Truckee River Bridge & Dollar Creek Trail

Martin Brothers Construction (MBC) successfully completed the Truckee Bridge and Dollar Creek Trail projects, demonstrating our expertise in complex civil infrastructure and environmental improvement. This project, commissioned by the Federal Highway Administration/Central Federal Lands Highway Division, aimed to alleviate seasonal traffic congestion, enhance safety, and address structural concerns along SR 89 and the SR 28/West Lake Boulevard interchange, including the deteriorating Fanny Bridge.

​

Scope of Work:

MBC performed an extensive range of operations to achieve the project objectives:

  • Mass Grading Operations: Comprehensive grading to prepare the site for new infrastructure.

  • Cut & Fill Operations: Earthmoving activities to create the necessary terrain for the new roadway alignment.

  • Environmental Improvement Project (EIP): Implementation of measures to protect and enhance the local environment.

  • Underground Construction: Replacement and installation of drainage systems, sewer system deletion and tie-in, and storm drain improvements.

  • Pavement Patching and Recycling: Rehabilitation of existing pavement to extend its lifespan and enhance safety.

  • Roadway Aggregate and Rockery Walls: Installation of road base materials and rockery walls for structural support and aesthetics.

  • Guardrail and Pedestrian Railings: Safety installations along the new roadway and pedestrian pathways.

  • AC Paving and Pulverization: Application of asphalt concrete paving and pulverization of existing surfaces to provide a durable road surface.

  • Drainage Improvement: Enhancements to the drainage system to prevent flooding and water damage.

​

Project Description:

The linear roadway project was designed to address seasonal traffic congestion and safety concerns along SR 89 and at the SR 28/West Lake Boulevard interchange, as well as to remedy the structural deterioration of Fanny Bridge.

Key components of the project included:

  • SR 89 Realignment: The realignment involved constructing a new two-lane segment of SR 89, crossing through a 64-acre parcel owned by the US Forest Service. This realigned section was built on an earthen embankment, with slopes designed and re-vegetated to integrate seamlessly with the surrounding forest.

  • New Roundabouts: A single-lane roundabout was constructed at the western end of the new alignment, serving as the new Hwy 89 roundabout. A second roundabout was built near the existing changeable message sign and sled hill to reconnect the realigned SR 89 to the existing highway.

  • Truckee River Bridge: A new bridge over the Truckee River was constructed immediately southeast of the new roundabout on the realigned highway segment, providing a critical crossing and enhancing connectivity.

  • Fanny Bridge Rehabilitation: The existing Fanny Bridge was rehabilitated or replaced to ensure long-term structural integrity and safety. This included necessary repairs and upgrades to extend its functional lifespan.

  • Local Street Conversion: The existing section of SR 89 between Fanny Bridge and the eastern roundabout was relinquished by the state to Placer County and transformed into a local street, improving local traffic flow and accessibility.

​

Outcome:

The completion of this project marks a significant improvement in traffic management, safety, and environmental sustainability in the region. The realigned SR 89 and the newly constructed Truckee River Bridge facilitate smoother traffic flow and reduce congestion. The environmental measures implemented ensure the project aligns with ecological preservation goals. Martin Brothers Construction is proud to have contributed to this vital infrastructure enhancement, showcasing our commitment to excellence and community development.
