Closures coming to 2 busy Interstate 80 onramps in Placer County this weekend and next

Motorists who use Interstate 80 to commute from Placer County toward Sacramento and beyond should plan for detours this weekend and next as back-to-back 55-hour shutdowns come to two key Roseville freeway entrances.

The westbound I-80 onramp at Douglas Boulevard will be closed beginning at 9 p.m. Friday as crews continue freeway work for a $46.1 million project to construct an auxiliary and fifth lane, Caltrans District 3 said in a news release.

According to Caltrans, a fifth lane is being built on westbound I-80 between Douglas Boulevard and Riverside Avenue, and the work includes restructuring the Douglas off-ramp from two lanes to one.

Drivers looking to enter the freeway from eastbound Douglas Boulevard will be detoured to Sunrise Avenue before making a right turn onto Cirby Way and a left turn onto Riverside Avenue to make it onto westbound I-80.

With the temporary weekend, Caltrans cautioned drivers to be attentive as roadway workers excavate a portion of the freeway while installing new lighting and repaving the ramp.

Caltrans expects the Douglas Boulevard freeway entrance to reopen at 5 a.m. Monday.

Another closure is planned the following weekend — Oct. 11 through Oct. 14 — for the loop onramp that connects westbound Douglas to westbound I-80, Caltrans said.

Motorists there will have to detour north along North Sunrise Avenue before making a left turn at Eureka Road/Atlantic Street, followed by another left to access the I-80 slip road.

While the closures are temporary, work on the project is expected to continue until spring.
