  8. Surface , width, grades Surface • Criteria • Easily navigable by all users • ADA accessible (firm & stable) • Considerations • Anticipated user volumes • Types of users • Geographic context • Types • Asphalt • Concrete • Crushed stone East Bay Bike Path- Providence, RI • Boardwalk East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  10. Surface , width, grades (cont.) Asphalt • Accessibility: preferred • Best for: cyclists (esp. commuting), walkers, skateboard/rollerbladers, strollers • Cost: moderately $ • Lifespan: 7-15 yr/avg • Maintenance: more frequent, $1,900/yr per mile • Geographic context: urban, suburban, rural • Construction Considerations: aggregate & binder, drainage, thickness, sub-grade, compaction Head of the Meadow Bike Path- Truro, MA East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  11. Surface , width, grades (cont.) Concrete • Accessibility: preferred • Best for: similar to asphalt • Cost: more $ • Lifespan: 25+ yr/avg • Maintenance: less frequent, good for flood prone areas • Geographic context: urban, suburban Harborwalk- New Bedford, MA East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  12. Surface , width, grades (cont.) Crushed Stone • Accessibility: not preferred, but if firm & stable then ADA • Best for: cyclists (rec & touring), walkers/runners, equestrians • Cost: less $ • Lifespan: 2-5 yr/avg • Maintenance: more frequent, $1,000/yr per mile • Geographic context: suburban, rural • Construction Considerations: material type, aggregate size, compaction, cross-slope, drainage Eastern Trail- Scarborough, Maine East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  13. Surface , width, grades (cont.) Boardwalk • Accessibility: not preferred (unless concrete decking) • Best for: walkers • Cost: more $ • Lifespan: 15 yr/avg for timber, 50- 75 years with concrete • Maintenance: less frequent, good for flood prone areas • Geographic context: suburban, rural • Construction Considerations: material type, railings, water clearance Quequechan River Rail Trail- Fall River, MA East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  14. Surface , width, grades (cont.) Width • Criteria • Goal 12’ • “AASHTO 5.2.1 Width” • Minimum 10’ • 11-14’ for higher user volumes • 8’ in rare circumstances • Considerations • Primary hard tread surface & parallel soft shoulders American Tobacco Trail- Durham, NC East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  15. Surface , width, grades (cont.) Grade • Criteria • “AASHTO 5.2.7 Grade” • Maximum 5% • Considerations • Sidepaths should be ≤ 5%, but can follow the grade of the adjacent roadway East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org Sea Street sidepath- Hyannis, MA

  24. Bridges Bridge design specifications: Follow AASHTO and/or NACTO guidance (minimum 8' width) • Plan for both pedestrians and bicyclists • Safety - Bypass dangerous and/or impractical at-grade crossings • Directness - Leverage demand for the shortest path, usefulness • Network necessity - Reinforce need with connectivity on each side • Impact - Flip cost into benefit: safety, economic, equity, environment • Prominence - Create iconic structures as a legacy for future generations • East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  25. Bridges, (cont.) 117 ft long 12 ft wide $1.54 mil Existing RR ROW Farmington Canal Heritage Bridge over Route 6 in Farmington, CT. East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org

  26. Bridges (cont.) Bridges vs. Crossings At-grade design solutions: • Should be prioritized instead of a bridge (where possible) • Benefits users by reducing speeds and encouraging multi-modal, sustainable transportation • Help trail users avoid climbing and descending a bridge • Particularly helpful for those with physical disabilities and issues with mobility • Formalize bike/ped crossings that would still likely occur (despite being illegal and less safe) • Cost is much less than engineered bridges • East Coast Greenway Alliance • Connecting people to places, Maine to Florida • greenway.org
