Project Description

This project will widen and improve the Ralston Road corridor between Upham and Yukon Streets (Phase One-complete) followed by the segment between Yukon and Garrison Streets (Phase Two-in progress). 

Ralston Road is an arterial road and a major east-west corridor for Arvada, serving 23,000 vehicle trips each day. It provides connectivity to major north-south corridors and serves five the Regional Transportation District (RTD) bus lines.


  • 8-foot wide pedestrian path (similar to a trail). providing access to parks and trails. This sidewalk width exceeds ADA minimum, allows pedestrians to walk side-by-side or with their pets and creates distance from the travel lanes.
  • Widen the existing 9 foot vehicle travel lanes to 11 feet to help decrease sideswipe accidents.
  • Installation of gutter pans to provide an additional 1 foot of space for the accumulation of rain, snow, and debris outside of the travel lanes.
  • Widen the center two-way-left-turn lane to 12 feet to increase driver safety/comfort while stopped between passing vehicles.
  • Reconstruction of aging traffic signals with new technology to improve traffic progression.  

What to Expect During Construction

  • Access to all businesses along Ralston Rd is open during construction.
  • RTD service along Ralston Road will continue during construction.
  • There will be lane closures and periodic closures of roads that cross Ralston Road.
  • Construction will be conducted in stages in order to efficiently use resources. It may appear that construction moves around or stops and starts in certain areas.  
  • There will be disruptions to your typical travel on Ralston Road. We encourage all residents to consider alternate routes and plan for additional travel time.
