Plan ahead for 3 weeks of overnight closures on SR 99 in Seattle

SEATTLE -- You've been warned.

The Seattle Department of Transportation says drivers should expect full weeknight closures in one direction of SR 99/Aurora Avenue North, just north of downtown, for the next three weeks.

Crews will close one direction at a time to install street lights, traffic sensors and sign bridges.

The closures are part of ongoing work to build the road and ramp connections between Aurora and the north portal of the SR 99 tunnel.
