During the five-year construction, there will be some inconvenience to recreational activities and traffic. However, Antlers Boat Ramp will remain open and lake access through the construction zone will be maintained.

I-5 Antlers Bridge Replacement

The California Department of Transportation (Caltrans), in cooperation with the Federal Highway Administration, proposes to replace Antlers Bridge on Interstate 5 in Shasta County over the Sacramento River arm of Shasta Lake near the community of Lakehead. The bridge is at or near the end of its service life. In addition, a 0.4 mile section of highway south of the bridge will be realigned due to a high accident rate. Traffic will remain on the existing bridge during construction of a new bridge on a parallel alignment. New right of way will be required.

Antlers Bridge Project - Month of October 2014

Periodic day time closures are expected this month in the NB direction to allow for concrete trucks to safely exit and enter the highway. Utility and work trucks/pickups will also continue to enter and exit the northbound lanes on the south end of the project. Please be aware and reduce speeds when traveling through the project limits. Images of the progress can be viewed from the following:

The Antlers Bridge superstructure, or bridge deck, will be constructed using a form traveler system pictured here.
