Project Overview

The 30th and Colorado Corridors Study looked at existing and future travel conditions and needs to develop design options to improve travel for all modes along 30th Street (Baseline Road to Pearl Street) and Colorado Avenue (Foothills Parkway to Broadway/Euclid).

Summer 2022 Info Session

A virtual information session was held on July 20th, 2022 to share more about the transportation projects being constructed as part of the 30th and Colorado Corridors Study. A recording of the information session can be found above. The information session covered the following projects:

Vision Statement

The 30th Street and Colorado Avenue corridors provide safe, enjoyable, and direct travel for people of all ages and abilities, using all modes of transportation in all weather conditions. As Complete Streets, these vibrant corridors efficiently connect people to neighborhoods, jobs, shopping, parks, schools, the University of Colorado, and the surrounding natural environment.

The City of Boulder and University of Colorado Boulder Transportation Master Plans identified the need for detailed studies of several transportation corridors in Boulder, including 30th Street and Colorado Avenue. These corridors provide travel options between key activity centers in Boulder, including the University of Colorado Boulder housing at Williams Village, CU East Campus, Boulder Junction, 29th Street and CU Main Campus.

The study area contains six of the top crash locations in Boulder, according to the 2016 Boulder Safe Streets Report.

The purpose of the study was to examine existing and anticipated transportation conditions and needs, and develop designs to improve travel for all modes for 30th Street from Baseline Road to Pearl Street, and Colorado Avenue from Foothills Parkway to CU Main Campus/ Broadway and Euclid Avenue.

The study began in 2017 and following community engagement was approved by City Council in 2019.
