The new 11-span bridge is comprised of three separate portions, two plate girder units, consisting of 10 spans totaling 1,908 ft, and the central 546-foot-long tied-arch span, perched 60 ft. above the main navigation channel. Overall, the new structure features two 12-foot driving lanes, each with 8-foot shoulders. |
