Changes will be coming Monday night to one major southern Colorado highway. CDOT is ready to shift traffic on Highway 50 at Pueblo Boulevard in Pueblo.

It could cause big changes to your daily commute. Tuesday morning, drivers will be driving on the new lanes as they head west on the highway.

One of the biggest changes that drivers will need to pay attention to is that they will not be able to turn left onto Pueblo Boulevard from the highway. Instead there will be an off ramp. The off ramp will be the old Highway 50.

CDOT said this project will help with two things: congestion and safety.

"We were seeing a lot of people take this area, so we were seeing congestion not only during the peak morning and afternoon hours but throughout the day. So it was time for the road to be widened,” said Michelle Peulen, a spokesperson for CDOT

They did widen the section from the railroad bridge to just past the top of the hill that is further west of Pueblo Boulevard to three lanes. This traffic shift is just for drivers heading west on Highway 50. There is no change to the eastbound lanes.
