The NH 3A and Dunklee Road intersection previously existed as an unsignalized ‘T’ intersection that required operators of tractor-trailers to drive in the oncoming lane when turning right onto NH 3A—an unsafe condition. Located in an industrial/commercial context, NH 3A is frequently used to bypass a tolled section of I-93 near the I-93/I-98/NH-3A junction. Working…
The goal of the Crescent Connector project was to provide a bypass of the congested Five Corners intersection for south-to-east travelers. The project included complete streets enhancements, parking, an 850-ft segment of new roadway, and 500 ft of roadway enhancement around the east side of Five Corners. D&K served as the lead consultant, designing the…
Located in the downtown core, adjacent to the Village Green, the Fair Haven Park and Ride lot consisted of lightly marked spaces with no separation from the roadway on either side. The large contiguous area of paved surface, lack of pedestrian facilities, and minimal striping provided a low level of service. Frequently used by residents…
NHDAS and the NH Legislature relied on a deteriorating parking structure to serve legislative sessions and other government needs. The NH State Government required a new 409-slip garage across the street from the State House on a site then occupied by the NH Department of Justice (DOJ) building. The DOJ was relocated within the City…

As a demonstration of this issue, the town opened the front and rear doors of the adjacent town offices during a large storm event…
Heavy rainfall and substantial snowmelt from a storm event combined with insufficient drainage systems to wash out 2,800 LF of a vital roadway crossing a mountain. The steep and winding road serves approximately 1,400 vehicles per day and connects VT 100 and VT 12. The Town of Rochester applied for and received FHWA-ER funding to…
To efficiently manage the design of highway surfacing and appurtenant systems, the Vermont Agency of Transportation (VTrans) engages consultants to supplement in-house engineering, environmental, and surveying services. Since 1998, D&K has provided design for state and US highways, including interstates, urban Class 1 sections of US or state highways, major and minor arterials, and rural…
VT 116/VT 17—with segments known locally as Main Street, East Street, and Stony Hill Road—serves Bristol Village, connecting shops, restaurants, institutions, public places, and homes. Flanked by diagonal parking spaces, sidewalks, and green spaces, VT 116 is the site of much of the village’s identity and carries a high volume of bicycle, pedestrian, and vehicle…
