Crews are back at work on North Bay roads after a holiday break. Work on the Highway 101 widening project around Petaluma is scheduled to shift traffic on the northbound Highway 116 overpass. The work was rescheduled from December due to weather.

Elsewhere, sewer work in Rohnert Park is closing part of Santa Alicia Drive, and normal road maintenance in Sonoma and Mendocino counties will cause some delays.

The details:

Petaluma: Construction continues for the U.S. 101/State Route 116 Interchange Project and the U.S. 101 Petaluma Boulevard South Interchange Project.

Traffic Shift for Northbound U.S. 101
Saturday morning, Jan. 11, Caltrans has scheduled a traffic shift for northbound U.S. 101 at the State Route 116 interchange. Northbound traffic will to be shifted to the left across the median to the southbound bridge. There will be two northbound lanes and two southbound lanes sharing the same bridge. After passing over SR 116, northbound traffic will shift to the right and return to the original roadway. This traffic shift will remain in effect until late 2014 while the old northbound bridge over SR 116 is removed and replaced with a new bridge.

Northbound and southbound lanes will be separated by a concrete barrier, and the speed limit in the construction zone will reduced to 45 MPH. It is essential for the safety of motorists and construction workers that this speed limit is observed. This speed limit will be enforced by the California Highway Patrol.

    When the article refers to the bridge over 116, it says “old”. But, it seems to me that the thing was just build, maybe 6 years ago????When was it built? Who is planning these things?

    The southbound bridge over Highway 116 was replaced about 10 years ago, but the northbound bridge is part of the original highway construction. The current project will replace the northbound bridge with a wider bridge but will not replace the newer southbound bridge.
