West Quincy Avenue (South Swadley Court to South Simms St)

Posted on September 4, 2019 at 3:23 PM by Lindsay Townsend

Project Scope:
This project is being designed and constructed with Jefferson County One-Half Cent Sales Tax Funds, and in part with the County’s Impact Fee Funds. The purpose of the project is to advance the design of West Quincy Avenue from West Tufts Avenue to South Simms Street from the conceptual level design to a final design for making roadway and landscaping improvements.

Planned Project Improvements/Elements:
• 11-foot wide travel lanes (one in each direction)
• Raised medians (west of Arbutus)
• Two-way painted left-turn lanes (east of Arbutus)
• 6-foot wide concrete sidewalks (attached and detached)
• 4-foot wide on-street bike lanes
• Enhanced pedestrian/bicycle crossings at:
     Regional Trail Crossing at Eldridge
     Youngfield Street bus stop
     Harriman Ditch Trail Crossing
• New storm sewer system to reduce flood potential
• Water quality treatment of initial storm waters
• Changing Quincy/Simms roundabout to a single-lane roundabout
• Changing Simms/Nassau roundabout to a single-lane roundabout
• New retaining walls
• Irrigated (low water usage) landscaping improvements

Project Update (as of September 4, 2019):
Jefferson County selected American Civil Constructors, LLC (ACC) to construct the Quincy Phase 1 construction project (i.e. S. Swadley Court to S. Simms Street).  Construction started April 15th and will continue through the fall.

ACC and Jefferson County worked this past month to devise a plan to complete Phase I of the W. Quincy Avenue Improvements project while limiting the impact to the traveling public.  This new approach will assure two lanes of through traffic (one lane in each direction).  Construction will continue into October.

Traffic Impacts:
  • ACC will maintain two lanes of traffic but will be regularly shifting them in order to perform construction activities.   
  • Larger vehicles are encouraged to take alternative routes due to narrow lanes and traffic control devices. 
  • Reduced speed through the cone zone will be enforced 24 hours a day, 7 days a week for the safety of the contractors, travelers and to protect vehicles from damage.  Cyclists are discouraged from traveling through the work zone.
  • Contractors will be on-site Monday through Friday from 7:00 a.m. to 7:00 p.m. with occasional weekend work.

The public is encouraged to use alternative routes during construction.

Note: The current traffic control during construction is a four-way stop condition.  After construction is completed, the intersection will be a new single-lane Modern Roundabout (i.e. with no stop signs).

The improvements to W. Quincy Ave. (S. Simms Street to W. Tufts Avenue) will be addressed in three phases with three separate construction contracts extending into 2024.  Phase I, ACC’s contract, is scheduled for completion this fall and involves the reconstruction of the roundabout at S. Simms Street to S. Swadley Court. 
Project Schedule: 
Phase 1 Roadway Construction (Swadley to Simms) – 2019
Phase 2 Roadway Construction (Beech to Swadley) – 2021 & 2022
Phase 1 Landscaping Construction (Arbutus to Simms) – 2023
Phase 3 Roadway Construction (Tufts to Beech) – 2023
