Minor roadwork is scheduled for state Route 9 at the east side of the Zion-Mount Carmel Tunnel on Tuesday.

The work will entail overlaying new pavement on an 800-foot section of highway and is anticipated to take from 9 a.m. to 6 p.m. One lane will remain open most of the time, but motorists could experience delays.

Although the project is expected to take a day to complete, weather or other unforeseen circumstances could delay or extend the project.
