Sound Transit warns of drilling along light-rail line

March 27th, 2012 · 2 Comments

That next meeting about construction of Northgate Station can’t come soon enough.

According to an alert sent today by Sound Transit, geo-tech drilling started yesterday and will continue for a few weeks near the future North Link light rail line, along Interstate 5 from about Northeast 84th Street north to where the light rail tunnel will exit at Northeast 97th Street.

The purpose is to evaluate subsurface soil and groundwater conditions to help Sound Transit better understand the underground conditions. These drillings will take place at approximately 13 locations along the North Link alignment behind WSDOT’s fence or sound wall over the next few weeks.

What to expect

  • Hours of work: 7 a.m. to 6 p.m.
  • Drilling will take approximately two days to four days at each location lasting up to two weeks.
  • The hole will be drilled between 50-250 feet deep.
  • Drilling equipment will sound similar to a truck engine running with occasional hammering.
  • Pedestrians, bicycles, and motor traffic access around the drilling area will be maintained.
  • In some locations it may be necessary to restrict parking.
  • For more information about construction activities, call the 24-hour construction hotline at 1-888-298-2395 / TTY Relay: 711.
