The lanes will be closed from 9 a.m. to 3 p.m. Monday through Friday. According to the city, the eastbound side of Sand Hill Road will carry traffic in both directions during PG&E's working hours.
The pipeline replacement started on Aug. 15 and should finish by the end of October, according to Menlo Park Public Works Director Chip Taylor. A segment of pipe across Alpine Road, south of Sand Hill Road, will also be replaced.
Once the new pipe is in place, the utility company is required to repave the portion of Sand Hill Road within the project boundaries.
