The California Highway Patrol, in conjunction with California Department of Transportation, will increase speed patrols on Highway 44 between Dana Drive and downtown Redding.
"People weren't slowing down," said Denise Yergenson, a spokeswoman with Caltrans.
The speed limit in the construction zone, known as the Dana to Downtown project, had been reduced to 45 mph to protect motorists as well as workers, Yergenson said.
The road is planned to be re-surfaced and striped Tuesday and Wednesday. This will help with lane clarity, Yergenson said.
In addition, evening construction will start at 7:30 p.m. instead of 9:30 p.m. in an effort to decrease late-night noise. Lane closures will also start at this earlier time, she said.
