder installation project currently underway in the same area.
The project is planned for October 11, 2014, from 6 a.m. to 11 a.m. Rolling slowdowns on SR 99 and traffic escorts through the construction zone for this project are necessary for motorist and worker safety. There will be up to six 15-minute rolling slowdowns during the five-hour period. Drivers are advised to carefully abide by traffic restrictions and consider using alternate routes during construction. Normal traffic flow will follow once the project is complete.
Beyond enhancing communication capabilities by keeping the system control center in touch with substations, the new fiber optics are required to monitor lights on newly placed towers near I-5.
