Metro Opens the Rail to Rail Bike and Walk Path Through South LA

A 5.5-mile walking and biking path on an abandoned freight line along Slauson Avenue, from near the K Line's Fairview Heights station to the A Line's Slauson station, built for $166 million.

LA Metro held a rolling dedication and community fair to open the Rail to Rail Active Transportation Corridor, a 5.5-mile multi-modal path and green space through Inglewood and South Los Angeles^[1]
The path replaced unused, blighted railroad tracks and links the K Line's Fairview Heights station, the J Line's Slauson station and the A Line's Slauson station by bike and on foot^[1]
The $166 million project was funded through Measures M and R and is the seventh of Metro's 28 projects to be finished before the 2028 Olympic and Paralympic Games, serving the area around SoFi Stadium and Intuit Dome^[1]
It runs east from 67th Street and 11th Avenue to Slauson station, with 17 Metro bus lines, three DASH lines and five Metro Bike Share stations along the route^[1]
Streetsblog LA called it a dozen years in the making on a freight right of way abandoned since the 1970s; the western end is to be joined to the Crenshaw/K Line and the eastern end to Rail to River Segment B, which Metro says will eventually create a path to the LA River^[1][2]

Notable features

5.5 miles of separated bike and walking paths with rest areas, benches and new shade trees^[1]
Safety improvements for cyclists and pedestrians at crossings along the Slauson corridor^[1]
