The TBTA (Triboro Bridge and Tunnel Authority) pole was introduced in the 1950s for mid-twentieth-century bridge construction projects such as the Robert F. Kennedy Bridge (formerly the Triboro Bridge). The TBTA pole replaced wooden lampposts that lit parkways during the 1920s and ’30s. The Teardrop and Shielded Teardrop luminaires combine with the TBTA pole to produce a historic quality.
