Overview

The City is installing a new traffic signal that includes pedestrian signals, lighting and striped crosswalks at Arapahoe Road and Clarkson Street. Currently, the nearest signalized crossings are to the west at Broadway or to the east at Franklin Street.

This project was selected for funding by the Colorado Department of Transportation (CDOT) and the Denver Regional Council of Governments (DRCOG) as part of the Safer Main Streets Initiative. In 2020, the Safer Main Streets Initiative was created to support infrastructure projects that improve safety and accessibility along urban arterials (non-freeway corridors in the Denver Metro area). This initiative focuses on vulnerable users, such as pedestrians, bikers, motorcyclists, transit users, the elderly and those with disabilities.

Project Update

Xcel has installed the transformer to power the traffic signal. Construction is anticipated to begin late 2024 or early 2025. Estimated completion is for summer 2025.

Project Location

  • New Traffic Signal Installation - The signal will be installed at the intersection of Clarkson Street and Arapahoe Road.
  • Traffic Calming - The project team received feedback on traffic calming measures on Clarkson Street between Costilla Avenue and East Panama Drive. This may include the extension of bike lane facilities on Clarkson Street which currently end at Arapahoe Road.

Project Benefits

Clarkson runs the entire length of the City from north to south and is signalized at all major arterial roadways except for at Arapahoe. Completion of this project will make it easier and safer for residents to travel north to south along Clarkson Street. Also, Clarkson Street has bike lanes and with the new signal, the bicycle infrastructure will connect to the High Line Canal Trail north of Arapahoe Road as well as a route to the C-470 trail connection just south of County Line Road.
