Closure Date Road Name / Description

Mason County Public Works would like to notify motorists that roadway restriping on many major county arterial roads in Shelton will begin on August 23rd through the month of September, Monday through Friday and some Saturdays (weather permitting).
Most of our County roads are restriped every year to improve night-time visibility of pavement markings. This year, Specialized Pavement Marking, Inc. out of Tualatin, Oregon has been contracted to complete the project and the County Sheriff’s Department will be providing added traffic safety during operation.
Motorists advised to expect delays, use caution while driving through the striping operation and not to drive across painted lines.
The County appreciates motorist taking extra care while this road work is in progress.
For a complete list of county roads being restriped please visit the County Web site at, under “Public Works”, or call the Public Works Department at (360) 427-9670, Ext. 450.
