Horse Creek Bridge Replacement Project on State Route 96 in Siskiyou County

Published: Jul 17, 2024

Caltrans District 2 and contractor Myers & Sons Construction have recently begun construction on the Horse Creek Bridge Replacement on State Route 96 in Siskiyou County. The project will replace the Klamath River Bridge near Horse Creek on a new highway alignment, addressing current soil erosion around the bridge foundations and increasing vertical and horizontal clearance for trucks and freight haulers moving goods through the area.

The new design also features larger eight-foot shoulders and a bicycle railing, enhancing safety and accessibility for pedestrians and bicyclists. Worker safety will be improved by significantly reducing or eliminating the need for crews to scale the steep structure to fix damage caused when larger trucks or their freight loads impact the overhead bridge truss.

Early work on the project, which began last week, includes vegetation removal, abutment work, fencing, and erosion control. A temporary driveway access into Conner's Quarry is also under construction, with the existing driveway being used for bridge construction access.

Slope excavation for the new alignment is currently planned in August, which will include rock blasting operations. Motorists are advised to be prepared for one-way traffic control with up to 6-minute delays typically, Monday through Friday during daytime hours. On days when blasting operations are planned, motorists should allot up to 30-minutes for delays.

Once slope excavation operations are completed, traffic delays on the project are planned to be minimal, as most of the work will occur on an adjacent alignment. Motorists are reminded that the law requires them to slow down, obey temporary speed limit reductions, and drive carefully in and around construction areas. This multi-year project is currently planned for completion in late 2025 and will go into suspension during winter months.
