Certified Traffic Control, Construction Signs & Rentals - New York, Vermont, Massachusetts and Northern Pennsylvania

Founder Carrie Donnelly Speshock, grew up in and around highway construction. In 1994 she established a highway maintenance business in Mechanicville, NY. Over the past 20 years, Donnelly Construction Inc. (DCI) services have grown to accommodate the constantly changing need of our customers. Donnelly Construction Inc. is committed to our customer service and satisfaction.

Donnelly Construction started with highway mowing and landscaping contracts for both public and private customers. Donnelly Construction then expanded into transverse and longitudinal grooving of bridge decks, crack sealing, project construction signs, work zone traffic control and flagging, soil erosion, and crack sealing. Over the years, Donnelly Construction added rentals including project construction signs and stands, portable variable message signs, attenuator trucks, tack trucks, arrow boards, speed trailers, temporary concrete barrier, cones and barrels, portable traffic signals.

An exciting service addition has been an under bridge inspection unit (UBIU). What better addition to our sought after traffic control services!

Our 40 employees proudly perform on 100 different contracts a year either as a prime contractor or a subcontractor. Our headquarters are centrally located in the Capital District, Saratoga County; 5 miles from I-87 Exit 10, 11 or 12. This location makes it easy for us to service all over the state of New York, Northern NJ, Western Vermont, and Massachusetts. It is also very convenient for those who wish to pick rentals up from us to find us, and get right back on the road.
