VDOT completed construction of the Opal interchange flyover on Dec. 13, 2013. Some southbound Route 29 traffic continues to turn onto Route 17 south at the signal rather than using the flyover, causing a long queue in the left-turn lane and spillover into the through lanes.
Since early 2014, VDOT has been taking steps to improve traffic flow and, most importantly, safety at the intersection. These include:
• Adding and revising the wording of signs to better reflect the traffic pattern
• Adjusting traffic signal timing/phasing
• Installing improved pavement markings
• Reaching out to GPS providers to include the flyover on their map updates
• Working with the trucking industry to inform drivers of the new traffic pattern
• Using CB radio technology to broadcast messages to truck drivers
• Using message boards to catch motorists' attention
• Monitoring traffic flow with a portable camera and periodic traffic counts
• Ongoing public outreach
Please assist VDOT by passing on notice of the new traffic pattern.
This project will replace the current at-grade left-turn movements from Route 29 southbound onto Route 17 south with a grade-separated flyover interchange.
The project will improve safety and traffic flow at this high-volume location. The current dual left-turn lanes on Route 29 south often overflow onto the southbound travel lanes during periods of peak volume. This condition creates a safety issue since southbound through traffic traveling at highway speed must stop until the left-turning traffic clears the travel lane.
The flyover will allow traffic turning onto Route 17 south to exit Route 29 using a right exit ramp. The ramp will carry traffic over Route 29 south of the existing intersection, then allow it to merge onto Route 17.
Traffic continuing south on Route 29 will not be affected by the project but should gain efficiency through the intersection since left-turning traffic will have free-flow movement using the flyover ramp rather than being controlled by the signal.
