The Oregon Department of Transportation is installing a traffic signal to control traffic at a location on US 101, north of Florence, where a landslide has damaged the roadway, leaving a single lane of travel. Installation of the signal began today. The signal will be activated by Wednesday, December 31, 2014. The signal will replace a pilot car in controlling travel in alternating directions at milepost 177, approximately 12 miles north of Florence, when construction is not occurring. The signal, operating on a timer, will reduce delays for all travelers by allowing traffic to move through the 500-foot-long single lane segment more quickly. Flaggers and possibly a pilot car will still be used to control traffic when the contractor is working at the site. During those periods, travelers should plan on delays no longer than 20 minutes.
