Carbondale’s roundabout now open

The long-awaited opening of the new roundabout at State Highway 133 and Main Street in Carbondale is slated for today, although construction will continue at the intersection and along the 2-mile stretch of highway into November.

Navigating the Roundabout

Colorado Department of Transportation and the town of Carbondale offer the following roundabout navigation tips as the new Highway 133 and Main Street roundabout opens:

• Observe all standard road rules, including yielding to pedestrians in crosswalks.

• Slow down.

• Read advance signing and choose correct lane before entering the roundabout.

• Yield to all traffic in the roundabout before entering.

• Stay in your lane to your exit.

• Cyclists should stay in the lane and not hug the curb.

• Pedestrians or cyclists using the sidewalk should cross only at designated crosswalks, wait for a safe gap in traffic, and cross only when traffic yields or stops.

A major step toward the completion of the State Highway 133 improvements later this fall happened Monday morning, when Colorado Department of Transportation officials opened one lane of the new roundabout at 133 and Main Street to traffic.

Access to West Main Street and the south entrance into the 7-Eleven store, which have been closed since early August, is also open. The north access to 7-Eleven will now be closed.

At the same time, the Colorado Avenue access onto Highway 133 will now be closed for a period of time to allow for continued road construction at that intersection, according to CDOT officials. The temporary traffic light that has been in operation at that location will be removed.

Until now, Carbondale has been the only community in the Roaring Fork Valley that didn’t have a roundabout, which have become more common as a way to better regulate traffic flow through busy intersections.

“This is a major step toward concluding the project on time,” Graham Riddile, CDOT project engineer, said in a news release. “We are excited for Carbondale residents to now be able to utilize the roundabout and proud to have reached this milestone on the project.”

One lane of traffic will be open in all directions through the new roundabout starting Monday. However, work will still continue on the second lane and other parts of the roundabout structure.

For safety reasons, pedestrians should now use the signed crosswalks and sidewalks within the roundabout instead of the temporary crossing at Colorado Avenue, Riddile said.

Once the project is complete, the roundabout will feature two lanes running north and south on Highway 133, and one lane exiting and entering from Main Street on either side.

The Colorado Avenue closure will also mean no access to the park-and-ride lot from the highway. However, commuters can access the lot via Colorado Avenue from Eighth or 12th streets. The temporary Roaring Fork Transportation Authority bus stop on Colorado will also move back to the East Main Street stop near the Subway sandwich shop.

In addition, paving operations are scheduled to begin this week along the 2-mile stretch of Highway 133 from Roaring Fork High School at the south end of town to Cowen Drive. This should continue for approximately two to three weeks, Riddile said.

Paving work south of Main Street will direct traffic into an alternating, one-way pattern. A lane shift will be in effect when paving is on the north end of Highway 133, between Cowen and Main, he explained.

The road will remain open to highway traffic during the ongoing construction. However, motorists should plan extra time into their travels as delays can be expected, he said.

Construction on the $9.4 million Highway 133 project began May 27, and is scheduled to be completed sometime in November.

Normal construction hours are 7 a.m. to 7 p.m. Monday through Friday. Scheduled work is dependent on weather and workload.
