West Swanzey Visual Preference Survey and Results Swanzey NH 10 Corridor Study, 2021 2 | P a g e Introduction New Hampshire Route 10 (NH 10) is an important State highway presently carrying approximately 7,400 vehicles per day at the Winchester Town Line and 14,400 vehicles per day at the Keene Town Line with daily vehicle traffic volumes steadily increasing south to north. Many of those using the corridor are local Swanzey residents and workers, however, NH 10 is a significant regional thoroughfare as well. Beyond the 5.5 mile length of the corridor in the Town of Swanzey, the highway directly connects users to the large employment and service center, Keene, to the north, the Town of Winchester to the south, as well as many other destinations in other parts of Cheshire County, Massachusetts and beyond. Though most highway users are motorists, there is the occasional pedestrian and bicyclist. While the highway is owned and maintained by the State, and the New Hampshire Department of Transportation (NHDOT) has general performance goals to maintain a highway that gets people quickly and efficiently to their destination, is safe, and is in a good state of repair, effective corridor management cannot happen in a vacuum. Local governments like the Town of Swanzey are responsible for guiding development and permitting the activities accessing the highway from local driveways and local street networks connected to the highway. Both the State and Town have a responsibility to ensure the highway is meeting corridor user needs whether it’s a The State of New Hampshire business owner adjacent to the highway, a freight operator recognizes NH 10 as a Tier 2 highway or “Statewide Corridor” – - designed to making deliveries, a work commuter, or a resident that provide a level of mobility just below lives in a neighborhood near the highway. Developing a interstate highways and other limited common understanding about corridor related issues and access highways. needs provides a basis for the Town, State and other relevant partners to have a similar frame of reference for coordination and communication. The Swanzey NH Route 10 Corridor Study (Study) was undertaken in 2020 and 2021 by Southwest Region Planning Commission (SWRPC) with support from a Town of Swanzey appointed Working Group with a goal to better understand the corridor including opportunities for improvements and challenges to proactively address. In the following report, the Study puts the NH 10 corridor under a microscope to ask the following big questions: • How is the corridor used today and who is using (living, working, shopping, and traveling through) the corridor? • Is the corridor meeting the needs and expectations of stakeholders today? Using available trend data and information, what is the direction and outlook for the corridor and is this in line with these needs and expectations? • Based on these findings, what recommendations does the Swanzey NH Route 10 Corridor Working Group have for future management of the corridor? Swanzey NH 10 Corridor Study, 2021 3 | P a g e Corridor Use Today In this section, the report starts by asking “How is the corridor used today and who is using (living, working, shopping, and traveling through) the corridor? To answer these questions, we look at motorized and non-motorized transportation use of the corridor, characteristics of the population using the corridor, zoning and land use conditions for guiding development and permitting land use activities, and the state of economic development and housing on the corridor. Transportation Motorized Transportation Infrastructure and Trends Most people using NH 10 in Swanzey drive on the highway, although there is a small fraction of people that walk and ride bicycles along the highway as well. Daily vehicle traffic is an average of 14,400 vehicles per day at the Keene and Swanzey town line and 7,400 vehicles per day at the Winchester and Swanzey town line. Traffic volumes increase incrementally from south to north. Indeed NH 10 is designed for moving vehicle traffic. The Federal Highway Administration considers NH 10 a minor arterial highway, meaning that it is designed to link larger cities and towns and be part of an integrated network that provides intercounty and interstate service.1 NHDOT considers NH 10 a Tier 2 highway meaning that is intended for moderate to high motor vehicle traffic volumes.2 From Keene to Winchester, NH 10 is a two-lane rural highway with vehicle lanes ranging from 11 feet to 12 feet wide and shoulders ranging from 1 foot to 10 feet wide. Passing areas exist on the stretch of highway but there are no passing lanes. There are a number of dedicated left-turn and right-turn lanes to several minor streets along the highway, as well as a stretch of two-way left- turn lanes between California Street and Cobble Hill Road in West Swanzey.3 The passing areas and dedicated turning lanes are designed to keep traffic moving and reduce vehicle conflicts. All interconnecting roadways along the NH 10 Corridor carry low volumes of traffic. The highest traffic volume of any intersecting roadway is at Base Hill Road averaging 2,900 vehicles per day. California/Main Street carries approximately 1,900 vehicles per day and Ash Hill Road approximately 1,100 vehicles per day. All other intersecting roads carry less than 1,000 vehicles per day. Base Hill Road represents the only roadway that connects NH 10 directly to another arterial highway (NH 9). All other roads serve mostly local traffic and occasionally regional traffic. The gravitational effect of the City of Keene as a regional employment and service center has many people living on the intersecting roadways traveling back and forth from the Keene area, resulting in higher traffic volumes on NH 10 the closer
