A full highway closure remains planned for State Route 70 in the Feather River Canyon starting next week for a culvert replacement at Opapee Creek. This culvert replacement is a part of the emergency work following significant flooding and debris slides in the area in June. Crews will replace the existing six-foot diameter culvert with a ten-foot diameter culvert. A full highway closure is necessary for these operations due to the size of the hole for the new culvert and no room to safely have traffic pass through the area.
Subject to change, motorists should currently plan for the full highway closure to begin on Tuesday, September 6th at 7 a.m., with anticipated reopening to traffic by Tuesday, September 13th at 7 a.m.
The highway will be closed to through traffic between Jarbo Gap (west of Pulga) and the Greenville Wye (junction with State Route 89). Access will be allowed from either side of the closure, but not to cross the location at Opapee Creek.
There is no designated detour for this closure. Motorists are advised to check QuickMap for 24/7 updated highway information, including areas of road work and alternative routes. If traveling in a large vehicle, please check this website for highway restriction information. Please note that delays may increase on alternate routes due to road work and increased traffic volumes due to the SR 70 closure.
