In the USA and Canada, where urban sprawl has begun to strike even the most rural communities, developers and local leaders are currently striving to make their communities more conducive to non-motorized transportation through the use of less traditional paths. The Robert Wood Johnson Foundation has established the Active Living by Design program to improve the livability of communities in part through developing trails,[11] The Upper Valley Trails Alliance has done similar work on traditional trails, while the Somerville Community Path and related paths, are examples of urban initiatives. In St. John's, Newfoundland, Canada The Grand Concourse, is an integrated walkway system that has over 160 kilometers (99 mi) of footpaths which link every major park, river, pond, and green space in six municipalities.
