Project:Highway 12 Solano Co. Roadway Rehab, $23M
The safety improvements and roadway rehabilitation project involved widening and profile correction on Highway 12 from Walters Road in Suisun City to Currie Road, west of Rio Vista. The two-lane road across rural rolling terrain significantly improved safety and stopping distances of this segment by providing standard 12-foot lanes and 8 foot shoulders, adding left-turn lanes and placing channelizers and rumble strips, and correcting vertical and horizontal profile characteristics within the Montezuma Hills. The project faced environmental challenges due to its proximity to the Delta, Sacramento River and Carquinez Straits and its endangered species such as the red-legged salamander.
“The most valuable parts of the partnering sessions were opening communications to
another level and group interaction, particularly discussing challenges and solutions.”
