The Washington State Department of Transportation was kind enough to release the following time-lapse video of construction on Highway 99. The video shows crews working through the night to demolish and replace the section of SR 99 that crosses above Broad Street.
“We thank commuters for their patience and their help,” said Dave Sowers, WSDOT’s deputy administrator of the Alaskan Way Viaduct Replacement Program. “We know there were some difficult commutes during the weekday portion of the closure, but we also know if people hadn’t changed their habits, things could have been much worse.”
WSDOT said crews replaced 81 concrete panels on SR 99 south of downtown, repaired an expansion joint at the Seneca Street off-ramp, and cleared ivy from the Alaskan Way Viaduct.
If you like that time-lapse video, you’ll likely LOVE this time-lapse video of a bridge being replaced in Connecticut.
