Linda Tucker with the city's Transportation Department says motorists will notice some pretty big changes to their commutes along half-a-dozen major traffic corridors.
"They're going to see, when this is all done, their drive-time reduced somewhere between 10% and 20%, especially during peak times."
Crews are installing fiber-optic networks, cameras and new signal timing equipment. Staff will then be able to better coordinate traffic lights remotely at the city's Traffic Operations Center.
"It's like a control room fitted with very large monitors where they can control traffic on the fly if they need to."
The six corridors being upgraded include more than 70 intersections. Work will begin this week along Power Inn Road near Fruitridge. Other corridors include stretches along Florin Road, 65th Street and West El Camino Avenue.
Most of the funding for the $4 million project comes from state bonds along with some federal and local monies. The project should be completed by next spring.
