Road right-of-way widths vary. In the early years of 'laying out' town roads, many right-of-ways were established at a width of "two rods" or 33 feet (the rod was an early form of survey measurement equal to 16.5 feet). The most common right-of-way width adopted with today's roads is 40 feet. However, depending on the road, right-of-way widths can vary up to 100 feet. Since road pavement widths also vary from 18 ft to 31 ft, and may not be centered within the right-of-way, there is no standard answer to this question. Locating existing roads or property bounds by surveying is the only correct way to determine the edge of the right-of-way. The Engineering Department does not provide this service to property owners and it is recommended that if they cannot locate existing bounds they hire a land surveyor before installing fencing, walls, or other structures within the right-of-way.
