Project Update: Traffic Changes and Roundabout Opening

Construction continues on the Timnath Parkway - Buss Grove Rd. to Main St. (CR 5) Project, with crews advancing roadway improvements and preparing for upcoming traffic changes.

Traffic Updates

Timnath Parkway - Buss Grove to Main St.(CR 5) Roundabout –The newly constructed roundabout is anticipated to open to two-way traffic by end of the day on Friday, Nov. 6, weather and construction schedules permitting. This milestone will provide an important connection to Main Street Timnath.
Buss Grove Rd. and Main St. (CR 5): The intersection is expected to reopen by the end of the day on Friday, Nov. 6.
Ongoing Traffic Impacts: Motorists may encounter temporary daytime lane shifts, intermittent lane closures and flagging operations as construction continues.
Colorado Blvd.: As part of the Thornton Waterline Project, Colorado Blvd. will be fully closed north of Wildwing Dr. from Nov. 7 through Nov. 26. Motorists should plan alternate routes and allow additional travel time.

Benefits of Roundabouts

The roundabout is designed to enhance safety, improve traffic flow and strengthen connections throughout the community.

Key benefits include:

Improved Safety: Reduces the number of potential conflict points between vehicles and lowers the risk of severe crashes compared with traditional intersections.
Slower, Safer Speeds: Encourages motorists to slow down when entering and navigating the roundabout, helping create a safer environment for all roadway users.
Efficient Traffic Flow: Keeps vehicles moving through the intersection, reducing unnecessary stops, delays and congestion.
Pedestrian and Bicycle Safety: Provides designated crossing opportunities and encourages reduced vehicle speeds, improving safety once these facilities are completed and open for use.
Enhanced Connectivity: Improves connections[KM1] throughout the community, providing better access to local businesses, neighborhoods and surrounding areas.

Remaining Construction Activities

Crews will continue utility relocations, sidewalk improvements, landscaping and other remaining construction activities.

Anticipated Project Completion

Major roadway improvements are expected to be substantially complete by the end of 2026, with remaining lighting, signage and landscaping work continuing into 2027.
