Beginning today, Hwy 100 at the Rawson Avenue bridge will likely have some traffic issues, as the state begins its replacement of the bridges over Rawson. This year will be southbound bridge, with next year being the northbound bridge. As the bridges get replaced, the other bridge will be utilized to handle both directions, one lane apiece. Due to this, I wouldn't be surprised if there was traffic backups during rush hour.
The southbound bridge is expected to be completed by mid-November.
