Work well underway on Fifth Street Bridge

February 4, 2018 GMT

As motorists come and go over the existing bridge, an army of workers is making progress on the early stages of a new, $70 million span that will connect Yuba City and Marysville.

The new Fifth Street Bridge won’t be completed until 2020, but work is well underway.

“The new four-lane bridge and related improvements are estimated to provide a 5-minute travel time savings between State Route 99 and State Route 70 compared with a 2-lane bridge,” said Yuba City’s Economic Growth and Public Affairs Manager Darin Gale. “We last collected traffic counts in 2010 as part of our preliminary engineering efforts and found that approximately 32,800 vehicles per day were using the Fifth Street Bridge at that time.”


He said a new four-lane bridge and related improvements would carry approximately 95,000 vehicles per day.

Assistant resident engineer Paul Chang said the bridge will significantly reduce commuter bottleneck traffic during the morning and evening rush hours.

Chang shared some of the project details.

• Four large cranes, the largest being 350 tons, help move and position a series of 10-foot diameter piles that will support the new Fifth Street Bridge.

• Temporary pile casings are being installed and, once completed, will go about 100-feet underground and about 20-feet above ground.

• The bridge will be approximately 1,868-feet long, 76-feet wide and include two lanes in each direction and include a 10-foot wide bike lane.

• He said there will be the occasional and brief delays, with flaggers stopping traffic for about 5-minutes at a time, as the move equipment and material around the construction area.
