Document Description
The CA Department of Transportation (Caltrans) is proposing to make improvements to ten existing chain control turnouts on U.S. 395 and build two new chain control turnouts; one on U.S. 395 near the SR 203 intersection (Mammoth Lakes) and the other on U.S. 6 near Slim Princess Road. Due to increased traffic during winter weekends and holidays, existing chain control turnouts can become crowded during peak times. Improvements to existing turnouts include new chain control signs with attached flashing beacons, expanded pavement areas, and the addition of twenty-three solar or conventionally-powered lights. Additional lights at chain control turnouts are proposed on future Caltrans projects, and cumulative impacts are discussed in this document.
