Project Background

The S. Glebe & 9th Street S. Intersection Improvement project will deliver multimodal safety improvements at the intersection of S. Glebe Road and 9th Street S. This project originated through the Master Transportation Plan, community-reported transportation safety concerns, crash data, and the results of the Vision Zero High Injury Network Safety Audit of Glebe Road.

Project Goals

  • Improve the intersection of Glebe Road and 9th Street S for people walking, taking transit, biking, and driving
  • Provide better safety and connectivity for people walking and biking by improving crossings
  • Allow controlled access to and from 9th Street S by signalizing the intersection, consistent with recommendation from the 2022 Safety Audit of the Glebe Road corridor

Additionally, public input will help identify other issues present in the corridor that can be addressed by the project.

Project Basis

Planning guidance from this project comes from the following County Board-adopted plans and policies

Master Transportation Plan

  • Streets Element: The Complete Street policy informs the scope of this project to improve safety for all road users
  • Bike Element: 9th Street S. is part of the Columbia Pike Bike Boulevards, intended to provide an enhanced on-street bicycle route parallel to Columbia Pike.

Vision Zero

Vision Zero policies call on County Transportation staff to take a proactive approach to safety to eliminate severe and fatal crashes from our transportation network by 2030.

  • High Injury Network Corridor: Glebe Road from 14th Street N to Columbia Pike is part of Arlington County’s High Injury Network. These corridors experienced high concentrations of critical crashes compared to other corridors in Arlington.
  • A 2022 safety audit for the corridor found the following:
    • Speeds exceed 5MPH over the speed limit between 8th Street S. and 9th Street S.
    • 2 pedestrian crashes in a three-year period and 5 left turn vehicle crashes (Jan 2018 – Feb 2021) at Glebe Road and 9th Street S.
    • Community feedback received as part of the Vision Zero Action Plan development identified Glebe Road and 9th Street S. as an unsafe crossing
    • Recommendation: Evaluate Glebe Road and 9th Street S. for a traffic signal
