The westbound State Route 58 to southbound State Route 99 connector will be closed during the nighttime hours from December 15 until December 17. This closure is scheduled between 9 p.m. and 5 a.m. The closure is needed for tunnel shoring.
During these closures, westbound-to-southbound motorists will be detoured to northbound State Route 99 connector to exit at California and then enter on the southbound State Route 99 on-ramp.
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.
