Topanga Canyon Boulevard (SR-27) remains closed to the public for safety reasons between Pacific Coast Highway and Grand View Drive due to the recent rain. Areas were washed out and now need structural repair and cleanup in addition to repairs for fire-related damage. As Caltrans works to restore the road, it will maintain access for emergency responders and is exploring options for limited access, when safely feasible. There is no estimated time of reopening. Another safety threat was the recent discovery of a large boulder, measuring 30 feet by 15 feet by 10 feet, which is in an unstable position above the roadway between postmile 2.1 and 1.7. On Monday, February 24, crews were able to successfully blast the boulder and resume clearing of SR 27. Utility companies are continuing major repair work, including rerouting a main water line and underground electrical work, which will impact the shoulder and lane. This will require one-way traffic control for contractors. Prior to the recent rain, Caltrans geotechnical engineers identified more than 20 locations along SR-27 that need debris flow barriers and culvert replacement. Additional work and safety measures, such as scaling and installation of rockfall cable mesh, are needed to restore slope stability and roadway safety. Although reopening the roadway is dependent on cleanup, repair work and weather, Caltrans stands ready to execute a reopening plan in coordination with the CHP, utilities, and any affected public agencies as soon as it is safe to do so.
