Driving through New England it is evident that most roads meander around following the routes of old cow paths and other such town roads. Here in Pembroke, New Hampshire this was not the case. Both north and south of the town of Pembroke US Route 3 has the curves and bends you would expect but in Pembroke the road is linear paralleling the Merrimack River. This community planning of parallel roads was undertaken by the town in the early 1700s. Liner grid street planning well ahead of its time. The marker commemorating the plan also has a marker describing an 1884 watering trough which is still on site.
