Del Norte County honored its Redwood National and State Park employees Tuesday for their contribution to Caltrans' Adopt-A-Highway program.
The honor came in the form of a proclamation read during the opening of the board's meeting.
The celebration was part of a series of events that are being held in each of the state's 12 Department of Transportation districts.
In District 1, which includes Del Norte and Mendocino counties, 302 volunteer groups comprise the Adopt-A-Highway program.
The park employees volunteered for the program in June 2004, when they adopted a section of U.S. Hwy. 101 north of Crescent City.
They removed litter on both sides of the roadway, a doubling of their original effort.
The employees "have done an excellent job" of cleaning the northern entrance to Crescent City, according to a press release from Caltrans.
Besides the Redwood State and National employees; Mendocino Peace and Justice Center, and Carolyn and Toby Lurie were honored Feb. 22 for their contributions.
The program began in 1985, and has removed litter from more than 50 percent of the state highway system.
