Diverging Diamond Interchange Meetings Scheduled
New interchange at I-66 and Route 15 opening early
HAYMARKET – The Virginia Department of Transportation invites local residents and drivers to attend one of two upcoming meetings to learn about the opening of northern Virginia’s first Diverging Diamond Interchange (DDI) at Interstate 66 and Route 15.
Wednesday, Dec. 7 and Tuesday, Dec.13 – Bull Run Middle School cafeteria, 6308 Catharpin Road, Gainesville, VA. Both meetings start at 6:30 p.m. and feature a brief presentation at 7 p.m. and an interactive DDI walk-through.
Although construction on the overall project is ongoing until summer 2017, the new DDI alignment is scheduled to open on Saturday, Dec. 17, weather permitting. The interchange will be closed the night before for final lane striping.
The DDI’s innovative design shifts vehicles to the opposite side of the road and eliminates left turns that cross oncoming traffic. Two-phase traffic signals at each end of the interchange reduce time spent at red lights and move twice the number of vehicles as a traditional diamond interchange. VDOT recently completed its first DDI in Louisa, and has two more in the works in Blacksburg and Stafford.
