sentences:  A project to construct a stack interchange at I-410 (the "San Antonio Web") was completed June 9, 2008; formerly there was no direct access between the two freeways and surface streets were required to travel between the freeways.The reason for this initial lack of direct interchange was due to litigation filed in the late 1960s against the Texas Highway Department over the highway's original construction alignment through portions of Brackenridge Park and Olmos Park that were alleged to be in violation of several Federal laws, ultimately including NEPA.As a result of the Supreme Court decision in a more advanced and very similar case involving the proposed construction of I-40 through Overton Park in Memphis, Tennessee which upheld and affirmed the plaintiffs in that circumstance and precluded that highway's construction through the parkland with Federal funding, the Texas Highway Department chose instead to construct the McAlister Freeway entirely with State funding using a modified design that would increase curvature but limit encroachment into and noise impact on the Sunken Gardens area within Brackenridge Park.
