Document Description
Installation of a highway advisory radio (HAR) system on State Routes 139 and 299 in Modoc and Lassen Counties near the community of Adin. The HAR system will advise motorists of adverse road conditions. The antenna and transmitter will be installed at the Caltrans Adin maintenance Station on route 299 near the Lassen/Modoc County line. The three HAR signs will be placed at the following locations: 1) Modoc Route 299 post mile 1.33 facing westbound traffic, 2) Lassen Route 299 post mile 24.89 facing eastbound traffic, 3) Lassen Route 139 post mile 65.65 facing northbound and southbound traffic. Electrical and telephone service connections will be needed for each sign. Utilities will be extended to each site via underground conduit from existing utility poles. Minor earth disturbance and vegetation removal will occur due to trenching for conduit and excavations for equipment pads and sign posts. All work will be confined to State right of way except for a utility easement on Route 299 in Lassen County at post mile 1.33. Paved pullouts will be constructed at each sign location for maintenance vehicles.
