The first step for the team was to compare possible solutions for the unsustainable bridge. Some of the alternate solutions were repairing the old bridge, demolishing the old bridge and constructing a new one, relocating the bridge, or even redeveloping the zone into a recreational area and converting the old bridge into a pedestrian bridge. As ideas were brainstormed and examined, it became clear some of the alternatives would not be in the scope of possibilities due to given limitations. For example, repairing the bridge was no longer an option once the team discovered the levels of erosion the substructure had obtained. Once the team produced a series of effective alternate designs, they began looking into the different constraints that these designs bring. The constraints are the controlling factor of a design. A few of the constraints the team has come up with are local opinion, boat traffic, 100-year flood area, and impacts from high tides and storm surge flooding.

Bridge MA-14, was originally constructed in 1915 as a movable bridge and sometime in the late 70’s early 80’s, it was pinned together, which made it a fixed-span. To start off, The team decided on meet up times and set up weekly meetings with the advisors. From these meetings, the team has decided on the problem that we will be solving. This problem is that the bridge MA-14 is structurally deficient and functionally obsolete. The poor conditions of the superstructure, the substructure, and the low inventory rating make this bridge non repairable. Now that the team has decided on the problem that needs to be solved we started looking at different alternatives.
