197/199 Safe STAA Access

The 197/199 Safe STAA Access Project aims to upgrade sections of Route 197 and U.S. 199 in Del Norte County to meet the standards for STAA truck routes. These improvements involve widening lanes and adjusting curves to accommodate larger trucks while enhancing safety for all travelers. Currently, these areas pose risks due to narrow lanes and limited visibility, leading to potential accidents. By making these enhancements, the route can facilitate safer and more efficient movement of goods between Crescent City and Interstate 5 (I-5), benefiting both truck drivers and other road users.

Aerial map of the Route 199 and Route 197 corridors between the U.S. 101 and Oregon border. Seven locations are marked. Ruby 1 and Ruby 2 on Route 197 and Patrick Creek Narrows Location 1, The Narrows, Patrick Creek Narrows Location 2, Patrick Creek Narrows Location 3 and Washington Curve on Route 199.

Purpose and Need

The purpose of the proposed project is to construct improvements at spot locations along Route 197 and U.S. 199 in Del Norte County to allow the reclassification of the corridor as part of the industry standard STAA network of truck routes. These improvements include widening lanes and modifying curve geometry at identified locations to accommodate standard STAA-sized vehicles while maintaining and improving safety for the traveling public.

All seven locations included as part of the proposed project have roadway geometries that can result in STAA trucks and other long-wheelbase vehicles off-tracking across the double yellow line and entering the oncoming traffic lane. Additionally, limited sight distance at all seven locations does not allow enough time for drivers to react to roadway conditions ahead. Lack of STAA truck access on the 197/199 corridor restricts options for goods movement between Crescent City and I-5. Safety-enhancing improvements, including wider lanes, wider shoulders, longer radius curves and improved sight distances are needed to provide a roadway that is safer and easier to maneuver for all users.

Timeline

Construction is currently estimated to begin in summer 2025.

Traffic Impacts
