With electrical service upgrades to the Davis Water Treatment Plant, 3500 W. 35th St., slated to be completed in mid-December, all lanes will be open beginning Dec. 17. Crews will then begin installing new sidewalk from Foothill Drive to Hillview Road.

This phase of the project is expected to be completed by the end of January.
