Drivers should expect some delays along Highway 24 near Manitou Springs and the Waldo Canyon burn scar as crews work to install a new culvert.
Workers are installing a giant culvert to prevent water and debris from getting onto the highway. CDOT says the culvert will be 10 times larger than the one that currently exists under the highway.
Eastbound traffic is being shifted to the westbound lanes making it one lane in each direction.
The speed limit through the area will be 35 miles and hour.
Vehicles over 12 feet wide will not be allowed through.
CDOT says the new culvert should be able to handle the large volume of water that the Waldo Canyon burn scar can produce during flood season.
One the work on the eastbound lanes is done, CDOT will shut down the westbound lanes and do the same work on that side.
