Neighborhood Traffic Circle Pilot Project - Brooks Dr & W 59th Pl

Share on Facebook Share on Twitter Share on Linkedin Email this link

The Arvada Public Works Department is installing a temporary neighborhood traffic circle at the intersection of 59th Place, Brooks Dr and the Ralston Creek Trail. The project is being implemented to improve the safety and comfort for trail users and reduce speeding. It will be constructed initially with paint and flex posts to test the effectiveness of the traffic circle without making a large financial investment. If the traffic circle is effective and supported by the community, it will be made permanent in the future with concrete and landscaping.

The neighborhood is encouraged to provide feedback throughout the six month trial period. The community's feedback and input is essential in helping Public Works decide whether or not the traffic circle is a success.

There are several tools available on Speak Up to provide your feedback, including a discussion area, a map to provide information about other transportation issues in your neighborhood, and a survey.

What is a neighborhood traffic circle?

A traffic calming circle is a raised island located in the center of an intersection around which traffic must circulate. By providing a landscaped area in the middle of the roadway, they can visually break up the scale of wide streets, break up the monotony of the street grid, and provide space for added greenery and stormwater treatment. Traffic circles are generally used at low volume neighborhood intersections. Traffic circles can help slow traffic on local and collector streets and calm traffic for pedestrians. Traffic circles typically have less of an impact on emergency vehicles than speed humps or speed tables, and can add to the aesthetics of the street.
