Overview
This Preservation Project paved 16 miles of Interstate 90 between George and Moses Lake to preserve the existing pavement structures, extend pavement service life, and improve safety by updating features including guardrail, striping and installation of new cable barrier in the median. It required grinding the driving lanes to remove ruts and overlaying the east and west bound lanes on I-90 with Hot Mix Asphalt. The project also paved the ramps and bridges at the Adams Road and SR 281 Interchanges and included improvements at the Winchester Wasteway Safety Rest Areas.

To avoid traffic restrictions over the busy 4th of July weekend, the paving was scheduled to be completed by July 1st.
