Due to negative community feedback, striping changes to West 6th Avenue between Kohl Street and US 287 will not be made, and parking will not be removed at this time. Striping will be implemented on West 6th Avenue between Kohl Street to Daphne Street without parking removal later this spring. Read the full outcome under the “Project Updates” tab.


The City and County of Broomfield (CCOB) considered striping West 6th Avenue to include bike lanes and narrow lanes to reduce vehicle speeds. The latest project updates can be found under the “Project Updates” tab below.

Project Summary

The City and County of Broomfield (CCOB) considered a traffic mitigation and striping project along West 6th Avenue between Highway US 287 and Daphne Street.

The project sought to address neighborhood concerns regarding vehicular speeding by implementing striping changes that would visually narrow vehicle lanes and add bike lanes as identified in the 2019 Bicycle and Pedestrian Assessment. Restriping streets is a low-cost form of traffic calming that can help slow speeds. Anticipated construction impact would have been minimal and no road closures were expected.

Speed Reduction Interventions

Over the past 20 years, various speed control measures have been attempted on West 6th Avenue, including entry islands, striped parking areas, speed radar signs, and, most recently, flex posts. However, speeding issues still persist, as voiced by concerned neighborhood residents and evidenced in collected traffic data. This striping project would implement another speed reduction tool, while also providing a multimodal benefit.

West 6th Avenue: US 287 to Kohl Street

As part of the project evaluation, CCOB completed a parking study indicating that parking within the public right of way is not highly utilized in the section of West 6th Avenue between US 287 and Kohl Street (under 20%).

To accommodate all modes of transportation and address neighborhood speeding concerns, parking on the north side of 6th Avenue between US 287 and Kohl Street was proposed to be removed, and a bike lane installed. Parking would remain on the south side of West 6th Avenue in this section, with a new bike lane installed. An image from the cross-section showing the proposed striping is below.

A cross section of West 6th Avenue from north to south shows a five foot bike lane, a ten foot travel lane, a double yellow line, a ten foot travel lane, a six foot bike lane and a five foot parking lane.

West 6th Avenue: Kohl Street to Daphne Street

On West 6th Avenue from Kohl Street to Daphne Street, parking would remain on both sides of the roadway because driveways are distributed equally on both sides of West 6th Avenue, with parking utilization closer to 50%.

With this configuration, a bike lane would be installed uphill in the eastbound direction. Downhill, in the westbound direction, shared roadway markings would be planned, indicating the safest place to ride for bicyclists.

Public Engagement Summary

In early 2025, 265 community members completed a three-question pulse survey to share their sentiment and comments about the proposed speed reduction striping. Responses were received from residents who live on 6th Avenue between US 287 and Kohl Street, residents who frequently travel down 6th Avenue and community members who don’t regularly use the street. Due to general negative feedback from all three groups, striping changes will not be implemented on West 6th Avenue between Kohl Street and US 287 at this time. Striping without parking removal will be added to West 6th Avenue between Kohl Street and Daphne Street. You can find more information about community feedback under the “Project Updates” tab.

    Thank you for your comment. A summary document titled,  West 6th Avenue Traffic Mitigation Alternatives Selection Summary has been posted with additional background on the process. In the summary document, additional information can be found regarding the challenges of installing speed bumps (“speed cushions”) along this section of road. 

    Parking counts showed that parking along the south side of W 6th Ave from US 287 to Daphne Street was utilized under 21% at all times of day, meaning that approximately 80% of on-street parking was available. On average, there were four cars parked along the north side of this section of roadway at the times this data was collected. Based on the parking utilization data collected, the availability of parking on the south side can accommodate the parking needs of W. 6th Ave.

    This project is in addition to the Midway Boulevard project. The City and County of Broomfield received positive feedback from the bicycling community that trails are desirable, but often they do not take people directly to the destinations they would like to go to. On-street network improvements complement the trail network and provide Broomfield bicyclists with direct options to destinations. Both Midway Blvd. and W. 6th Ave. were identified for improvements in the 2019 Bicycle and Pedestrian Assessment to improve the arterial and low-stress street network connectivity for bicycling.

    While speeding has not been identified as a concern on Kohl Street, the 2019 Broomfield Bicycle and Pedestrian Assessment has identified Kohl Street as a top priority route to improve with bike lanes. Striping plans are being developed; however, implementation is dependent on funding.

    Speed cushions can help reduce vehicle speeds. Broomfield looked into installing speed bumps on West 6th Avenue. 

    To effectively reduce speeds along the corridor, 3 to 4 installations of speed cushions are needed to mitigate speeds on West 6th Avenue. The corridor was evaluated for locations to install 3 or 4 speed cushions at required intervals. Due to driveway density, it makes speed cushions a less appealing alternative, due to resident impact backing out of driveways. 

    Other alternatives to narrowing travel lanes and adding bike lanes were evaluated and determined to both reduce travel speeds and improve the network more significantly.

    Community feedback from the 2019 Broomfield Bicycle and Pedestrian Assessment showed that residents wanted better bike routes that connect to key destinations (#1), more bike routes that avoid busy roads (#3), and additional bike lanes on streets (#5) to improve cycling in Broomfield. 

    West 6th Avenue was highlighted as a route to improve bicycle connections, serving as an alternative to the busier Midway Boulevard. Traffic on Midway Boulevard ranges from 14,000 to 24,800 vehicles per day, while West 6th Avenue sees only 600 to 1,700 vehicles daily. Visit the Traffic Engineering webpage to find Broomfield traffic count data.

    Feedback also came from a resident in a wheelchair who supported bike lanes because they allow wheelchair users to move more comfortably in the street, away from vehicle traffic.

    John asked 3 months ago

    Thank you for this idea. Parking-protected bike lanes are a treatment some communities have implemented. This treatment can have benefits, including a feeling of comfort separating the bikes away from travel lanes when there is space available to implement. 

    A parking-protected bike lane is not feasible on W. 6th Ave. as it does not have the space curb-to-curb to implement a safe width for a parking-protected bike lane, retaining two-way travel lanes and parking on one side of the street. The minimum recommended width is 5’ bike lane (7’ optimal)  with a 3’ minimum buffer (4’ optimal) for the door zone for a total of 8’ minimum or 11’ optimally.

    The proposal is to retain parking on one side and install bike lanes in both directions, with the space available curb-to-curb.
