The first phase of construction on the 35th Ave. and O St. roundabout moved forward Monday with approval from the Weld County Board of Commissioners to close the northbound lane of 35th Ave. north of O St. to WCR 66 (AA St.). The closure will begin on Monday, April 4, and last for the duration of the project, which is scheduled to be completed by September. The second phase of the project, which will begin in mid-July, will require the entire 35th Ave. and O St. intersection to be closed for about 45 days.

“Road construction projects and closures are never fun for residents and commuters,” said Weld County Commissioner Scott James. “But breaking this project up into two phases, will allow us to cause the least disruption possible for those who travel through the county via these routes.”

Until the project’s second phase is underway, travelers will still be able to travel east/west on O St. as well as travel south on 35th Ave. from the north (35th Ave. south of O St. will not be impacted during phase one of this project).

“To provide an opportunity for residents to learn more about this project and to ask questions, the county is hosting a public meeting this week for residents to meet the contractor,” said Commissioner Steve Moreno, coordinator for the Public Works Department.

The public is invited to the Weld County Administration Building — located at 1150 O St. in Greeley  — on Thursday, March 31, from 5:30 to 6:30 p.m., to meet with the contractor, IHC Scott, and Weld County Public Works staff. If you cannot attend the meeting, please sign up for email alerts from the county, which will keep residents and travelers informed of the project’s timeline, progress and other important information. To sign up, visit the county’s newsletter subscription page, enter an email address and select “35th and O St. Roundabout Project.”

“We’re always looking for ways to provide the safest and most efficient transportation system through our county, while at the same time using taxpayer dollars efficiently and effectively. Roundabouts have been shown to be safer options in high-traffic areas compared to a traffic signal or four-way stop, are more efficient at moving traffic through an intersection and are cheaper to maintain in the long run,” James said. “At the same time, we know this project we’ll impact many people, so it is our hope that email alerts will keep people informed and aware of what to expect when traveling near the intersection.”
