Truckee – Caltrans is alerting State Route 89 (SR-89) motorists in Truckee of an upcoming extended closure of the SR-89 south on-ramp to eastbound Interstate 80 (I-80).

The SR-89 south interstate entrance is scheduled to be closed around the clock from 5 a.m. Monday, August 15 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. During the closure, a signed detour will direct motorists along Donner Pass Road to Coldstream Road for access to the I-80 eastbound on-ramp.

In addition, I-80 east- and westbound motorists should expect intermittent lane closures Sunday night through Friday morning next week between Central Truckee (Exit 186) and Donner Pass Road/Coldstream Road (Exit 184) for roadway widening and individual concrete slab replacement work.

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 in 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.
