Ralston Road Streetscape

Ralston Road Street Project

Project Background and Description

The reconstruction of Ralston Road is an ambitious two-phase project to widen this important corridor and provide sustainable infrastructure for the area. Phase One of the project which addressed roadway, accessibility, pavement conditions, and aesthetic upgrades from Upham to Yukon Streets is completed.

Phase Two, which is funded through a voter approved bond measure, will encompass pavement reconstruction from Yukon to Garrison streets as well as widening, adding safety and drainage improvements, bringing existing curb ramps and sidewalks into ADA compliance, replacing aging traffic signals, and incorporating landscaping to create a vibrant urban streetscape.

Highlights of the project include: 

  • Relocate utilities and make drainage improvements

  • Replace aging traffic signals

  • Widen traffic lanes and add safety features

  • Install new ADA-compliant curb ramps and upgrade gutters on both sides of the roadway

  • Construct 8’ detached or 10’ attached sidewalks

  • Add landscaping to create a new urban streetscape

  • Reconstruct pavement on Ralston Road

Highlights of the project

  • Creation of 8-foot wide pedestrian path (similar to a trail), allowing cyclists access to parks and trails. This sidewalk width exceeds ADA minimums and supports the needs of Arvada’s aging population. It also 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. This will help decrease sideswipe accidents.
  • Installation of gutter pans to provide an additional 1 feet 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.
