Bicyclists and walkers today cover the ground that once hosted a vital Manteca economic link to United States markets. The 3.4-mile Tidewater Bikeway — named in honor of the former Tidewater Southern Railroad that operated trains into Manteca as late as 1983 — was dedicated in 2002. It slices through the middle of Manteca going from Lathrop Road in the north to Spreckels Avenue in the south.
