I-84, Purple Sage Bridge Rehabilitation

The road surface on the bridge will be rehabilitated

Crews will mill off the top layer of the existing asphalt. Then, using high-powered water pressure, a process called "hydroblasting," the top layer of the bridge deck will be removed. Fresh concrete pavement will be laid down to create a new surface and extend the life of the bridge. New asphalt on the approaches to the bridge will ensure a level transition between the road and bridge.

Traffic Impacts

Traffic on both eastbound and westbound I-84 will be reduced from two lanes to one lane. Speed limits will be reduced to 65 MPH. Width restrictions may be in effect throughout the project. Concrete requires several days to cure before traffic can drive on the new surface. The reduced travel lane may be in place to allow for curing, even if workers are not actively on-site.
