GOVERNOR HALTS TUNNELLING ON RECENTLY RESUMED SEATTLE TUNNEL

摘要

Washington governor Jay Inslee suspended tunnelling on the SR99 tunnel project 14 January, pending the investigation of a sinkhole. The Washington State Department of Transportation (WSDOT) said a sinkhole developed within contractor Seattle Tunnel Partners' work zone near South Main Street, about 35ft (10.7m) north of the access pit, at approximately 9pm Tuesday night. It is located more than 100ft (30.5m) south of the cutterhead's current location, in ground that crews mined through last week. STP filled the sinkhole overnight with 250cu.yd. (191cu.m) of concrete.
