ROANOKE COUNTY, Va. (WFXR) – Construction is continuing near the Route 419/220 interchange, around the Tanglewood Mall vicinity, in Roanoke County.
One of the highlights of the final plan is to replace the existing interchange with a diverging diamond interchange (DDI) which, VDOT says, will provide enhanced safety, capacity and efficiency.
A virtual meeting will take place on Tuesday, June 29 between 5 and 7 p.m. to discuss the interchange. If you would like to take part in the meeting, click here to register.
Other aspects of the project include modifying three signalized intersections along Route 419 (Electric Road) with thru-cuts and signal phase reductions.
A thru-cut intersection redirects side-street traffic to turn either left or right at the signal and turn directly into businesses or to use a nearby crossover to make a U-turn.
Less than one percent of traffic that uses the intersection would be redirected.
The three intersections around Route 419 to be modified include Ogden Road, Elm View Road and South Peak Boulevard.
VDOT says that modifying these intersections will increase traffic flow and will create shorter wait times along the Route 419 corridor by reducing signal phases.
According to VDOT, crashes will be reduced by approximately 15-20 percent after the changes are made to these areas.
There are approximately 40,000 vehicles that travel through this area each day with Route 220 serving 52,000 vehicles per day.
There are five assets to this project:
- Improves safety: Compared to a conventional diamond interchange, the DDI will reduce vehicle-to-vehicle conflict points, which decreases the potential for crashes.
- Improves mobility: The installation of a high efficiency, high capacity interchange, coupled with upstream intersection improvements, will significantly reduce congestion along the corridor.
- Creates shorter wait times: Reduces the number of signal phases at intersections.
- Reduced Right of Way Impacts: The configuration of the DDI allows it to be built mostly within existing Right of Way, reducing impact to property owners along the corridor.
- Enhances Pedestrian Safety: Adds new crosswalks, sidewalks, and other features.
The DDI is expected to begin in early 2024 with a completion date in late 2026 at an estimated cost of $17.5 million.
