I-80 Night Full Closure

I-80 will be completely closed in one direction at a time for four nights to jack the bridge and set the bridge in its new supports.

Each night’s closure will be limited to within a 5-hour window between 11PM to 4 AM. For each bridge then, there will be a total of eight nights of I-80 closure (four nights for each direction) and a total of 48 nights of I-80 closure for the entire two-year duration of construction on six bridges.
