A major downtown intersection will be without a traffic signal today and perhaps all weekend as fans flock downtown to watch NCAA tournament action.

The traffic signal at Eighth and Massachusetts is inoperable after contractors working for the city hit a power line as part of a project to install new tree grates along Massachusetts Street.

Lisa Patterson, a spokeswoman with the city, said crews are working to restore power to the traffic signal, but the work may not be completed until Monday. Power also has been lost to street lights in the area.

None of the work extends into the street, and both lanes of traffic are fully open. Stop signs have been installed at the four approaches to the intersection.
