The correct answer is the #GlienickeBridge. (aka #Bridge of #Spies)
Whilst #GaryPowers and #RudolphAbel were probably better known to the public, #FredericPryor, who had been previously arrested in #EastBerlin, also formed part of the overall swap.
Pryor was released at #CheckpointCharlie in #Berlin, which, once confirmed, allowed the Powers/Abel swap to proceed.
The #BornholmerStraße #border crossing was one of the first points to be breached when the #BerlinWall fell in November, 1989.
