The Denver Post reports, beginning Sunday, the state Department of Transportation will close U.S. 6 between Golden and Colorado 119 through the work week until June 29.
The closure starts at 11 p.m. every Sunday and extends through every Friday at 10 a.m.
That means kayakers won't be able to get to the area during the week at a time when ideal conditions are expected to quickly vanish. CDOT plans to keep U.S. 6 open from 10 a.m. May 24 until 8 a.m. May 29 for Memorial Day weekend.
The department also will escort rafting companies to spots along the canyon, but individual kayakers will have to wait for the weekend openings.
