State highway crews will close Colorado 9 just north of Alma at the base of Hoosier Pass for a week starting Thursday morning, potentially adding more than two hours of travel time for drivers, state transportation officials said.
Drivers headed toward that highway linking Alma and Breckenridge should detour along U.S. 24, Colorado 91, or Interstate 70, Colorado Department of Transportation Officials said in a news release.
For drivers, the detours may add 120 miles and 2 hours and 25 minutes of travel time, CDOT officials said.
They’re closing the highway in an effort to hasten work, keep crews safe, and minimize environmental impacts along Hoosier Pass as crews replace a structurally deficient bridge originally built in 1938, officials said. “For the safety of the traveling public, this structure requires full replacement.” The closure is scheduled to begin at 6 a.m. Thursday and continue through 6 a.m. on Sept. 14, depending on weather.
