47th and York Bicycle and Pedestrian Bridge

The City and County of Denver (CCD) hired Wilson & Company for preliminary design and environmental clearance of a pedestrian and bicycle crossing over the Union Pacific Railroad (UPRR) tracks near the intersection of 47th Avenue and York Street. The project provided a critical grade-separated connection over the UPRR, connecting the Elyria and Swansea neighborhoods and providing a safe, efficient connection for school children to walk and bike to and from Swansea Elementary School.  The design builds off community input and the preferred alternative outlined in the East/West Connectivity Study that was carried out in 2016. The initial bridge alignment concept was further developed. The bridge structure was located as far north as possible, putting stairs and unique triangle-shaped ramps on the east side of the bridge closer to the 47th Avenue and York Street intersection. The ramp structure type maximizes the available space within the constrained Right-Of-Way available.  The results make access to the bridge for pedestrians and bicyclists very direct and easy to utilize, while also maximizing the amount of usable land on the southeast side for public space. The project team led further community outreach resulting in creative railing, selection of colors, the addition of a local artist, a functional plaza area, and safety features such as enhanced lighting and visibility.

Wilson & Company prepared construction documents to provide a safer pedestrian route crossing the UPRR tracks. Prior to the improvements, pedestrians would cross the three tracks at random locations where locomotives operate under remote control and cannot brake immediately. The improvements consolidated the pedestrian crossing to the vehicular crossing for safe travel over the tracks. The design provides Americans with Disabilities Act (ADA) ramps, sidewalk improvements, drainage improvements, fencing, coordination and agreements with the UPRR, and includes Local Agency project clearances through CDOT. The project was completed in 2020.
