Seattle - SR 520 Bridge Closure 6.19 - 6.22
Annual inspection closes SR 520 Evergreen Point floating bridge this weekend
Date: Tuesday, June 16, 2009
SEATTLE ‘«Ű WSDOT maintenance crews will close the SR 520 floating bridge for annual weekend inspection and maintenance work Friday, June 19 at 11 p.m. The bridge will remain closed through Monday, June 22 at 5 a.m. The closure extends from Montlake Boulevard to 92nd Avenue NE.
During the closure, WSDOT bridge engineers will test the main power supply to the bridge and inspect the mechanical systems. Bridge engineers will also perform ultrasonic testing on the drawspan‘«÷s vertical guide rollers.
‘«£The guide rollers help ensure the bridge can be opened smoothly and quickly,‘«ō said WSDOT Bridge Superintendent Archie Allen. ‘«£The ultrasonic testing allows us to ‘«ˇsee‘«÷ inside the steel of the guide rollers to make sure they‘«÷re in good condition.‘«ō
Crews will also clean and lubricate the drawspan‘«÷s tracks, repair potholes, clean out drains, repair electrical cover plates, perform preventive maintenance on the swing gates at mid-span and remove graffiti.
‘«£Doing this maintenance work while the bridge is closed for the inspection saves us time and money,‘«ō said Allen. ‘«£In a short amount of time, we can get a lot of work done that would normally require lane closures that could disrupt traffic for several weeks.‘«ō
WSDOT will release inspection results in mid-August.
Traffic closure details:
* Crews will close SR 520 from Montlake Boulevard E. to 92nd Avenue NE around the clock beginning at 11 p.m. on Friday, June 19, until 5 a.m. Monday, June 22.
* Seattle drivers will be able to use SR 520 from I-5 to Montlake Boulevard E.
