| Abstract: |
A mile-long signature replacement structure has been designed to replace the Woodrow Wilson Memorial Bridge on the I-95 Interstate System. With eight independent bascule leaves and a movable mass of 19000 metric tons, the bascule span is the largest movable bridge in the U.S. and possibly the world. To meet extraordinary public demands, the new bascule bridge has been constructed with many unique features including aesthetic V-shaped concrete piers, fully-composite concrete decks, moment-transferring span locking system, details to accommodate a future transit system, and a fully-redundant electrical control system. These components are amongst the innovative, interdisciplinary features described in this paper. |
