ROSEVILLE, Calif — Construction started Tuesday for a project along Interstate 80 in Roseville and Rocklin.
The project includes adding a fifth lane on westbound I-80 east of Douglas Boulevard and west of Riverside Avenue. The Douglas Boulevard off-ramp will go from two lanes to one lane. On eastbound I-80, there will be an auxiliary lane between Highway 65 and Rocklin Road and a two-lane off-ramp.
Caltrans said these changes will help with improving traffic flow along with safety.
Caltrans says this corridor has had a history of crashes and congestion. Caltrans estimates 82,000 people commute between Placer and Sacramento counties each day, and anticipate about 78,000 residents will move to the area by 2036.
Jeremy Linder, with Caltrans District 3, said the project is a collective effort between the Placer County Transportation Planning Agency and Caltrans.
“This is our way of looking at the facility as a whole. What can we do to improve traffic flow, improve safety and get everyone home — either to their jobs or back to their loved ones for dinner in time,” Linder said.
The total project is expected to cost nearly $50 million. It's funded by a combination of federal, state and local funds.
Construction is expected to wrap up by July 2024, according to the construction page.
