What you need to know: U.S. 395 will fully close for 15 days within the Sonora Junction Shoulders Project while crews install two under-highway wildlife crossings, providing safe and sustainable passage for mule deer and other area wildlife.
September 5, 2024 – MONO COUNTY – Caltrans officials report that on Wednesday, September 4, U.S. 395 will fully close for 15 days between State Route 108 and just south of Burcham Flat Road while crews install two wildlife crossings underneath the roadway as part of the Sonora Junction Shoulders Project. Construction will be scheduled 24 hours a day during the closure, and no vehicles will be allowed through.
To assist drivers, Caltrans has set up the following detour:

Northbound U.S. 395 in Mono County:
- For northbound motorists heading to Nevada or beyond, the detour will start on State Route 182 in Bridgeport which turns into Nevada Route 338 across the state line. At the terminus of NV 338 in Wellington, NV, drivers will turn west on Nevada Route 208 toward Holbrook Junction.
- For northbound drivers traveling to State Route 108 (Sonora Pass), follow the detour route above and head south once you reach Holbrook Junction.
Southbound U.S. 395 in Nevada:
- Southbound traffic coming from Nevada can turn east on Nevada Route 208 at Holbrook Junction, take the NV 338 south from Wellington and follow it to its terminus at the state line. Here it becomes State Route 182, which connects with Bridgeport. This 54-mile detour is roughly 8 miles longer than the journey on U.S. 395 between Bridgeport and Holbrook Junction.
Southbound U.S. 395 from Sonora Pass/Monitor Pass:
- Those traveling over Sonora Pass and Monitor Pass toward Bridgeport and beyond must first head north on U.S. 395 through the communities of Walker, Coleville, and Topaz to reach Nevada Route 208 at Holbrook Junction. Head east on NV 208 which connects to NV 338, and travel south on the highway to reach Bridgeport.
Drivers should be aware there are no services available on the detour route. Anyone requiring fuel, food, or a charge should utilize services in Bridgeport and Walker/Coleville/Topaz before taking the detour. All four communities will be open for business throughout the closure.
Roads near the closure that will be accessible include:
- Twin Lakes Road in Bridgeport
- Buckeye Road west of Bridgeport
Roads that will be inaccessible during the closure include:
- Burcham Flat Road from the south side
- Little Walker River Road to Obsidian Campground in Humboldt-Toiyabe National Forest
Drivers should not attempt to drive through the hard closure because large sections of the roadway will be completely missing. Construction crews will be working 24 hours a day, 7 days a week until this phase of the project is complete.
Work schedules are subject to change due to traffic incidents, weather, availability of equipment or materials, or any construction-related issues.
Travelers are asked to be attentive to workers on the highway, slow for the cone zone, and move over whenever possible to remain clear of construction personnel and equipment. Be Safe and Be Work Zone Alert!
