Highway 1 Bypass Directions

Back to Public Page

During the winter storm season, expect to see flooding on Highway 1 (Petaluma/Valley Ford/Bodega Highway) just east of Valley Ford, typically in two locations. Below are instructions for bypassing these flooded areas as well as a map.


At DiNucci's Italian Restaurant at the west end of Valley Ford, turn right onto Estero Road. In about one mile, you will cross a creek and very shortly thereafter Marsh Road. Continue on Estero Road for another mile until Estero Road branches off to the right. Leave Estero Road and stay on the main Valley Ford/Franklin School Road for another 1 1/2 miles.

Turn eastbound on Whitaker Bluff Road. (If you cross a bridge, you have missed the Whitaker Bluff Road turn by going about 1/4 mile too far.) In a little less than a mile down Whitaker Bluff Road, you will intersect Middle Road. Do not turn left (north) onto Middle Road. In about 0.1 mile, you will find another intersection with a right turn to Middle Road. Do not take that turn either, but turn left to stay on Whitaker Bluff Road (a.k.a. Fallon/Two Rock Road). Continue for another 1 1/4 miles, at which time you will intersect and cross Highway 1 (Shoreline Highway) which also goes to the Valley Ford Road, but it is a low route and is quick to flood.

In less than 1/2 mile, turn left (north) on Gericke Road (a.k.a. Jones road). Continue on Gericke Road for about 2.8 miles to intersect Valley Ford Road. Turn right to resume the trip to Petaluma via Valley Ford Road.

That should have gotten you around the worst of it. Both Shoreline Highway and Middle Road have low spots and are often flooded. Resist the temptation to take them.


Usually, any serious flooding on Valley Ford Road occurs in several low spots between Carmody Road and Valley Ford. These instructions bypass those flooded areas.

Turn left (south) at Carmody Road for almost three miles to the dead-end intersection of Fallon/Two Rock Road (left turn) and Whitaker Bluff Road (right turn). Turn right on Whitaker Bluff Road. In less than one mile, you will cross Highway 1 (Shoreline Highway). Continue on Whitaker Bluff Road for another 1 1/4 miles until you reach Middle Road.

Before proceeding, stop and read this paragraph carefully. For about 0.1 mile, Whitaker Bluff Road becomes Middle Road and then it resumes as Whitaker Bluff Road. You are to continue on Whitaker Bluff Road as directed in the next paragraph.

Turn right (north) on Middle Road (you will also be on Whitaker Bluff Road). Proceed about 0.1 mile while the road turns left and until Middle Road turns off to the right (north) and Whitaker Bluff Road continues westbound. Do not follow Middle Road, but continue westbound for one mile on Whitaker Bluff Road until it intersects and becomes Franklin School Road. Continue on Franklin School Road as it winds around and merges with Estero Road. Do not turn west (left) on Estero Road, but continue northeast on Estero Road/ Franklin School Road for 1 1/2 miles as it passes the Marsh Road intersection and crosses a bridge to join Highway 1 just west of DiNucci's Italian Restaurant located at Valley Ford’s west end.

That should have gotten you around the worst of it. Both Shoreline Highway and Middle Road have low spots and are often flooded. Resist the temptation to take them.

(The yellow route on the following map shows the use of Gericke Road rather than Carmody. Sometimes there is flooding between Carmody and Gericke, so these directions suggest Carmody.)
