If you're planning to travel down Colorado Highway 159 south of San Luis next week, you're going to need to add a little extra patience to your commute. According to the Colorado Department of Transportation, paving operations are set to begin on Tuesday, Sept. 9, and will continue through Wednesday, Sept. 10, as reported recently.

The work will start between Mile Points 2 and 4 on Tuesday, then move north between Miles 6 and 7 on Wednesday. Motorists can expect to be stopped fully and will likely have to wait up to 15 minutes as traffic alternates, guided by pilot cars from 7 a.m. to 7 p.m. each day. So, you might want to plan to leave early or find an alternative route to avoid the delays.

Here's what you need to know about the traffic impacts: Expect the work zone to enforce a 40 MPH speed reduction, and note that drivers entering the highway from a driveway or intersection will need to wait for a pilot car before they can join in the flow of traffic. All of these measures are part of CDOT's efforts to safely manage the paving operations and keep both the workers and drivers safe.
