New bridge between I-5 and SR 411

Cascade Bridge Inc.

Recent Progress

Contractor has completed the installation of a temporary work platform that spans across the river.  This will allow access for the equipment needed to install the bridge foundations.

Environmental Impacts / Compliance

The contractor has completed the initial work platform which required the use of "bubble curtains" to minimize impacts to the endangered species.
