Preliminary research on different types of movable bridges and possible bridge locations was done throughout the summer. In September, it was chosen to redesign the Gray’s Ferry abandoned rail swing bridge over the Schuylkill River in Pennsylvania, Philadelphia. Research is being done on the types of mechanisms needed, the traffic across the bridge, and the environment and weather of the area. Research has also been done on how this bridge will be validated without a full moving prototype. ANSYS has been tested by the team members and optimal methods for creating a correct, verifiable geometry have been studied.  A trip to visit the site with the companies working on the new bridge is scheduled for next week. We have also obtained drawings and specifications for the current bridge to assist in beginning our design. We are currently studying the codes required for movable and pedestrian bridges and are deciding on an optimal design to fit the constraints due to the environment and the type of bridge.
