This is a steel truss bridge, similar in structure to the current Schell. Itís arch is not nearly as high as the current Schell, however, and community input was that this design was highly favored if the arch could be made more like the current Schell. massDOT says that it will consider this.
This is a tunable steel tied arch bridge. The steel horizontal deck beams are fastened to the ends of the steel arches, tying them together so that they canít spread - therefore no horizontal forces on the piers. Tunable means the tensions in the vertical cables can be optimized for dead/live loads. Community input was for a cleaner, one-height railing. massDOT says it will consider this.
Similar to the tied arch design above, but having a cleaner railing system. The non-vertical cables are more reminiscent of the current Schell than the vertical cables; community input was mixed on vertical vs non-vertical cables. massDOT will consider a version with five pairs of vertical cables.
