SANTIAM CANYON, OR -- A major cleanup along Highway 22 in the Santiam Canyon is continuing. ODOT’s Peter Murphy says the canyon was devastated by wildfires that destroyed homes and businesses in several communities. He says they have been removing thousands of hazardous trees over the last month and a half.  Murphy says the estimated cleanup cost is about 600-million dollars and will take about 18 months to complete the work. He says if you’re travelling Highway 22 it will be a slow-go with a speed limit of 40-miles an hour as well as the possibility of delays due to the clean-up effort blocking the highway from time to time.
