30th Street and Colorado Avenue is one of the busiest intersections in Boulder. It is an important travel corridor for the community, including the University of Colorado Boulder:
- 30,000 cars and 1,500 bicyclists and pedestrians travel through the intersection in a typical day.
- 1,300 people board and exit RTD and CU buses using the four stops at this intersection.
The intersection is a top crash location in the city:
- 86 collisions took place between 2012-2016, 18 of those involving bicyclists.
- The existing on-street bicycle facilities create a high level of stress for many bicyclists. This leads some bicyclists to ride on the sidewalk instead, which is a common cause of crashes in Boulder.
The project area is growing:
- The Boulder Valley Comprehensive Plan and the University of Colorado East Campus Master Plan forecast growth in the project area, which will result in more people traveling through this intersection.
Improvements to the area implement the 30th and Colorado Corridors Study and are an important part of the city’s Core Arterial Network (CAN). The CAN is a connected system of protected bicycle lanes, intersection enhancements, pedestrian facilities, and transit facility upgrades that will help reduce the potential for severe crashes and make it more comfortable and convenient for people to get where they need to go along Boulder’s main corridors.
Two related projects from the study will start in 2023 and 2024 and will connect to the protected intersection with new sidewalk-level protected bike lanes on 30th Street north of Colorado Avenue and on Colorado Avenue west of 30th Street.
