For those who want to see what the work actually looks like, King County posted the above video on Youtube.com which goes inside the Ballard Siphon Replacement Project tunnel.

King County also provided us with an update. At the South Site, tunneling continues 24 hours a day, Monday through Saturday. Construction of the pipe to connect the new siphon to the existing system continues during typical work hours from 7 a.m. to 6 p.m. weekdays.

At the North site, work is nearing completion on the structure that will connect the existing sewer pipes to the new siphon. Crews are also preparing the north shaft for receiving the tunnel boring machine.

the tunneling is expected to be done in early summer of 2013. King County urges drivers and bicyclists to continue to use caution near the site.

• Activity on the project site involving equipment and trucks 24 hours a day, Monday through Saturday
• Increased night truck traffic around West Commodore Way
• Additional nighttime noise and lighting

What to expect at the north site, at 20th Ave NW and Shilshole Ave NW:
