Project Description

The County of Henrico will be constructing accommodations to increase bicycle and pedestrian safety and connectivity. The following improvements will be constructed, including:

  • Re-paving and re-striping Dumbarton Road from Staples Mill Road to Brook Road to implement a “road diet”. The new roadway will include buffered bicycle lanes, one vehicle travel lane in each direction, and a right/left center turn lane.
  • Upgrade traffic signals at Byrdhill Road, Impala Road, and Hermitage Road/Westlake Avenue to install new signal cabinets, poles, signal heads, bicycle accommodations, and pedestrian push buttons.
  • Evaluate future locations for pedestrian crosswalks along Dumbarton Road between Byrdhill Road and Lakeside Avenue.

Estimated Schedule

  • Design is complete.
  • Right-of-way acquisition is not anticipated.
  • Utility relocations are not anticipated.
  • Advertisement for construction is not anticipated.
  • Construction is anticipated 2nd Quarter, 2025.

    • Traffic signal site preparation completed in June 2025.

    • Pavement rehabilitation completed in October 2025.

    • Re-surfacing/Restriping completed in November 2025.

    • Signal installation at the Byrdhill Road, Impala Drive, and Hermitage Road/Westlake Avenue intersections completed in March 2026.

Progress to Date

Initial construction on new traffic signals at the intersections of Byrdhill Road, Impala Road, and Hermitage Road/Westlake Avenue is anticipated in to begin in April/May. Expect minor delays as contractors install conduit and prepare signal pole foundations. Resurfacing and re-striping is anticipated in November (weather depending), and traffic signal installation is anticipated to be completed in December.  

  • Virtual public information meeting and online comment period from February 21 through March 13, 2022. Below is a link to the public feedback summary.

The preferred concept is planned for implementation during spring 2025 coinciding with a full repaving of Dumbarton Road. A buffered bike lane will be striped on both sides of the roadway along with a right/left center turn lane.
