The downtown Seattle bus tunnel will stay closed until further notice because of computer problems.
Buses that usually use the tunnel will continue operating on downtown surface streets.
Metro closed the tunnel Dec. 17, reopened it Dec. 18, then closed it again Dec. 19. It has remained closed.
The computer system, installed this year, is designed to let operators control signals, ventilation, elevators, security cameras and lights from a control center near Safeco Field in an emergency.
