Truckee River Bridge

Project Description

Caltrans News Release October 28, 2019 -- New Truckee River Bridge, Highway 89 Realignment Open to Traffic

The FHWA is the lead agency for the CA FLAP SR 89(1) Truckee River Bridge project.  The project includes construction of 2 new roundabouts and a new bridge over the Truckee River. New bike paths/bike lanes and sidewalks will also be constructed to improve safety and mobility for all modes of transportation in Tahoe City and the surrounding area and the project includes replacing a section of an existing sewer line.

78.5% of the project is funded by the Federal Lands Access Program (FLAP) and 21.5% in local matching funds provided by Placer County and the Tahoe City Public Utility District (TCPUD).

In the spring of 2019, the project team agreed to execute a partial contract termination.  This partial termination deleted work from the project that included the wye intersection, Fanny Bridge, and SR 89 between the Fanny Bridge and new Transit Center entrance.

Work to construct a new roundabout at the wye intersection, replacement of the Fanny Bridge, and rebuilding SR 89 between the Fanny Bridge and new Transit Center entrance may begin in Spring 2022 and completed in two to three construction seasons.

Interesting Project Facts

  • The FHWA and Caltrans' District 3 Maintenance Staff met to determine the minimum size roundabout suitable for snow plow and sweeper access. Using the minimum sized roundabouts ensured the least amount of impacts to the Tahoe Basin environment. Cones were set up to mimic the interior island diameter of the roundabout to allow snow plow operators to test drive the plows around the cones in order to determine the optimum diameter. This diameter was measured and then transferred to the final design and eventual roundabout construction.
  • The western roundabout was designed as an ellipse to reduce cost, right of way and environmental impacts.
  • FHWA utilized rockery retaining walls throughout the project to minimize environmental impacts. The small construction footprint eliminated right-of-way impacts and improved overall aesthetics.

Anticipated Timeline

Release of Environmental Assessment (EA): December 2014
Finding of No Significant Impact (FONSI): July 2015
Construction Dates:
  • 2017: Construction on the new Truckee River Bridge located east of the existing Caltrans maintenance yard along SR89 (River Street) began, grading of the new SR 89 roadway alignment and new transit center entrance was completed, and replacement of the sewer line along SR 89 was completed.
  • 2018:
    • Begin new western and eastern roundabouts under construction (completed in 2019)
    • New Truckee River Bridge and SR 89 Alignment between eastern and western roundabouts (completed in 2019)
    • Reconstructing a shared entrance to Caltrans Maintenance yard and Lumber Store
    • Reconstructing a new paved, trail alignment on both side of new Truckee River Bridge
    • Utility and drainage improvements
  • 2019:
    • Completed new SR 89, east and west roundabouts, and new bridge over the Truckee River
      • The new roundabouts, bridge, and roadway were open to traffic on October 28, 2019.
      • The construction contractor will continue to work on punch list item work, which is weather dependent.
  • 2020:
    • The contractor will be working on remaining "punch list" items through the 2020 construction season.

Status of Remaining Work:

  • The replacement of the Fanny Bridge and construction of a roundabout at the wye intersection will no longer be included in this construction project.  The project team agreed to execute a partial termination to remove this work from the construction contract. 
  • Work on the Fanny Bridge, wye roundabout, and SR 89 between the Fanny Bridge and new Transit Center has been programmed for FLAP funding in FY 21 and pending local match, could be constructed in the summers of 2022, 2023, and 2024.

Estimated Completion Date (West Roundabout, Truckee River Bridge, East Roundabout, new section of SR 89): Open to Traffic on October 28, 2019
