State Route 49 All-Way Stop Control Maintenance Installation Order
Project Description
The intersection of State Route (SR) 49 and Shaws Flat Road is a four-leg intersection in Tuolumne County. Traffic along SR 49, approaching the intersection, is free-flowing in the northbound (NB) and southbound (SB) directions. Currently, the Shaws Flat Road eastbound (EB) and westbound (WB) approaches are controlled by LED STOP signs powered by solar panels.
Background
This intersection was identified through Caltrans’ routine statewide screening process for High Collision Concentration Locations. As a result, the District 10 Traffic Safety team conducted a detailed engineering investigation. It was determined that an All Way Stop with flashing beacons is the most effective, research supported measure to improve safety at this time. Caltrans continues to investigate other, long term improvements for this location.
Recommendation
- Install “STOP AHEAD” warning signs on both the and SB approaches to the intersection. Pavement markings will accompany the signs.
- Install two “STOP” signs at the NB and SB intersection approaches. Each location will include a STOP bar and pavement legend.
- All STOP signs will include an “ALL WAY” plaque to indicate that all approaches must stop.
- All new signs will be equipped with flashing beacons.
