The New York State Department of Transportation released Route 347 Phase II as a Design-Build project; the second within the Route 347 corridor in Smithtown, Long Island. Using this project delivery method, both the design and construction are contracted as one unit. This unifies the key components and entities of the project, allowing the Owner to manage one contract with a single point of responsibility. The scope of work includes:
- Reconstruction of Road – The reconstruction of Route 347 includes widening the road and repaving after a new drainage system has been installed. The eastbound and westbound sides of Route 347 will be widened, along with Terry Road, due to anticipated growth in traffic density in the Smithtown/Hauppauge area.
- Installation of Sound Walls – Sound walls are installed on both the north and south sides of Route 347 to mitigate noise from the road for community residents.
- New Drainage System – A new drainage system is installed on Terry Road and the eastbound and westbound sides. The drainage system runs into the Nissequogue River. A 3′ x 5′ culvert is included on the westbound side of Route 347 (on the western side of the river) for additional water storage.
- Shared Use Path for Pedestrian Traffic – A shared use pedestrian and bike path is added to the eastbound side of Route 347. The westbound side of the road includes a new sidewalk.
- Greenway Stop – A greenway stop is added to the eastbound side of Route 347, directly from the shared use path. It is intended to be a rest stop for pedestrians and bicyclists traveling on the shared use path. This area includes benches, a shaded canopy, solar panel lights, bike racks and informative signs.
