Idaho Falls Power work crews will replace a damaged traffic signal pole Thursday on the northeast corner of St. Clair Road and 17th Street. The pole was damaged when a vehicle crashed into it Tuesday. 

During the course of the work, motorists will see a flashing yellow indicator on east and west bound lanes of 17th Street.  St. Clair will be closed to all through traffic in both directions between 16th and 17th Streets.

The work is expected to begin around 7:30 a.m. and take about three hours to complete.
