Draft Purpose and Need Purpose: The Town of Manchester wants to identify options, potential impacts, and costs associated with the development of multi-use path along the abandoned MD&G Railroad corridor. Need: There has been an informal path along the rail corridor and there has been expressed interest in formalizing the trail and creating a public amenity for locals and visitors.

Right-of- 2000 Conceptual Local Way and Feasibility Path from Citizens This Study Funding Study along MEMS to Purchase and Design Delayed Rail Corridor North Road Rail Corridor Project

Project Context  Create additional bicycle and pedestrian connectionS in Manchester  Add approximately 1.6 mile multi-use trail along the old railroad corridor  Extend from Riley Rink at Hunter Park and extend northerly to North Road (Across from Squires Road Intersection)

1.6 Miles of New Trail Private Property Stream Crossing Beattie Lane Riley Rink

Existing Conditions  Natural Resources  Flood Hazard Zone  Wetlands, River Corridor at Streams  Cultural Resources previously identified along the corridor

Stream Crossing #1  Between Mt. Aeolus Lane & Beattie Lane  Intermittent Stream  Existing Stone and Wood Structure Replaced by Corrugated Plastic Culvert

Stream Crossing #1 Improvement Recommendations Add more fill to cover the inlet and outlet of the 1. culvert, which are exposed. Add stone fill to armor the inlet and outlet to 2. prevent erosion and scour. Lay down gravel on the trail to improve the walking 3. surface. Estimated Cost: $2,500

Stream Crossing #2  Southeast of Beattie Lane  Perennial Stream  Existing Bridge Mostly Deteriorated  Potential Long Span Bridge

Stream Crossing #3  North of Field  Perennial Stream  Existing Bridge Mostly Deteriorated  Potential Long Span Bridge

Stream Crossings #2 & #3 Alternatives A, B, & C Alternative A: Alternative B: Alternative C: Steel or Steel Girder Bridge Concrete Arch Aluminum Plate Arch Pros: Pros: Pros: Construction would be out • Low maintenance • Least expensive option • of channel requirements leading to Cons: Matches existing bridge • longer service life Shorter service life than • south of Riley Rink Cons: concrete arch due to Cons: Most expensive option • corrosion and abrasion Has greater maintenance • requirements

Stream Crossings #2 & #3 Alternatives D & E Alternative D: Prefabricated Timber Bridge Pros: Reasonable cost for a unique look • Cons: Timber typically has a shorter service • life than concrete or steel Alternative E: Prefabricated Steel Truss Bridge Pros: Easy to install • Cons: Similar maintenance requirements • to girder bridge
