02-2K000 Whiskey Creek Bridge Emergency Repair Project

The California Department of Transportation (Caltrans) proposes the Whiskey Creek Bridge Emergency Repair Project to replace Whiskey Creek Bridge, including the bridge deck and superstructure. The project is located on State Route 299 in Shasta County between Post Miles 13.55 and 14.58. The scope of work would include: - Widening State Route 299 from 33 feet to 66 feet to include a 15-foot-wide bike and pedestrian path on the bridge portion only - Excavating and constructing part of the existing abutments - An embankment reinforcement geogrid would be placed for road widening - Placement of 0.1-feet of Hot Mix Asphalt (HMA) and base quantities for widening and conforming earthwork to the new structure - Trestles would be installed temporarily for construction - Extending existing drainages and installing new drainage systems - Install new guardrail – Midwest Guardrail System (MGS) - Install new concrete barriers - Install new fencing along edge of pavements - Clearing and grubbing - Demolish the existing bridge superstructure - Construct a new raised island, with stamped concrete, at the Whiskeytown Creek Road intersection at PM 13.87 to better accommodate truck turns Proposed staging areas would utilize existing roadside pullouts within the project limits. No additional right of way would be acquired. The Whiskeytown National Recreation Area and road connection at Post Mile 14.50 would be utilized during construction for staging and would be paved after construction is finalized. Drainage improvements would involve upsizing two existing culverts at Post Miles 13.76 and 13.85 from 18-inch-diameter to 24-inch diameter and extending them to accommodate roadway widening. Overside drains impacted by the widening would also be replaced. New drainage systems would be added to accommodate drainage impacts due to the installation of new concrete barriers to protect pedestrians with drainage inlets of 18-inch-diameters and overside drains of 12-inch-diameters
