Tunneling crews continue to make progress on both tunnels between the Roosevelt Station site and the U District Station site for the Northgate Link Extension in Seattle.

TBM Brenda is just south of NE 50th Street and Pamela is north of NE Ravenna Boulevard. Brenda is expected to arrive at the U District Station site in October and Pamela by early next year.

Crews continue to pour the concrete base and install drainage in the future northbound tunnel between Roosevelt Station and the Maple Leaf portal. Click here and us/42 for tunnelbuilder archive.Visit http://www.soundtransit.org/ . 40/15.
