MARIN COUNTY — Caltrans announced that two-way traffic is flowing on State Route 1 in between Marconi and Millerton near Tomales Bay in an unincorporated part of the county.

Caltrans had been using one-way traffic control in the area since early in 2023 while crews finished their storm-damage repair project in the area.

The damage occurred because of the heavy winter storms in January of 2023. Workers replaced the drainage culvert and installed a retaining wall to rebuild the shoulder.

Please drive with caution. Slow for the Cone Zone and Be Work Zone Alert. Caltrans thanks motorists for their patience while we work to maintain our state's highways, bridges, and tunnels.
