New Hampshire Route 175 - Route Description

Route Description

NH 175 begins at an intersection with US 3 and NH 25 (Daniel Webster Highway) at Little Squam Lake in the town of Holderness. The state highway heads north and then west through a hilly area where it briefly passes through the town of Ashland before returning to Holderness. NH 175 enters the valley of the Pemigewasset River and passes by the historic Trinity Church and near the Holderness School and the Chapel of the Holy Cross. North of the school and churches, the highway meets the eastern end of its spur into Plymouth and Plymouth State University, NH 175A. NH 175 continues north parallel to the river and I-93 and US 3, which follow the opposite, right bank of the river, into the town of Campton. The highway crosses the Beebe River and parallels the Mad River to its bridge over the river immediately to the south of the highway's junction with NH 49. NH 175 passes through the town of Thornton and its name becomes Eastside Road on entering the town of Woodstock. The highway passes under I-93, has two crossings of the Pemigewasset River, and intersects Tripoli Road, which has a diamond interchange with I-93 immediately to the east. NH 175 has an oblique grade crossing of the Hobo Railroad before crossing the river a third time on a truss bridge and reaching its northern terminus at US 3 (Daniel Webster Highway) just south of the community of North Woodstock.
