The Oregon Department of Transportation will be chip-sealing sections of U.S. 730 and Oregon 11 in Umatilla and Morrow counties, starting June 5, 2023

Medford, OR – According to the statement, the process reportedly includes spreading rock chips onto emulsified oil, then pressing the rocks in with rollers.

Chip seals help protect and extend the life of the existing roadway.
