July 2025: Public Works Announces Niwot Road Median Closure Near Diagonal Highway

Boulder County Public Works announces a temporary median closure on Niwot Road near the CO-119 Diagonal Highway intersection for utility infrastructure improvements. The closure will affect left turns from Niwot Road onto the Diagonal Highway for approximately six weeks. A signed detour route will be in place.

The Anne U. White open space property encompasses 1,049 acres and features 12 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

According to Rachel Stein, director of Assessor’s Office, this program served 54% more residents in 2026 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Superior and the surrounding area,” Rachel Stein said.

Eligibility

The Superior Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,265 seniors participated in center programs last year.

Data from the 2026 Boulder County Community Survey shows that 54% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 6,302 responses from residents across the county.

Timeline

The Assessor’s Office processed over 5,193 applications last year, with an average processing time of 3 business days. Staff are available at the Superior office Monday through Friday from 8:00 AM to 4:30 PM.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Superior and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.
