According to Caltrans, only one southbound lane will be open from 10 p.m. Friday to 4 a.m. Saturday. Southbound lanes will be reduced to two lanes from 4 a.m. Saturday until 11 p.m. Sunday, and only a single lane will be open between 11 p.m. Sunday and 5 a.m. Monday, when the lane reductions cease.
In addition, the Telegraph Road off-ramp from the southbound 605 will be closed from 7 a.m. Friday to 6 a.m. Monday. The Telegraph Road on-ramp will be closed from 9 p.m. Friday to 5 a.m. Monday.
