Niwot Park-n-Ride and bus stops at Hwy. 52 will be impacted during construction

Boulder County, Colo. - The Colorado Department of Transportation (CDOT) and Contractor, Kraemer North America, will begin construction of the Colorado Highway 119 Safety, Mobility and Bikeway Improvements Project on Monday, Sept. 23.

CDOT, the Regional Transportation District (RTD) and Boulder County are working together to mitigate increased traffic congestion, delays and crashes and expand transportation options beyond private automobiles through this project. If your usual travel route will be impacted by construction, remember to take alternate routes or use Colorado’s public transportation services for easier access to and from your final destination.

What to watch for:

As part of this work, drivers, pedestrians and cyclists may notice increased construction equipment in the area, traffic delays and lane shifts at shoulders along the corridor and intersections throughout the project duration.

RTD will temporarily close the Niwot Park-n-Ride and permanently close the north and southbound CO 119 bus stops at CO 52 beginning Sept. 29. When it reopens in May 2027, the Niwot Park-n-Ride will include platforms for the new CO 119 Bus Rapid Transit (BRT) service, a larger parking lot with lighting and security cameras, secure bike parking, and access to the newly constructed bikeway.

The northbound and southbound CO 119 bus stops at CO 52 will close Sept. 29 to facilitate reconstruction of the intersection to include new BRT bus platforms and continuation of the median for the new bikeway. Temporary stops were not warranted at this location due to lack of available ADA compliant stop locations. The next closest bus stops served by the BOLT bus are at 63rd St. to the south of CO 52 and Monarch or Niwot to the north.

Additionally, there will be lane closures at various times near the following intersections: Jay Road, CO 52, 71st Street, Niwot Road, Oxford Road, 83rd Street, and Airport and Connector roads.
