Truckee – Caltrans is alerting Interstate 80 (I-80) motorists in Truckee of intermittent overnight off- and on-ramp closures due to construction work.  

A drone photo shows widening work along the eastbound shoulder of I-80 in Truckee, which will become an acceleration lane to improve safe vehicle merging onto the interstate. For the next two weeks, grinding and paving work will require interstate ramps at various locations to be closed overnight. Motorists may encounter off- and on-ramp closures between 6 p.m. and 8 a.m. Monday, August 22 through Friday, August 26 and Sunday, August 28 through Friday, September 2. Two consecutive off- or on-ramps will not be closed at the same time. Ramps subject to closure include:

  • I-80 westbound off-ramp to SR-89 south (Exit 185)
  • SR-89 south on-ramp to westbound I-80
  • I-80 eastbound off-ramp to SR-89 south (Exit 185)
  • I-80 westbound Central Truckee off-ramp (Exit 186)
  • I-80 westbound on-ramp from Central Truckee

In addition, motorists should expect intermittent day and night closures of the I-80 westbound loop on-ramp from Donner Pass Road and the I-80 westbound off-ramp to Donner Pass Road/Coldstream Road (Exit 184) throughout the week of August 22. Crews will be grinding and repaving the ramps and moving k-rail barriers.

The SR-89 south on-ramp to eastbound I-80 also continues to be closed around the clock through 5 p.m. Friday, September 2 for concrete work. Several concrete slabs are being replaced, which requires extended curing times before reopening to traffic.

I-80 westbound motorists should also expect around-the-clock closures of the #2 and #3 (middle and right) lanes from 8 p.m. Sunday, August 21 through 10 a.m. Friday, August 26 for polyester concrete inlay work. The lane closures will be in effect through the entire project limits between the I-80/SR-89/SR-267 separation and Donner Pass Road/Coldstream Road (Exit 184).

Motorists are reminded to expect travel delays on I-80 through November for construction activities. Typical delays of 15 to 20 minutes are anticipated when traveling through the work zones on weekdays. However, delays of 25 to 30 minutes are common on Thursday afternoons due to increased weekend travel levels.

The construction activities are part of a $30.6 million project to rehabilitate the existing concrete on I-80 in Truckee, install a westbound auxiliary lane from the SR-89 south on-ramp to the Donner Pass Road off-ramp, install eastbound acceleration lanes from the Donner Pass Road on-ramp and the SR-89 south on-ramp, improve drainage, and upgrade concrete walkways along ramps to meet current Americans with Disabilities Act (ADA) standards.

Teichert Construction of Rocklin is the prime contractor for the project, which is scheduled to be completed this fall. The construction schedule is subject to change based on weather, equipment or material availability, or other unexpected events.

The department will issue construction updates on Twitter @CaltransDist3, on Facebook at CaltransDistrict3 and on the Caltrans District 3 website. For real-time traffic, click on Caltrans' Quickmap or download the QuickMap app from the App Store or Google Play.

The project is rehabilitating concrete between the I-80/SR-89/SR-267 interchange and the Donner Pass Road Overcrossing. It is also adding a westbound auxiliary lane between the State Route 89 south separation and the Donner Pass Road Overcrossing, and eastbound accelerations lanes from the Donner Pass Road and State Route 89 south on-ramps.
