At 7 a.m. on a weekday, the slowdown starts just south of the Diekmann's parking lot. Southbound traffic on Highway 1 stops at a temporary signal, and one lane takes turns carrying cars both ways through the middle of town. At 3 p.m. the crews leave and the road goes back to normal. On Saturday morning it's as if none of it happened.
Caltrans has run that pattern every weekday since Tuesday, September 8, 2026, and its traffic notice expects the work to wrap up in December. So for the rest of the fall, Bodega Bay works on two schedules. Weekdays depend on one short stretch of Shoreline Road. Weekends don't. Meanwhile, the county's long-term answer to that dependence is already on the books. It's a harbor path built so people on foot or bike can skip that stretch of highway.
Where the Road Narrows, and Why
The one-way control and temporary signals cover Shoreline Road/Highway 1 from Bay Flat Road to Kent Avenue, Monday through Friday, 7 a.m. to 3 p.m. The Press Democrat's September 9 report puts the closed southbound lane between Taylor Street and Kent Avenue. That's the section of slope and pavement damaged by winter storms. Signals manage the longer stretch. The repair itself sits in the shorter one.
Locating it is easy. Caltrans' project page for the in-town slide repair says the slide begins a foot or two south of the Diekmann's parking lot. Diekmann's Bay Store is at 1275 Highway 1. That puts one of the best-known storefronts on the highway at one end of the work zone. According to the Press Democrat, Caltrans spokesperson Victor Gauthier said the agency is working with property owners and businesses, Diekmann's among them, to keep disruption down. Gauthier also said Caltrans is working with the owner of 1215 Highway 1 to connect the road to a parking pad on that property with a reinforced concrete driveway.
The ground is the reason. The same report says erosion along this section has caused the roadway and shoulder to deteriorate and sink. A retaining wall went in earlier in the year after a storm last December damaged the shoulder. Caltrans' project page explains why this job is slower than ordinary repaving. The planned wall is built in steps:
- Drill into the earth, in a few spots as deep as thirty feet.
- Lower steel cages into the holes.
- Pour concrete over the cages to form piles.
- Set the piles so they touch, which turns them into one continuous wall.
Caltrans has to do all of that within its existing right of way, which is why traffic drops to one lane. The Press Democrat puts the cost at about $1.5 million.
Bay Hill Road Takes the Overflow, Except for Trucks
Caltrans has electronic message boards near both ends of Bay Hill Road where it meets Highway 1, and it encourages drivers to use Bay Hill to skip the work zone. The agency's notice calls Bay Hill Road the detour route.
There's a limit. Trucks are not allowed on Bay Hill, which the Press Democrat describes as a narrow hillside street. Delivery trucks, moving vans and contractor rigs headed through town on a weekday stay on Highway 1 and wait at the signal. If you're scheduling a furniture delivery, a tradesperson with a big truck, or a propane drop on the harbor side of town, the 7-to-3 window is the one that matters. Saturday is a different trip.
The notice itself admits the end date could slip. Completion "may change depending on field conditions." Caltrans points drivers to QuickMap for real-time conditions, and that's the quickest check before a morning run into town. Don't mix this up with a separate Caltrans job. One-way control on Highway 1 just north of Valley Ford, for a drainage pipe replacement, was scheduled to end October 20 and has nothing to do with the in-town repair.
How the Week Lays Out Through Mid-November
Put the published schedules side by side and the fall week looks like this:
| Day | Highway 1 in town | Freedom Trax at Doran |
|---|---|---|
| Monday to Thursday | One-way signals, 7 a.m. to 3 p.m. | Not offered |
| Friday | One-way signals, 7 a.m. to 3 p.m. | Reservations 8:30 a.m. to 4:30 p.m. |
| Saturday and Sunday | No scheduled work | Reservations 8:30 a.m. to 4:30 p.m. |
Friday is the one day both schedules overlap. Leave by 7 a.m. or wait until after 3 p.m. and the highway is fully open, even then.
The Weekend Side: A Beach Crossing With a Deadline
Doran Regional Park started something new this season. Bay City News, via SFGate, reported that Freedom Trax formally launched at Doran the week of September 12, 2026. It's a motorized track system that carries a manual wheelchair over soft sand and other uneven ground. The rider stays in their own chair and steers with a joystick, which a companion can also run. About 50 people used it during a summer pilot, according to parks officials.
In the same report, Nubia Padilla, Regional Parks' accessibility and equity manager, said:
"The simple pleasures of a day at the beach -- crossing the sand, getting close to the water and exploring independently -- are now within reach for more visitors."
The calendar is tight. Reservations are free on Fridays, Saturdays and Sundays from 8:30 a.m. to 4:30 p.m., through November 15. After that the program pauses for winter and comes back in spring. Starting Friday, October 30, that leaves three weekends. The last day is Sunday, November 15. If a family member or friend who uses a wheelchair has been waiting to get onto Doran's sand, those are the remaining dates until spring. Book at 707-565-2041 or [email protected], and details are at SoCoParks.org/FreedomTrax.
Doran has three track systems, at $7,500 each, paid for by a California State Coastal Conservancy grant and Sonoma County's Measure M sales tax, which voters approved in 2018. That same Measure M money shows up in the project that matters most for the weekday half of the week.
The Path That Lets the Harbor Skip the Highway
The Bodega Bay Trail Coastal North Harbor segment is a planned 0.6-mile Class 1 trail from the Bodega Bay Community Center to Eastshore Road. It's designed as an alternative to Highway 1, with boardwalks over seasonal wetlands, and it's part of the 1,200-mile California Coastal Trail. That's according to a project presentation to the Sonoma County Transportation and Climate Authorities' Citizens Advisory Committee dated August 31, 2026.
The presentation schedules construction from September 2026 through June 2028, over two construction seasons. That's a planned window, and a walkable path is still more than a year away. The cost shows how seriously the county takes the idea. Planned construction funding is $348,000 from Measure M bike and pedestrian funds, $1,249,000 in local funds and $1,715,000 from other sources, about $3.3 million in all. Caltrans is spending about $1.5 million to hold one stretch of Highway 1 in place this fall. The county plans to spend roughly twice that on 0.6 miles that keep walkers and cyclists off it.
It also connects to what's already built. In December 2014, the Press Democrat reported a newly finished 0.47-mile Coastal Prairie Trail section linking the Community Center with the Bodega Dunes campground access road. The North Harbor segment starts at that same Community Center and runs the other direction toward Eastshore Road. Once both are in place, the Community Center becomes a hub with off-highway trail running both north and south.
So the signal near Diekmann's will probably be gone by the new year, and the weekday detour up Bay Hill with it. Most trips through the harbor still have to use one road, and the North Harbor path is the county's plan to change that.
If you own a vacation rental on the harbor side of town and your guest arrival notes still describe a straight shot down Highway 1, this is a good week to update them for the weekday signal and the Bay Hill detour.
