US-95: Culdesac Canyon Passing Lane

Adding a passing lane will provide drivers a safer opportunity to pass, while also improving capacity and mobility.

From 2019-2020, construction will excavate rock to make room for an extended passing lane. Nine culverts will also be upgraded to be more fish-friendly.

Season 1 summary
Asset 5
April 2019

Daytime blasting

Although most complete closures of US-95 will be scheduled at night, during the second week of April, traffic will be stopped in both directions to allow the construction of an equipment access trail above the rock slope. Rock and other debris will be pushed off the slope into a catchment area for cleanup. Drivers should expect delays of at least 15 minutes; if rock falls onto the road, delays could become longer as crews remove it.
