A 34-hour closure of the eastbound 210 Freeway in Pasadena is slated to begin Saturday night and continue through the weekend.
The closure, dubbed “Rose Jam,” was scheduled to begin at 7 p.m. Saturday and continue until 5 a.m. Monday, according to a Caltrans notice.
Construction activity will require the closure of the eastbound lanes from Mountain Street to Lake Avenue.
The eastbound 210 connector to the westbound 134 Freeway will also be closed for the weekend, according to the notice.
The closure is part of a $148.5 million pavement project to provide a smoother ride for motorists.
The overall project, which is being completed in several stages, also includes the cities of Glendale and La Canada Flintridge, and should be completed in 2019, according to Caltrans.
Motorists were warned to expect delays and be on the lookout for posted detour signs.
Meanwhile, another freeway closure was expected to impact drivers on the 101 Freeway between Glendale and Cahuenga boulevards Sunday through Wednesday nights.
Both sides of the highway will be closed alternately from midnight to 5 a.m. while crews install loop detectors into the pavement, officials said.
