Pittsburgh is known for its steep hillsides covered with houses and streets which have steps for sidewalks. This mountainous topography and 3 vital rivers equal a city loaded with bridges. You'll find a total of 446 in the Steel City, 3 of which are known as the Sister Bridges and feature the identical golden supports seen here. Bridges Amplified was inspired by our Rocket League team and the need to amplify the importance of the Bridges in the Steel City.
