Some relief is coming for drivers tired of dealing with the Highway 101 construction from Rohnert Park to northern Petaluma.

Caltrans spokesman Robert Haus said, weather permitting, the agency plans to open up in mid- to late November the extra north and southbound lanes on 101 from Rohnert Park Expressway south to Petaluma Boulevard North, making 101 three lanes in each direction.

But the highway will remain only two lanes in each direction from Rohnert Park Expressway north to Santa Rosa Avenue, and that stretch is not expected to be widened until late 2012 because crews need to finish building the new Commerce Boulevard-Wilfred Avenue overpass. So there will be traffic bottleneck at times north and southbound there.

Haus said the remodeled highway from RPX to Petaluma Boulevard North likely won’t be completely finished when the new lanes open, so there might be some uneven pavement and drivers will have to pay extra attention. Final paving and other finishing touches would be done after the rainy season.

He said the pre-finish opening will be similar to what Caltrans did a couple of years ago in the stretch of 101 from north Santa Rosa to Windsor: Letting drivers use the extra lanes before the entire project was complete.

    You are not going to get an extra lane; All you get is a lane that gets hardly any use because it a HOV lane, while the other two lanes just creep along like before. And of course the CHP gets another trap to ticket everyone that tries to take advantage of a lane that we all pay for but only a few use.
    Why do we put up with these burecrats stupid ideas?

    Whatever you do don’t get a ticket. The Sonoma County Traffic Pay by website has been down for over a month. They have a note saying it works most of the time but it hasn’t worked in over a month and they have the same message posted. Sad that Sonoma County can’t provide these simple services to the community. Another sign of government ignoring the public.

    They will offer you an extension by email but, you will have to go in to pay. Whomever is responsible for this site being down, please update your messages on the website at least and tell the truth. Also it’s 2011, can’t be that complicated to fix this simple website!

    I totally agree! HOV lanes are a dinosaur of the past and need to be abolished. In this day of high fuel prices, people do everything they can to reduce fuel consumption. HOV lanes are no longer part of any solution but a part of the problem.

    HOV lanes don’t work. Studies have shown this to be true. And why and children even considered carpoolers? A carpool should be people of driving age.

    HOV lanes might seem unfair if you choose to drive alone, but they’re actually more efficient both in terms of moving people and reducing fuel consumption because they encourage people to carpool and ride the bus. Even when HOV lanes LOOK empty compared to bumper-to-bumper car lanes, they’re often carrying more people because they aren’t just stacked up with mostly empty vehicles like the regular lanes are.

    And it’s silly to say they’re not for everyone, because anyone can use them if you just make different decisions about how to get around.

    One for Road Warrier: Please drive down Cavanaugh Lane (off Skillman) in Petaluma. You may just find this road WORSE than Lichau Rd. With apx. 100 BIG trucks using this lane per day, it’s getting REALLY BAD, and it’s not even officially winter, yet. The holes are DEEP in places, no one taking care of this problem, this road not equiped to handle a trucking distributorship tearing up a lane. Thanks, and hope you can check it out.
