Route 106 Highway Improvements
The highway construction project is located in New Kent County, Virginia and is comprised of interchange modifications at the ramp termini of Interstate 64 on Virginia Route 106, interstate milepost 211. This construction is not funded with state or federal funds.
The existing diamond interchange, constructed in the early 1970's, provides full interchange movements to and from Route 106 with ramp termini controlled with stop signs. These ramps are constructed on fill and intersect Route 106 crossing over Interstate Highway 64 on a two-lane overpass. The proposed project is designed to be constructed on land acquired with the construction of the Interstate 64 interchange. Adjacent lands are wooded, with no view of any historical sites.
The proposed highway improvement consists of replacing the existing stop controlled ramp terminals on each side of the I-64 overpass with roundabouts. The roundabouts will be constructed within the existing VDOT right of way on existing fill. Additional fill has been added within the right of way to complete each roundabout. Each roundabout will remain at the existing grade of the ramp termini.
The roundabouts will eliminate stop control for off ramp traffic and will function with ramp yield control, with traffic in the roundabouts having the right of way. Each roundabout will have free right turn movements that do not enter the roundabouts. Thus, traffic traversing each roundabout is limited to through and left turning movements.
These roundabouts are modeled after an interchange in Maryland (Routes 100 and 103) and reported in FHWA's "Public Roads", Nov/Dec 2002 issue.
