Ellipse bridge parabola

you have been asked to study the construction plans for a new bridge over the east river in new york city. the space between supports needs to be 1200 feet; the height at the center of the arch needs to be 400 feet. one company has suggested that the support in the shape of a parabola; another company suggested a semi-ellipse. the engineering team will determine the relative strengths of the two plans; your job is to find out if there are any differences in the channel widths for the two shape proposals. An empty tanker needs a 300-foot clearance to pass beneath the bridge. you need to find the width of the channel for each of the two different plans. how wide is the channel the tanker can pass through if the shape of the support is parabolic? I need the equation for the ellipse
