Nighttime lane closures have been scheduled for southbound State Route 99 between Belle Terrace and Ming Avenue from Sunday, August 30 through Thursday, September 3. The two outside lanes are expected to be closed each night between the hours of 9 p.m. and 5 a.m. The nighttime closures are needed to clear the slope on the west side of the freeway in this area.
The westbound State Route 58-to-southbound State Route 99 connector ramp is scheduled to be closed during nighttime hours from Sunday, August 30 through Tuesday, September 1. The closures are expected to be in effect between 9 p.m. and 5 a.m., each night. The ramp closures are needed to remove the shoring required to widen the westbound separation bridge.
The two outside lanes on northbound State Route 99 between State Route 58 and Ming Avenue will also be closed on Sunday night from 9 p.m. to 5 a.m. This closure is needed to adjust the temporary concrete barrier rail along the roadway. One northbound lane and the northbound State Route 99-to-eastbound State Route 58 connector ramp will remain open while work is underway.
The contractor will also make adjustments to the temporary barrier rail along Wible Road on Tuesday or Wednesday next week. This work will only take a few hours to complete, but will require traffic control affecting both directions of traffic. Flagging personnel will need to stop traffic for up to five minutes at a time during this operation.
Construction schedules may be changed without notice due to unforeseen circumstances. The Thomas Roads Improvement Program apologizes for any inconvenience this work may cause the traveling public.
