High Line park and commercial spillover (2009)
New York City opened the first section of the High Line, a 1.45-mile elevated rail line converted into a linear park on Manhattan's West Side. It attracted millions of visitors and sparked a boom in adjacent real estate and retail.
Property values along the route rose sharply; new hotels, galleries, and restaurants opened.
The High Line became a template for rail-to-trail projects worldwide, showing that greenways can generate commercial energy—sometimes too much, as critics noted rising rents displaced longtime tenants.
The High Line demonstrates the potential economic ripple of trail corridors. Salt Lake's 9 Line is far smaller, but the Wall Cafe's bike-up window is an early signal of the same commercial adaptation to active-transportation infrastructure.
