Andrew Simko: We were driving over it in my friend’s old car when one of the boards came up through the rear floor. |

1966 Bridge
 |
| HistoricBridges "This bridge is unusual because most of the trusses are below deck except at the piers where they rise up forming a through truss design." This 2276' (394m) long bridge has a main span of 567' (173m). |
 |
| pghbridges "Its form is unusual hybrid: primarily a deck-type truss, but the panels are enlarged as they meet the piers. The top chord curves above the deck, but the side trusses are connected only at the vertical support above the piers. This upper cross-brace appears to be mostly cosmetic as the bracing below the deck is much more substantial." |
