Traffic delays have begun on the El Portal Road to stabilize a rock slide area near Dog Rock (approx. 0.25 miles east of the western park entrance). The contractor works from sun-up to sun-down, Monday thru Friday, with up to 30-minute delays (except during the commuter hours of 6:30 and 8:30 AM in the mornings and 4:00 to 6:00 PM in the afternoon, when there will be a maximum of 15 minute delays). The contractor will have one lane traffic control with flaggers. This project includes rock scaling and bolting to help stabilize an area that slid during the December 30, 2010 storm and again during March's storm event. The current schedule is to have the work completed prior to Easter.
