VDOT Making Improvements to Zion Crossroads Intersection
Diverging Diamond interchange plans for I-64 and Zion Crossroad area
A construction project is slated to start next month, and it's likely to cause more traffic problems for central Virginia drivers. But the Virginia Department of Transportation says that in the long run, the innovative project will cause less backup at a busy intersection.
Starting in mid-May, VDOT is expected to start work on a nearly $6.9 million project to improve the Interstate 64 interchange in Zion Crossroads. VDOT says this project will be the first of its kind in the commonwealth.
The project will rebuild the interchange of I-64 and Route 15 into what's called a 'diverging diamond interchange' or DDI. By shifting vehicles to the opposite side of the road, the design eliminates traditional left turns that must cross over oncoming traffic.
"VDOT looked at a couple different options at this interchange and this is the one that we are able to do within the existing right of way," said Stacy Londrey, a VDOT spokesperson.
Londrey said the new interchange improves safety by reducing the number of spots where vehicles could collide, and it can handle twice the number of left-hand turns.
"This interchange is one that is busy at peak times during commuting and as the area develops more and more, we're going to see more traffic here. The project is able to use the existing bridges and existing right of ways, so it's a pretty low-cost project in the scheme of things," Londrey said.
At least one lane of traffic will remain open in both directions on Route 15 during construction.
Traffic is expected switch to the new diverging diamond pattern this winter, with construction expected to be fully completed by late spring of 2014.
VDOT is hosting an open house informational meeting about the project on Wednesday, May 1. It takes place from 4:30 p.m. to 7 p.m. at the Best Western Plus in Zion Crossroads.
Virginia Department of Transportation Press Release
CULPEPER — Next month the Virginia Department of Transportation will start work on a $6.88 million project to improve the Interstate 64 interchange at Zion Crossroads in Louisa County.
The project will rebuild the interchange of I-64 and Route 15 as a diverging diamond interchange (DDI). By shifting vehicles to the opposite side of the road, this innovative interchange design eliminates traditional left turns that must cross over oncoming traffic. The DDI improves safety by reducing the number of spots where vehicles could collide and can handle more than 600 left-turn movements per hour, twice the capacity of a conventional interchange.
The Zion Crossroads DDI will be the first of its kind in Virginia.
Schedule and Traffic Impacts
Construction is expected to begin in mid-May. VDOT and design-build contractor Corman Construction Inc. have committed to keeping one lane of traffic moving in both directions on Route 15. Lane closures will shift over the course of the project, so motorists are urged to drive with caution and obey all traffic signs.
This winter, traffic operations will switch from the current pattern to the new diverging diamond pattern. VDOT will provide advance notice to motorists and all other stakeholders before the switch occurs.
Construction will finish in late spring 2014.
Citizen Information Meeting
The public is invited to learn more about the DDI and its construction schedule at a citizen information meeting. The open house-style meeting will take place Wednesday, May 1, from 4:30 to 7 p.m. at the Best Western Plus, 135 Woodridge Terrace, Gordonsville, VA 22942.
Corman Construction Inc. of Colonial Heights is the contractor for this design-build project. For more information visit the Zion Crossroads Interchange project page on VDOT's website.
