Lakewood is launching a pilot project to evaluate ways to address speeding along the streets with higher traffic volumes in neighborhoods, and the first section of roadway to be evaluated is West Mississippi Avenue from Pierce Street to Sheridan Boulevard. The city is installing semi-permanent safety items to test their effectiveness, and we need your feedback.

Please participate in this project in the following ways:

About this project

This segment from Pierce to Sheridan has been chosen because it has a higher number of crashes than similar roadways (see crash information). It’s also a segment where people are walking or cycling, making it important to prevent serious crashes involving these nonmotorized users of the transportation system. This segment has also received a number of complaints from residents about speeding.

The pilot project involves installing speed cushions, median islands and pedestrian and bicycling crossings in various sections between Pierce and Sheridan. The speed cushions will include wheel slots to allow West Metro Fire vehicles to travel through without having to slow down significantly, resulting in minimal impact to the fire response. West Metro Fire has reviewed and approved the design for this pilot project. The tire slots, however, don’t work for standard vehicles, and drivers will have to slow to travel over the speed cushions.

Once these items are fully installed, the city will evaluate their effectiveness based on changes in driver behavior, feedback and analysis of any crashes. The results of this analysis will be posted here on the project’s webpage when they are available.

    Thanks for your interest in this project. The project resulted from several discussions on traffic calming with the City Council in study sessions. As a result, staff refined a proposal for a project through additional discussions including with West Metro Fire Rescue, and staff selected the road segment for the project based on data as well as the design and budget for the project. Under Lakewood's Council-Manager form of government, this is how projects progress. City Council sets the policy and direction for what it wants accomplished, and staff then executes a project or program to accomplish the direction provided by City Council.

    Kind regards,

    The Project Team

    The next locations haven't been determined, and work is underway for prioritizing locations for 2027. In looking at the draft High Injury Network, West14th Avenue is rated fourth in Lakewood. We will combine the crashes with measured speeds over the posted speed limit to arrive at a final priority list for 2027.

    Thanks for your interest in this project. You can find information about requesting a speed hump on your street on the city's website. Currently, street humps are paused on local neighborhood streets as we redirect efforts and funding this year to collector streets for traffic calming. The results of this current traffic calming effort on these larger streets will help determine future traffic calming funding. 

    Kind regards,

    The Project Team
