Niwot Road before shoulders and reconstruction. 

Neva/Niwot Shoulders & Roadway Reconstruction - U.S. 36 (Foothills Highway) to 63rd Street

Road Work to begin on Niwot Road between 55th and 63rd Streets
Work will begin Monday, April 29 and continue through mid-June



Boulder County will be starting construction on Niwot Road between 55th Street and 63rd Street on Monday, April 29.  Work includes removal of the existing asphalt pavement, reworking the dirt shoulders, and applying a new roadway surface including new 4-foot wide paved shoulders.

The road will remain open, but there may be lane closures and delays during paving operations. Drivers should expect unpaved road sections, uneven surfaces, paving operations and minor delays during the next six weeks. Work is expected to be completed by mid-June, though schedules are subject to change due to weather and other factors.

This work is the final segment of the Neva/Niwot Shoulders project which began last fall. When finished, the project will complete a missing link and provide continuous road shoulders from Hwy 36 to 95th Street in Niwot.

Should you have any concerns or want more detailed information please contact Andy Reed.

Neva Road and Niwot Road will be under construction between US 36 (Foothills Highway) and North 63rd Street starting July 30 and lasting through the end of November.

Boulder County is reconstructing the roadway and adding four-foot shoulders to the entire length of road. The road is expected to remain open to all traffic including cyclists for the majority of the project, however road users should expect variable road surfaces including milled asphalt and dirt-road conditions; lane closures; and significant delays until construction is complete. Some daytime road closures are anticipated.

The final design maintains the roads current alignment and two-lane configuration. Some minor realignment is needed to accommodate the increased shoulder width, reduce impacts to agricultural properties, and to minimize the need for tree removal.

Preliminary Construction Schedule

  • Segment 1 - 55th Street to Curves. Construction to begin August 1 and last through Labor Day.
  • Segment 2 - Curves to 39th Street. Construction throughout September, potential daytime closures to lower the road west of Fairways Drive in order to improve intersection visibility and safety.
  • Segment 3 - 39th Street to US 36 (Foothills Highway). Construction throughout October. 
  • Segment 4 - 63rd Street to 55th Street. Final stage of construction weather permitting.

Over the past two years, Boulder County has reconstructed the entire length of Neva Road and Niwot Road between US36 (Foothills Highway) and 63rd Street including the addition of two four-foot shoulders to the entire length of road. Final construction is underway and expected to be complete by the end of June 2013.

The project was able to maintain the historic alignment of the roadway and maintain the two-lane configuration. A bicycle pull-out area has also been added as a rest stop for this popular cycling route.

Boulder County will be providing updates on construction as the project moves forward. Please send email to address below if you'd like to be added to the email notification list.
