Seasonal closure of dirt roads in the Eldorado National Forest will occur Nov. 29 due to anticipated heavy rainfall.

They will remain closed until at least April 1.

Rainfall, soil moisture, road and trail conditions, and weather forecasts are factors that trigger a seasonal closure earlier than Jan. 1. Officials say many of the roads are on the edge of being too wet to drive on and the high probability of severe weather makes the pending seasonal closure a sensible decision.

Roads subject to seasonal closure are identified on a map that is free and available at all Eldorado National Forest offices and online.

The seasonal closure does not affect routes in the Rock Creek Area of the Eldorado National Forest near Georgetown, which has its own route closure process.
