Countywide Bikeways Facilities should deploy durable materials appropriate to the funding source. Treatments should be designed to prioritize the safety of people biking, walking, rolling, and using transit.
For major capital projects on the Countywide Bikeways Network, streetscape elements should utilize the most durable materials possible, like concrete buffers or if possible, raised bike lanes. These buffers may include landscaping. Other projects may consider temporary, low-cost, or quick build-type buffer treatments. Designers should carefully consider maintenance and durability and prioritize successful and safe implementation. In most cases, critical design elements at bus stops and intersections should be implemented using durable, permanent materials.
Chapter 3 of the MassDOT Separated Bike Lane Planning and Design Guide provides detailed considerations on buffer materials, drainage patterns, and considerations for raised or street-grade bike lane buffer design. For intersections, Don’t Give Up on the Intersection from NACTO provides input on appropriate materials for different contexts.
