As of Thursday afternoon drivers on UVP at Hummel Drive have traffic signals to be aware of.   With signals and pedestrian lights, the highly traveled intersection now has about twenty lights including left turn lanes and pedestrian walkways.   Neighbors have been requesting the traffic control system due to high traffic and the proximity of Righetti and Lakeview schools.  A couple of years ago, a 16 year old Righetti girl was injured in the crosswalk.  Other features include new sidewalks, curbs and gutters, and adjustments to flood control.   Cost of the project was just under one and a quarter million dollars.
