Starting the night of September 3, 2013, Caltrans will start construction of a project along Interstate 680 through the City of Pleasant Hill (between Monument Boulevard and the I-680/SR-242 split) to replace broken concrete roadway surface slabs and to smooth out the concrete surface to reduce the amount of noise perceived by the surrounding neighborhoods.
Due to the heavy daytime traffic on I-680, project construction work must be performed at night. All three phases of work (demolition of broken concrete slabs, grinding operations, and final grooving) are noisy activities in the immediate vicinity of work area. Construction vehicles and operations will also contribute to higher levels of noise for adjacent neighbors during the construction period. Caltrans will monitor the noise and work with City residents to address their concerns during the construction period.
Depending on the location of work along the freeway, I-680 off-ramps and on-ramps may be temporarily closed during project work hours with detours established through city streets.
Caltrans advises that during project construction periods, all residents be on the alert for workers, signs, and reduced speed zones near the construction area.
Information regarding road closures will be sent to the media and posted on the Caltrans website at www.dot.ca.gov/dist4.
