Construction on the Foresthill Bridge began in late January 2011. Click here for a construction schedule overview. This famous bridge (the tallest in California) is located about one mile east of Interstate 80 on Foresthill Road, spanning the North Fork Canyon above the American River.  Built in the early 1970s, Foresthill Bridge is due for important construction improvements. Recent assessments of the bridge’s physical condition and age have determined that it is in need of a seismic retrofit and repainting. This estimated $74.4 million project will improve the bridge’s performance in a seismic event and integrity.

• Seismic retrofit of the bridge
• Painting
• Miscellaneous work:
• Replace the bridge rail
• Striping lanes and sealing of the concrete deck
• Construct new catwalk system for bridge maintenance

As with every construction project, traffic detours and delays may be inevitable. Construction crews will make every effort to minimize interruptions to traffic and impacts to neighboring communities, as well as keep community members and commuters informed of construction updates and route alternatives/detours.

The County of Placer owns, operates, and maintains the bridge, and will oversee this bridge renewal. Public awareness for the Foresthill Bridge Renewal is important to Placer County. Updates will be posted as construction progresses. You can also stay current by joining our
